How can I make PHP display the error instead of giving me 500 Internal Server Error

Question

This has never happened before  Usually it displays the error  but now it just gives me a 500 internal server error  Of course before  when it displayed the error  it was different servers  Now I m on a new server  I have full root  so if I need to configure it somewhere in the php ini  I can   Or perhaps its something with Apache   I ve been putting up with it by just transferring the file to my other server and running it there to find the error  but that s become too tedious  Is there a way to fix this

Check the error reporting  display errors and display startup errors settings in your php ini file   They should be set to E ALL and  On  respectively  though you should not use display errors on a production server  so disable this and use log errors instead if when you deploy it   You can also change these settings  except display startup errors  at the very beginning of your script to set them at runtime  though you may not catch all errors this way    error reporting E ALL   ini set  display errors    On      After that  restart server

Use  php -l  lt filename gt    that s an  L   from the command line to output the syntax error that could be causing PHP to throw the status 500 error   It ll output something like   PHP Parse error   syntax error  unexpected     in  lt filename gt  on line 18

Enabling error displaying from PHP code doesn t work out for me  In my case  using NGINX and PHP-FMP  I track the log file using grep  For instance  I know the file name mycode php causes the error 500  but don t know which line  From the console  I use this    var log php-fpm  cat www-error log   grep mycode php   And I have the output    04-Apr-2016 06 58 27  PHP Parse error   syntax error  unexpected     in  var www html system mycode php on line 1458   This helps me find the line where I have the typo

Be careful to check if   display errors   or  error reporting   is active  not a comment  somewhere else in the ini file   My development server refused to display errors after upgrade to  Kubuntu 16 04 - I had checked php ini numerous times     turned out that there was a diplay errors   off  about 100 lines below my   display errors   on    So remember the last one counts

It s worth noting that if your error is due to  htaccess  for example a missing rewrite module  you ll still see the 500 internal server error
