How Can I Silently Suppress Warnings and Errors in My PHP Script?

Suppressing Warnings and Errors in PHP and MySQL

PHP and MySQL can generate notices and warnings that can be distracting or undesirable in certain situations. This article explores how to turn off these messages for a more streamlined experience.

Question:

I am encountering expected warnings and notices while working on a PHP script that I plan to use with a cron job. These messages are cluttering my logs and I would like to disable them. Is there a way to suppress these warnings and errors?

Answer:

Yes, it is possible to turn off warnings and errors in PHP. To do this, follow these steps:

1. Disable Warnings and Errors:

   To completely disable warnings and errors, add the following line to the beginning of your PHP script:

   error_reporting(E_ERROR);

   This line tells PHP to only report errors that are considered fatal and will suppress all other messages.

2. Log Errors (Optional):

   If you prefer to log errors instead of displaying them on the screen, you can set the error_log directive in your php.ini file or use a .htaccess file as follows:

   • php.ini:

     error_log = path/to/error.log

   • .htaccess:

     php_flag display_errors off
     php_flag log_errors on
     php_value error_log /home/path/public_html/domain/PHP_errors.log

   Additional Notes:

   It is recommended to turn on verbose error reporting during development to identify and fix any potential issues within your script. Use the following line for verbose reporting:

   error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

   Once your script is fully debugged and working correctly, you can then switch to the error_reporting(E_ERROR); line to suppress any unnecessary messages.
