PHP arrays are always associative:
> cat array.php
#!/usr/bin/env php
<?php
error_reporting( E_ALL );
$a = array( 1, 2, 3 );
$b = array( 'a', 'b', 'c' );
$c = array( 1, '2', 'x' );
print_r( $a );
print_r( $b );
print_r( $c );
> ./array.php
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Array
(
[0] => a
[1] => b
[2] => c
)
Array
(
[0] => 1
[1] => 2
[2] => x
)

Errors should be handled not suppressed.
