#50042 [Bgs]: global variable not fully global when declared in a function within a function

ID: 50042 User updated by: adam dot jimenez at gmail dot com Reported By: adam dot jimenez at gmail dot com Status: Bogus Bug Type: Variables related Operating System: any PHP Version: 5.3.0 New Comment: //Global doesn't make a variable global but imports a variable fro mthe global scope (outside of all functions) into the current function/method. so how come it's added to the $GLOBALS array and can be accessed from outside the function?

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Global doesn't make a variable global but imports a variable fro mthe global scope (outside of all functions) into the current function/method. ------------------------------------------------------------------------ [2009-10-30 15:03:46] adam dot jimenez at gmail dot com Description: ------------ In the example function test2 is declared in function test. Function test2 declares the variable $test as global. $test is available inside test2 and outside the function but crucially not in function test. this may seem strange practice to declare a function within a function. but it can be useful in a function or class-based template system which is including other files and projects like wordpress. see: http://wordpress.org/support/topic/288455 Reproduce code: --------------- <?php function test() { function test2() { global $test; $test='nads'."\n"; } test2(); print $test; //doesn't work } test(); print $test; //works ?> Expected result: ---------------- nads nads Actual result: -------------- nads ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50042&edit=1
