Previous Comments: ------------------------------------------------------------------------ [2012-11-23 19:37:12] lubosdz at hotmail dot com What about function_exists() ? set_error_handler(function($errno , $errstr){ if (!function_exists('there_is_no_me')) { function there_is_no_me(){ echo "Here am I!\n"; } } }); lubosdz ------------------------------------------------------------------------ [2012-11-16 10:13:02] indeyets@php.net Description: ------------ At the moment, call to undefined function results as "Fatal error". On the other hand, it can be easily handled programmatically either by including required file or just defining function dynamically. Test script: --------------- <?php set_error_handler(function($errno , $errstr){ if (strpos($errstr, 'Call to undefined function there_is_no_me()') === 0) { function there_is_no_me() { echo "Here am I!\n"; } } }); there_is_no_me(); Expected result: ---------------- Here am I! Actual result: -------------- Fatal error: Call to undefined function there_is_no_me() ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63538&edit=1
