php problem: strpos function not working

Question

why is the following php code not working:

$string = \"123\";
$search = \"123\";

if(strpos($string,$search))
{
    echo \"found\";
}else{
    echo \"not fou         


        

Answer 1

strpos returns the first offset where $search was found - 0. 0 in turn evaluates to false. Therefore the if fails.

If $search was not found, strpos returns FALSE. First check the return value for !== FALSE, and then check the offset.

Thanks to everyone who pointed this out in the comments.
