Matching Letters In An Array

Question

Joe34 0 Junior Poster in Training

12 Years Ago

I'm trying to simply match these letters using php, but it's kind-of a complex matching formula...

First, I have two arrays and one string. The arrays contain letters and the string is a near match of those letters.

$a - [Array] Must be <= 7
$b - [Array] Must be >= 0
$word - [String] Must contain letters from $a & $b. Letters can't be used twice.

The Goal: Create a word from those letters with complex matching. To start each word must contain one and only one $b letter, unless no $b letters are given. Next it must make sure that $word only contains letters from $a (it can't use letters twice but $a can contain the same letter) (and of course one or zero $b letters).

Example #1:
$a = R-E-O-E
$b = E-P
$word = Red
(The code should look at this an not accept it because $a nor $b doesn't contain a D)

Example #2:
$a = R-E-O-E
$b = E-P
$word = Peer
(The code should accept this because $b contains P and $a contains two E's and an R)

Note: This will be in a long loop with many different words.

Any help will be greatly appreciated!

Try this:

<?php

$a = array('test','text','ext','tex','deer'); # words to filter
$b = array('e','s','t','d','r'); # letters to check

function c($letter,$array)
{
        $n = strlen($letter);
        $r = array();
        for($i = 0; $i < $n; $i++)
        {
                if(in_array($letter[$i],$array))
                {
                        $r[] = true;
                }
                else
                {
                        $r[] = false;
                }
        }
        return (in_array(null,$r)) ? false:true;
}

foreach($a as $word)
{
        echo $word .': '. c($word,$b) . "\n";
}
?>

bye.

I'm sorry, now it should work like you want:

<?php
$a = array('e','x','t','d','a');
$b = array('r','g','n');
$word = 'extra'; # try "gextra" for example, because of g and r it will give false

function c($word,$array,$barray)
{
	$n = strlen($word);
	$r = array();
	$bn = 0;
	for($i = 0; $i < $n; $i++)
	{
		if(in_array($word[$i],$array))
		{
			$r[$i] = true;
		}
		else
		{
			$r[$i] = false;
		}

		if(in_array($word[$i],$barray))
		{
			if($bn == 0)
			{
				$bn = 1;
				$r[$i] = true;
			}
			else
			{
				$r[$i] = false;
			}
		}
	}

	return (in_array(null,$r)) ? false:true;
}

echo $word .': '. c($word,$a,$b) . "\n";
echo "\n";
?>

Try it and let me know, I've tried to match your examples..

	$a = array();
	foreach($u2 as $k => $v)
	{
    	$a[] = ($a1[$v] >= $w1[$v]) ? true:false;
	}

	$d = in_array(false,$a) ? false:true;
	return $d;
}

Looks like an infinite loop.

for ($i = count($items) - 1; $i >= 0; --$i) {

It's not reaching -1.

Perhaps echoing $i in the loop will show you what's going on. Maybe:

for ($i = count($items) - 1; $i >= 0; $i--) {

This works without errors, unless input is too long and the execution time goes over 30 seconds, at that point PHP will stop the script and return part of the output and an error. For this reason I added a length check at the end of the script, otherwise you have to increase max_execution_time.

<?php

if(empty($_POST['yl']))
{
    echo "<form action='index.php' method='POST'>
    Your Letters: <input type='text' name='yl' value='oor'>
    Board Letters: <input type='text' name='bl' value='dt'>
    <input type='submit'></form>";
}
else
{
    $replace = array(',',' ','','-');
    $a = str_split(str_replace($replace,'',$_POST['yl']));
    $b = str_split(str_replace($replace,'',$_POST['bl']));

    # removable
    echo '<h5>input</h5><pre>';
    print_r($a);
    print_r($b);
    echo '</pre>';

    function pc_permute($items, $perms = array( )) {

        global $a;
        global $b;
        global $d;
        global $e;
        
        if (empty($items)) {
            $w = join('', $perms);
	        $pspell_link = pspell_new("en"); # set language

	        $suggestions = pspell_suggest($pspell_link, $w);

Is this the output you are searching for? I'm still in doubt.. hehe :D

P.S. also consider for Pritaeas suggestion, something in C# or C++ may be hugely faster than PHP: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/408526/1748151#post1748151

Try this:

<?php

$a = array('test','text','ext','tex','deer'); # words to filter
$b = array('e','s','t','d','r'); # letters to check

function c($letter,$array)
{
        $n = strlen($letter);
        $r = array();
        for($i = 0; $i < $n; $i++)
        {
                if(in_array($letter[$i],$array))
                {
                        $r[] = true;
                }
                else
                {
                        $r[] = false;
                }
        }
        return (in_array(null,$r)) ? false:true;
}

foreach($a as $word)
{
        echo $word .': '. c($word,$b) . "\n";
}
?>

bye.

