Req #63655 [Com]: check type functions -> check type operators

Edit report at https://bugs.php.net/bug.php?id=63655&edit=1 ID: 63655 Comment by: jtrumbull at gmail dot com Reported by: sailormax at inbox dot lv Summary: check type functions -> check type operators Status: Open Type: Feature/Change Request Package: Performance problem PHP Version: 5.3.19 Block user comment: N Private report: N New Comment: it would appear cast conversion and comparison is only 2x faster when the result is TRUE, it is 3x slower when the answer is FALSE Previous Comments: ------------------------------------------------------------------------ [2013-01-02 13:01:59] vincent at lycoops dot be This is true for simple scalars, yes. But for large strings, array and objects, it is wrong. But I agree that this should really be added. ------------------------------------------------------------------------ [2012-11-30 11:11:17] sailormax at inbox dot lv Description: ------------ Currently check type functions (is_string, is_int, is_float, is_bool, is_object, is_array) are functions. They are very often use in many engines. But because they are functions - they are very slow for engines. In result engine authors have to use faster alternatives (~2x faster) like: is_string => ((string)$var === $var) is_int => ((int)$var === $var) is_float => ((float)$var === $var) is_bool => ((bool)$var === $var) is_object => ((object)$var === $var) is_array => ((array)$var === $var) Can you compile this type of functions as operators? thank you. Test script: --------------- $ts = microtime(true); for ($i=0; $i<50000; $i++) $res = is_string($_GET); var_dump(microtime(true) - $ts); print "<br /><br />"; $ts = microtime(true); for ($i=0; $i<50000; $i++) $res = ((string)$_GET === $_GET); var_dump(microtime(true) - $ts); print "<br /><br />"; Expected result: ---------------- equal time Actual result: -------------- is_string ~ 2x slower than ((string)$_GET === $_GET) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63655&edit=1
