How to get all the strings after = sign in php

[Clanstrom]

Hi,

I have a lot URLs in my site that look like: http://localhost/DIRECTORY/FINAL/ref.php?id=category

Now, I need a PHP function to search for = Sign and return all the text after that i.e. 'category'

Is this possible, if so can anyone help

[Zagga]

$id = $_GET['id'];

?

No with out that one! Because, I have Id,Ref,Profile,Article,Event ... I can not make the get function for all. I was thinking, something handy with the regex function

$_GET is an array, not a functon.

If your URL was http://localhost/DIRECTORY/FINAL/ref.php?id=category&another=test&another2=test2 for example, you could use

$_GET['id']
$_GET['another']
$_GET['another2']

Thank you for trying to help me guys, but I have this problem wich wasted four hours of my time now, and I can't get it fixed.

    function seo($seo_type){
    if(isset($_GET['a_id']) && !empty($_GET['a_id'])) {

    $number = $_GET['a_id'];
    $query = "SELECT $seo_type FROM d_articles WHERE a_id = '$number'";
    $result = mysql_query($query);

    while($row=mysql_fetch_array($result))
    { echo "$row[$seo_type] - ";    }

    } 
    }

What the above function does is, get id of url ex. site.com/article.php?a_id=77
Now, the function calling is like this, <?php echo seo('page_title'); ?>

Now, when you call the function, it searches page_title FROM d_articles wheere
a_id = 77

Now, it does query and gets results from sql and echos it. Which is good.
But, what if the url does not end with articles.php?a_id=77
What if I have another url that is referece.php?id=22 or user.php?id=44

So, the question boils down to

how can you check what kind of id exists and perform seperte functions as per the function that exits

[Zagga]

Hi,

So you are trying to get either a_id or id from the URL, depending on which one exists?

if(isset($_GET['a_id']) && !empty($_GET['a_id'])){
    $number = $_GET['a_id'];
} elseif (isset($_GET['id']) && !empty($_GET['id'])){
    $number = $_GET['id'];
}

You can add as many variations as you need.

If you really want to get the whole string after the ? you can use something like:

$id = strstr($_SERVER['PATH_INFO'], '?');
$id = str_replace('?','',$id);
