Bug description:Implement ability to recover from fatal errors in eval()'d code
Description:
------------
Sometimes eval() is used as a way to execute PHP code within a shell (legal
remote access for debugging purposes) or to execute code compiled to PHP
from higher-level scripting language or the code stored in the database
etc.
The common problem is that a call of non-existing function (or object
instantiation) results in termination of the whole script, not just eval'd
code.
I think that it's not correct in such cases.
The obvious way to implement it would be adding flags to eval() function
(as a second argument) one of which could indicate that eval() should not
terminate the script but just return an error or raise an exception.
Such flags could be:
EVAL_FATAL_DIE // current behavior
EVAL_FATAL_ERROR // return FALSE
EVAL_FATAL_EXCEPTION // raise an exception of a predefined class (e.g.
EvalException)
Test script:
---------------
try {
eval('non_existing_function()', EVAL_FATAL_EXCEPTION);
}
catch (EvalException $e) {
Logger::log('Error in eval\'d code', $e);
}
Expected result:
----------------
Exception being logged and script continued its execution.
Actual result:
--------------
Fatal error: Call to undefined function non_existing_function() in ... :
eval()'d code(1) on line 1
