Recently, I’ve started working on a few PHP projects on a local development machine and have been getting frustrating “500 internal server errors”. The machine is a a windows 7 PC running Apache server, PHP and MySQL.
Any coding bugs are much easier to locate and fix if a meaningful description of the error, along with a line number is displayed instead of the generic 500 page. If you have a similar issue, the solution probably lies within a quick update to the loaded php.ini configuration file. In Notepad, open the php file and locate the line (usually around 530) and change the line
display_errors = off to
display_errors = on
The php.ini file itself is usually in the php root folder from the install location but you can check the loaded php.ini file by navigating to a php page with the command
It is recommended however to only show friendly error messages during development or on a development machine for security reasons
Remember to restart the apache server for any changes to your php.ini file to take effect!
