Description: ------------ When function calls are handled by __call (PHP 5.x only), PHPShell will raise an Exception on line 346, because it uses method_exists() to check whether the function exists or not. Using is_callable() instead of method_exists() will handle __call()s correctly. A down side: is_callable() seems to always return TRUE if __call() exists. Test script: --------------- class Test { public function __call($methodName, $argList) { echo "$methodName called\n"; } } $t = new Test(); $t->doIt(); Expected result: ---------------- doIt called Actual result: -------------- Exception (code: 0) got thrown exception 'Exception' with message 'Variable $t (Class 'Test') doesn't have a method named 'doIt'' in /usr/local/lib/php/PHP/Shell.php:346 Stack trace: #0 /usr/local/lib/php/php-shell-cmd.php(116): PHP_Shell->parse() #1 {main}

Here is a patch to fix the bug. All it does is change all of the method_exists calls to is_callable. In reality, if __call() is defined, anything is callable. It is up to the developer to throw an exception if a method they don't want passed in is called. http://crisscott.com/tmp/PEAR/pear_bug_8554.patch
