Question

I have an application based on Zend Framwork. In one Model I am calling a method from another Model. When I call this method I use try-cath block for handling of strange situations.
Model1.

try {
   $result  =  Module_Model2_Name->method();
} catch (Exception $e) {
   // Do Something
}

Catch should be work if we find a throw in try block. But I don’t know about behaviour of my application. If it is a some application error in Model2 method it should be throw an Exception.
In method of Model2 I do the next thing, but it doesn’t work:

set_error_handler(create_function('$m = "Error"','throw new Exception($m);'), E_ALL);

How can I throw an Exception on every PHP application error?
Thank you very much. Sorry for my English.

Answer 1

It looks good to me (tested it).

<?php
set_error_handler(create_function('$nr, $msg = "Error"','throw new Exception($m);'), E_ALL);
try{
    foreach($notHere as $var){}
}
catch(Exception $e){
    var_dump($e);
}
?>

Please note that:

The following error types cannot be
handled with a user defined function:
E_ERROR, E_PARSE, E_CORE_ERROR,
E_CORE_WARNING, E_COMPILE_ERROR,
E_COMPILE_WARNING, and most of
E_STRICT raised in the file where
set_error_handler() is called.

Taken from the PHP manual.
