Using strpos can be tricky sometimes. To reuse it for one search you can use this form:
<?php
$found = (strpos($haystack, $needle) !== false);
?>
For example:
<?php
$url = "http://www.binh.vn";
$found = (strpos($url, 'http') !== false);
if ($found) echo "Found http";
?>
Clearly we see that the position will be 0 but the $found will be true and so we can use more than
one time of if ($found) which is much easier.
To further reuse it we could make a very short function:
<?php
function found($haystack, $needle) {
return (strpos($haystack, $needle) !== false);
}
?>
Wonder why php didn't have such function for easier use?
