PHP errors are not displayed by default. If an error occurs, you will simply get a blank page. This is for security reasons: this way, an attacker doesn't know about possible vulnerabilities of your website. If you want to see PHP errors, you can log them to a file, or enable the display of errors. Note that it can take up to 5 minutes for any of the options mentioned below to be detected.
Logging errors to a file
If your username is foobar, create a .user.ini file (for example: ~/www/.user.ini) with this content, if you are a regular user:
log_errors = on error_log = "/home/user/foobar/php_error.log"
Or if you are an organization:
log_errors = on error_log = "/home/org/foobar/php_error.log"
Displaying errors
Create a .user.ini file (for example: ~/www/.user.ini) with this content:
display_errors = on
Note that PHP errors may include sensitive information, and enabling display_errors will cause that to be visible to the entire internet. It is therefore advised to only enable display_errors when actively troubleshooting a problem. Instead use an error log as specified above.
