Req #64185 [Com]: is_callable does not check syntax

Edit report at https://bugs.php.net/bug.php?id=64185&edit=1 ID: 64185 Comment by: hanskrentel at yahoo dot de Reported by: hanskrentel at yahoo dot de Summary: is_callable does not check syntax Status: Open Type: Feature/Change Request Package: Scripting Engine problem PHP Version: 5.4.11 Block user comment: N Private report: N New Comment: NikiC was so friendly to just remind me that checking for the method name *is* limited because of __call and __callStatic (basically everything for a method name works, including a zero-length string). So this feature request is actually more about the classname validation then the method name validation. Previous Comments: ------------------------------------------------------------------------ [2013-02-10 16:04:21] hanskrentel at yahoo dot de Description: ------------ Using is_callable with the syntax_only parameter set to true does actually *not* check the syntax, for example of a valid classname or FQCN. Also not for the method name. My feature request is, that it will always check those strings according to the rules set in the PHP parser of the same PHP version the function ships with so that it can be used to validate PHP syntax as well. Same for calls with :: for static class name method calls. Test script: --------------- var_dump(is_callable(['', ''], true)); var_dump(is_callable(['', 'method'], true)); var_dump(is_callable(['0', 'method'], true)); var_dump(is_callable(['0\\foo', 'method'], true)); var_dump(is_callable(['\\0\\foo', 'method'], true)); Expected result: ---------------- bool(false) bool(false) bool(false) bool(false) bool(false) Actual result: -------------- bool(true) bool(true) bool(true) bool(true) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64185&edit=1
