Detailed PHP error Log acquisition method, detailed PHP log acquisition

In PHP error log get a lot of ways, below I give you a brief introduction of how to solve this kind of problem, the following through the code to show you, hope to help everyone.

<?phperror_reporting (0); Register_shutdown_function ($err = ' My_error_handler ') OR Set_error_handler ($err, E_ALL); Register two functions at the same time.//function parameter Error $original = unserialize (Array (423142,2134234));//Not 0 except Echo 1/0;//does not exist array index echo $_get[' AA '];//does not exist The constant php_e;//does not exist for the variable echo $var;//function parameter error strlen (Array (2434));//function parameter error MD5 (Array (1));//user custom error Trigger_error (' Safdds ', e_ User_notice)///non-existent function PHP interrupt//TES ();//non-existent method php Interrupt $ts = new AFSD (); function My_error_handler ($errno =0, $errstr =0, $ERRF   Ile=0, $errline =0) {if ($errno && $errfile) {if (true) {$earr = array ();   $earr [' type '] = $errno;   $earr [' message '] = $ERRSTR;   $earr [' file '] = $errfile;  $earr [' line '] = $errline; }}else{$earr = Error_get_last ();} Echo '
'; Print_r ($earr); return array ();}
For PHP errors, we must understand clearly, types, when the trigger, the return value is what.
If you do not distinguish between the types of warnings, errors, suggestions, hints, etc., then we can understand that there are two types of PHP errors:
One is to force the interrupt program error. such as error, method does not exist, etc. Insufficient memory, timed out
A non-disruptive error. such as warnings, prompting these
Where getting an interrupt program error requires the use of the Register_shutdown_function function, registering a memory function, and then getting the error message inside, this method can only get to the first error line, such as multiple non-existent functions, it can only get to the first error. This is actually good, you fix one, it moves to the next.
Non-disruptive error, if used: register_shutdown_function, it will become extremely difficult to operate, only to get the first hint or warning, then we need to set_error_handler, every time the touch of error level  constants, the error function is called once, and you can get the error log inside. However, this function will take the Error_get_last function, so you will find that Error_get_last returns NULL, all passed by the parameter.
Two functions together, you can get to the program's 99% error, which for the PHP program, is the snow to send a lighter.
Try running the example above.
Through the combination of code and text to get the error log in PHP collation, I hope you will encounter such problems in the future work to help.
