Works for me in PHP 5:
----
>cat a.php
<?php
echo phpversion(), "\n";
$a1 = array (array (1,2,3,4), array ('a','b','c'), array (true, false));
$a2 = array_slice ($a1, 1, 2);
var_dump ($a2);
>php5 a.php
5.2.5
array(2) {
[0]=>
array(3) {
[0]=>
string(1) "a"
[1]=>
string(1) "b"
[2]=>
string(1) "c"
}
[1]=>
array(2) {
[0]=>
bool(true)
[1]=>
bool(false)
}
}
----
When I first looked into array_slice, I was hoping that it
could be used to extract a "column" from a multi-dimensional
array, e.g.:
array_slice ($a1, 1)
would result in:
array (2, 'b', false)
This would be very useful at times, but doesn't seem
to be possible.
