Hey guys/gals,

I am trying to output only the items in the array that have ISBN in it. I tried both array_search() and in_array() functions and each time I got errors for using invalid data types in the second field.

Code:

<?php

$test = array('Wfjheighe','ISBN:454656','ISBN:9090943');


    foreach ($test as $id) {
    
    	
      if(array_search('ISBN',$id)) echo $id . "<BR />";
    
    }


?>

AND


<?php

$test = array('Wfjheighe','ISBN:454656','ISBN:9090943');


    foreach ($test as $id) {
    
    	
      if(in_array('ISBN',$id)) echo $id . "<BR />";
    
    }


?>

I basically just want ISBN:454656 and ISBN:9090943 to be outputted...

What am I doing wrong?
