Bug #68075 [NEW]: Functions defined in closures may not be called before definition

From: fieryprophet at yahoo dot com Operating system: All PHP version: Irrelevant Package: Scripting Engine problem Bug Type: Bug Bug description:Functions defined in closures may not be called before definition Description: ------------ PHP allows calls to functions that have not yet been defined as long as they are defined at some point in the script. However, this behavior is not consistent when applied to Closures, as function calls within a closure will fail if they are not defined before they are made even if the function definition is contained within the same closure. If the function in question is defined outside of a closure but after the closure is created, the script will also proceed as expected. Test script: --------------- test(); function test(){ echo "Test works\r\n"; } //output: Test works $closure = function(){ closure_test(); function closure_test(){ echo "Closure test works\r\n"; } }; $closure(); //expected output: Closure test works //actual output: Fatal error: Call to undefined function closure_test() Expected result: ---------------- Test works Closure test works Actual result: -------------- Test works Fatal error: Call to undefined function closure_test() -- Edit bug report at https://bugs.php.net/bug.php?id=68075&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68075&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68075&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68075&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68075&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68075&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68075&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68075&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68075&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68075&r=support Expected behavior: https://bugs.php.net/fix.php?id=68075&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68075&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68075&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68075&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68075&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68075&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68075&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68075&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68075&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68075&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68075&r=mysqlcfg
