Req #63655 [NEW]: check type functions -> check type operators
From: sailormax at inbox dot lv
Operating system:
PHP version: 5.3.19
Package: Performance problem
Bug Type: Feature/Change Request
Bug description:check type functions -> check type operators
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)