Great suggestion, but that isn't really what I'm looking for. If you look back at my example I explain two different arrays and one word.

Thanks for trying!

You're smart, but not quite there yet! For example, I tried the word "exta" which contains no letters from the $b array. Each word must contain letters from the $b array unless no letters are in the $b array.

Another problem is if I do the word "exxtra" it contains two x's, but the $a array only contains one x.

Thanks!

Looks like an infinite loop.
for ($i = count($items) - 1; $i >= 0; --$i) {
It's not reaching -1.
Perhaps echoing $i in the loop will show you what's going on. Maybe:
for ($i = count($items) - 1; $i >= 0; $i--) {

Okay I added the echo $i, but it still never seems to end and it looks like this...

This works without errors, unless input is too long and the execution time goes over 30 seconds, at that point PHP will stop the script and return part of the output and an error. For this reason I added a length check at the end of the script, otherwise you have to increase max_execution_time.

<?php

if(empty($_POST['yl']))
{
    echo "<form action='index.php' method='POST'>
    Your Letters: <input type='text' name='yl' value='oor'>
    Board Letters: <input type='text' name='bl' value='dt'>
    <input type='submit'></form>";
}
else
{
    $replace = array(',',' ','','-');
    $a = str_split(str_replace($replace,'',$_POST['yl']));
    $b = str_split(str_replace($replace,'',$_POST['bl']));

    # removable
    echo '<h5>input</h5><pre>';
    print_r($a);
    print_r($b);
    echo '</pre>';

    function pc_permute($items, $perms = array( )) {

Is this the output you are searching for? I'm still in doubt.. hehe :D

P.S. also consider for Pritaeas suggestion, something in C# or C++ may be hugely faster than PHP: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/408526/1748151#post1748151

Thanks for the reply. That still isn't what I'm looking for. You see, I don't really want the words to repeat. With your code here is the beginning of my output...

Notice that Bord and Bord repeats. I want no repeats...

Ok, I changed permutation function, it's taken always from that article: http://docstore.mik.ua/orelly/webprog/pcook/ch04_26.htm
Previously it was hard to return the output from the function, now I created a class:

<?php
# filename perm.class.php
Class Perm
{

    public function start($arrayA,$arrayB)
    {
        $c = array_merge($arrayA,$arrayB);
    
        if(count($c) > 5)
        {
            return 'too long';
        }
        else
        {
            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do {
                 foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            } while ($perm = $this->p($perm, $size) and ++$j);

            $list = array();
            foreach ($perms as $p) {
                $list[] = join('', $p);
            }
            
            return array_unique($this->ps($list));
        }
    }
    
    # generate permutations
    private function p($p, $size) {
        for ($i = $size-1; @$p[$i] >= $p[$i+1]; --$i) { }
        if ($i == -1) { return false; }
        for ($j = $size; $p[$j] <= $p[$i]; --$j) { }

        $tmp = $p[$i];
        $p[$i] = $p[$j];
        $p[$j] = $tmp;

        for (++$i, $j = $size; $i < $j; ++$i, --$j) {
             $tmp = $p[$i];
             $p[$i] = $p[$j];
             $p[$j] = $tmp;
        }

        return $p;
    }

    # count and compare values between array a and word 
    private function d($word, $array)
    {
	    global $d;
	    $u = array_unique($array);
	    $w = str_split($word);
     
	    $u2 = array_intersect($u,$w);
	    $a1 = array_count_values($array);
	    $w1 = array_count_values($w);
	    $a = array();
	    foreach($u2 as $k => $v)
	    {
        	$a[] = ($a1[$v] >= $w1[$v]) ? true:false;
	    }
     
	    $d = in_array(false,$a) ? false:true;
	    return $d;

