note 81389 added to language.functions

Note that if you have the name of function in a variable, then you can call it, if that function is globally available. It cannot be the name of a function in a class. An example: class foo { public static function bar(){ return "bar in a class called"; } } function bar() { return "normal bar called"; } $strFN = "bar"; echo $strFN(); $strFN2 = "foo::bar"; echo $strFN2(); This will result in normal bar called Fatal error: Call to undefined function foo::bar() in /path/to/test.php on line 16 ---- Server IP: 64.71.164.2 Probable Submitter: 128.208.3.29 ---- Manual Page -- http://www.php.net/manual/en/language.functions.php Edit -- https://master.php.net/note/edit/81389 Del: integrated -- https://master.php.net/note/delete/81389/integrated Del: useless -- https://master.php.net/note/delete/81389/useless Del: bad code -- https://master.php.net/note/delete/81389/bad+code Del: spam -- https://master.php.net/note/delete/81389/spam Del: non-english -- https://master.php.net/note/delete/81389/non-english Del: in docs -- https://master.php.net/note/delete/81389/in+docs Del: other reasons-- https://master.php.net/note/delete/81389 Reject -- https://master.php.net/note/reject/81389 Search -- https://master.php.net/manage/user-notes.php
