arrays - PHP array_intersect() - how does it handle different types? -

if i've got array of values zerofilled string representations of various numbers , array of integers, array_intersect() still match elements of different types?

for example, work:

$arrayone = array('0003', '0004', '0005'); $arraytwo = array(4, 5, 6);  $intersect = array_intersect($arrayone, $arraytwo);  // $intersect = "array(4, 5)" 

... , if not, efficient way accomplish this? loop through , compare, or loop through , convert integers , run array_intersect() after, or ...

$ cat > test.php

<?php $arrayone = array('0003', '0004', '0005'); $arraytwo = array(4, 5, 6);  $intersect = array_intersect($arrayone, $arraytwo);  print_r($intersect );  ?> 

$ php test.php

array ( )

$

so no, not. if add

foreach($arrayone $key => $value) {    $arrayone[$key] = intval($value); } 

you

$ php test.php

array ( [1] => 4 [2] => 5 )
