error log handeling to custom file - php

Question

I want to log all error's that are generated whit error_reporting(E_ALL); in a logfile.
Thus the error's you normaly see when there is an error in the PHP script.
I tried many thing but the closest that i come was whit
asdasc(); // generate error
$i=error_get_last();
if($i['message']!==''){
error_log(date('Y-m-d-h:m:s') . " | type = " .$i ['type']." message = " .$i ['message']." file = " .$i ['file']." line = " .$i ['line'] , 3, "my-errors.log");}
This way i see that there was an error at a date,but what i want to see is what error i should see if it was on mine screen. something like :
SQLSTATE[HY000] [1045] Access denied for user 'root'#'localhost' (using password: NO) OR
Fatal error: Call to undefined function blabla() in C:\xampp\htdocs...\index.php on line 125
Is there a way to do this?
thnx in advanced.

Answer 1

Use error_get_last():
error_log(date('Y-m-d-h:m:s') . " | error = " . print_r(error_get_last(), true), 3, "my-errors.log");
You can as well set up your own error handling class in your application:
class MyErrorHandlerClass
{
public function MyErrorHandlerMethod($errno, $errmsg, $filename, $linenum, $vars)
{
// log you error
}
}
Then you can define your own error handler:
$ErrorHandler = new MyErrorHandlerClass();
set_error_handler(array($ErrorHandler, 'MyErrorHandlerMethod'));
error_reporting() btw. does not generate errors, it only controls the level of displaying errors. When an error occurs, its stack trace is always generated.
