note 114687 added to function.strpos

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? ---- Server IP: 72.52.91.14 Probable Submitter: 42.113.166.72 ---- Manual Page -- http://php.net/manual/en/function.strpos.php Edit -- https://master.php.net/note/edit/114687 Del: integrated -- https://master.php.net/note/delete/114687/integrated Del: useless -- https://master.php.net/note/delete/114687/useless Del: bad code -- https://master.php.net/note/delete/114687/bad+code Del: spam -- https://master.php.net/note/delete/114687/spam Del: non-english -- https://master.php.net/note/delete/114687/non-english Del: in docs -- https://master.php.net/note/delete/114687/in+docs Del: other reasons-- https://master.php.net/note/delete/114687 Reject -- https://master.php.net/note/reject/114687 Search -- https://master.php.net/manage/user-notes.php
