php Array question

[marrithl2]

I am trying to print the results of this code:

$cmpResult = array_intersect($productList2, $totalProductList);
print_r("cmpResult:"); ?><br /><?php
print_r($cmpResult); ?><br /><?php

but the output is "Array ( )". How do I get it to output the values of the intersect?

[theighost]

foreach($cmpResult as $cmpResult)
print_r($cmpResult);

The above code should work

[vibhaJ]

also post what you are getting as a result in
print_r($productList2) and print_r($totalProductList)

Return result as we need:

<?php
$artists = array('Metallica', 'Evanescence', 'Linkin Park', 'Guns n Roses');
$pasta = array('spaghetti', 'penne', 'Evanescence');
$cmpResult = array_intersect($artists, $pasta);
echo "<br/><br/>";
print_r("cmpResult:");
echo "<br/>";
print_r($cmpResult);
?>
