'How do I enable error reporting in Laravel?

I'm using Laravel 5.2 and I'm trying to import an excel sheet which contains more than 18000 records. the error below appeared. The localhost page isn’t working

localhost is currently unable to handle this request.
HTTP ERROR 500

I tried to change php.ini max_execution_time from 30 seconds to 300 seconds but nothing has been changed

EDIT

the apache error log file says: [:error] [pid 3680:tid 1724] [client ::1:54491] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 24 bytes) in E:\..............



Solution 1:[1]

through your config/app.php set 'debug' => env('APP_DEBUG', false), to true

or in a better way , check out your .env file and make sure to set the debug element to true .

EDIT

according to the error in your apache2 log

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 24 bytes)

you need to increase your memory limit

ini_set('memory_limit', XXX);

Solution 2:[2]

ini_set('max_execution_time', 0);

set this at the start of your script, this will run your script forever and check your ipv4 address.

Solution 3:[3]

in .env file change APP_DEBUG to true

APP_DEBUG=true
