PHP: A tutorial.

Ordered Arrays

<?php
    $a[0] = 1;
    $a[1] = "foo";
    $a[]  = 1.57;
?>

Associative arrays

<?php
$catch_it['cat'] = "mouse";
$catch_it['dog'] = "cat";
?>

Manipulating

• Sorting: sort(), rsort(), ksort(), usort(), array_multisort()

• Traversal: reset(), end(), next(), each(), current(), key(), array_walk()

• Advanced: array_diff(), array_intersect(), array_merge(), array_merge_recursive(), array_slice(), array_splice() and lots more...
