Search string in array

[Panjabel]

<?php 
$list1 = array("cv1","cv2","cv3"); 
$list2 = array("cv1s","cv2","cv3d"); 
foreach($list1 as $list) 
{ 
//if $list exists in array $list2 i want to print it, else not to print it 
} 
?> 

I've searched for this but i found, if i'm searching for "cv1" in "cv1" it finds it but if i'm searching for "cv1" in "cv1s" it doesn't

Thanks in advance

Like this?

 

$list1 = array("cv1","cv2","cv3"); 
$list2 = array("cv1s","cv2","cv3d"); 
foreach($list1 as $v1){ 
foreach($list2 as $v2){
	if(strpos($v2,$v1) !== FALSE){
		echo $v1.'<br />';
	}
}
}