					    $r[] = 2;
				    }
			    }
			    else
			    {
				    $r[] = 3;

		    }
	    }
	    elseif(count($barray) == 0 && is_array($barray))
	    {
	        $r[] = 1;
	    }
	    else

    {
        global $a;
        global $b;
        $n = count($list);
        $pspell_link = pspell_new("en"); # set language
        $z = array();
        for($i = 0; $i < $n; $i++)
        {
            $suggestions = pspell_suggest($pspell_link, $list[$i]);
            foreach ($suggestions as $suggestion)
            {
                if(strlen($suggestion) > 1)
                {
                    $s = strtolower($suggestion);
                    $this->d($s,$a);
                    $this->e($s,$b);
                      
                    if($this->c($s,$a) == true)
                    {
                        $z[] = $s;
                    }
                }
                    
            }        
        }
        return $z;
    }
}
?>

And this is the page where you have to include the class:

<?php
include 'perm.class.php'; # include class

# page outputs

if(empty($_POST['yl']))
{
    echo "<form action='n.php' method='POST'>
    Your Letters: <input type='text' name='yl' value='oor'>
    Board Letters: <input type='text' name='bl' value='dt'>
    <input type='submit'></form>";
}
else
{
    $replace = array(',',' ','','-');
    $a = str_split(str_replace($replace,'',$_POST['yl']));
    $b = str_split(str_replace($replace,'',$_POST['bl']));
    echo '<h5>input</h5><pre>';
    print_r($a);
    print_r($b);
    echo '</pre>';

    # start
    $play = new Perm();
    echo '<pre>';
    print_r($play->start($a,$b)); # you only need this to get results
    echo '</pre>';
}
?>

Files are attached, the only problem is:

Notice: Undefined offset: -1 in /var/www/test/m/perm.class.php on line 35

which is not shown because I placed a @ (booo on me), but right now I just can't get that straight.. too tired ^_^

Just an add, on line 178 of the class you can change the conditional statement to:

if($this->c($s,$a) == true && ctype_alpha($s))

this will remove results like root's, odor's and the others.

One last problem. If I don't put in a character in the board letters text box nothing comes back.

I would like (if there are no letters in the $b array) for it to find as many words as possible using just the $a array.

Great job!

You can increase results by setting flags in pspell config as explained here: http://www.php.net/manual/en/function.pspell-config-mode.php
If it still doesn't match, please provide an example. Bye :)

You can increase results by setting flags in pspell config as explained here: http://www.php.net/manual/en/function.pspell-config-mode.php
If it still doesn't match, please provide an example. Bye :)

It still didn't work...

I entered in "rd" and "e" and got these results...

It shouldn't contain letters that weren't entered.

[0] => red
[1] => ride
[3] => rode
[4] => rude
[5] => rte
[7] => redo
[8] => rued
[9] => rodie
[10] => rudie
[11] => rodeo
[12] => rate
[13] => rite

So if you set rde you want to get only:

Array
(
    [0] => red
    [1] => dre
    [2] => de
    [4] => re
    [9] => ed
    [12] => der
    [21] => er
)

Am I right? If yes maybe we got it, now there is a function at the end, that will check only for words containing set letters:

Just an update on function start() this will speed up the execution and use less memory:

public function start($arrayA,$arrayB)
    {
        global $a;
        global $b;
        global $c;
        
        $replace = array(',',' ','','-');
        $a = str_split(str_replace($replace,'',$arrayA));
        
        if(empty($arrayB))
        {
            $bArr = false;
            $b = array();
        } else {
            $bArr = true;
            $b = str_split(str_replace($replace,'',$arrayB));
        }
        
        $c = ($bArr == false) ? $a : array_merge($a,$b);
        
        if(count($c) > 5)
        {
            return 'too long';
        }
        elseif(count($c) <= 1)
        {
            return 'too short';
        }
        else
        {
            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do
            {
                foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            }
            while($perm = $this->p($perm, $size) and ++$j);
            
            $list = array_map('join',$perms);
            $list = array_unique($list);
            $list = array_merge(array(),$list);
            $list = array_unique($this->ps($list));
            $result = array_merge(array(),$list);
            
            return $result;
        }
    }

The permutation function p() creates a lot of duplicates, so using $list = array_unique($list); helps to reduce data sent to function ps(). Bye.
