PHP: stripos doesn't find a value

Question

I need to find one of the three words even if written at the beginning of the string and not just in the middle or at the end. This is my code:

<?php
$string = "one test";
$words = array( 'one', 'two', 'three' );
foreach ( $words as $word ) {
    if ( stripos ( $string, $word) ) {
        echo 'found<br>';
    } else {
        echo 'not found<br>';
    }
}
?>

If $string is "one test" the search fails; if $string is "test one" the search is good.

Thank you!

Answer 1

stripos can return a value which looks like false, but is not, i.e. 0. In your second case, the word "one" matches "one test" at position 0 so stripos returns 0, but in your if test that is treated as false. Change your if test to

if ( stripos ( $string, $word) !== false ) {

and your code should work fine.
