note 104127 added to function.preg-match

Testing the speed of preg_match against stripos doing insensitive case search in strings: <?php $string = "Hey, how are you? I'm a string."; // PCRE $start = microtime(true); for ($i = 1; $i < 10000000; $i++) { $bool = preg_match('/you/i', $string); } $end = microtime(true); $pcre_lasted = $end - $start; // 8.3078360557556 // Stripos, we believe in you $start = microtime(true); for ($i = 1; $i < 10000000; $i++) { $bool = stripos($string, 'you') !== false; } $end = microtime(true); $stripos_lasted = $end - $start; // 6.0306038856506 echo "Preg_match lasted: {$pcre_lasted}<br />Stripos lasted: {$stripos_lasted}"; ?> So unless you really need to test a string against a regular expression, always use strpos / stripos and other string functions to find characters and strings within other strings. ---- Server IP: 80.64.47.13 Probable Submitter: 87.216.160.9 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/104127 Del: integrated -- https://master.php.net/note/delete/104127/integrated Del: useless -- https://master.php.net/note/delete/104127/useless Del: bad code -- https://master.php.net/note/delete/104127/bad+code Del: spam -- https://master.php.net/note/delete/104127/spam Del: non-english -- https://master.php.net/note/delete/104127/non-english Del: in docs -- https://master.php.net/note/delete/104127/in+docs Del: other reasons-- https://master.php.net/note/delete/104127 Reject -- https://master.php.net/note/reject/104127 Search -- https://master.php.net/manage/user-notes.php
