i have to access an array within an array using php, and i have very little experience working with php.
can anyone point me towards a good tutorial or show me an example of how to go about it?
eg:
[0] contians [a],,[c]
many thanks

$somearray = array(
array('a' => 'Hello'),
array('b' => 'World')
);
echo $somearray[0]['a'] . ' ' . $somearray[1]['b'];
// Hello World
<?php
// Set array parts
$a = array("1" => "one", "2" => "two");
$b = array("a" => "aye", "b" => "bee");
$c = array("a scalar", $a, $b);
// Extract a sub-element from an array in the array
$d = $c[1][2];
// Extract a sub-array from the array
$e = $c[2];
// Display the various demonstration bits
print "<pre>\n\$c[2] = ";
print_r ($c[2]);
print "</pre>\n\n";
print "\$c[2]['b'] = {$c[2]['b']}<br>\n\n";
print "<pre>\n\$c[1] = ";
print_r ($c[1]);
print "</pre>\n\n";
print "\$d = $d<br>\n\n";
print "<pre>\n\$e = ";
print_r ($e);
print "</pre>\n\n";
print "\$c[0] = $c[0]<br>\n";
?>
Watch the syntax when printing. PHP's parser is a little dicey in that situation; arrays often need to be braced when printing directly.
thanks for the advice
so using the first example:
if [0] had [a][c]
all i'd need to do to access an array and assign the contents to vars would be (using first example):
$avar = $somearray[0]['a'];
$bvar = $somearray[1]['b'];
echo $avar;
echo $bvar;
// Hello
// World

Precisely. If you want to get really deep into how arrays work take a look at the language documentation. http://php.net/arrays
