PHP Error Types and Reporting

Understand notices, warnings, and fatal errors plus error_reporting levels.

PHP Error Types

PHP has several severity levels of errors:

  • Notice — minor issue, execution continues
  • Warning — non-fatal issue, execution continues
  • Fatal Error — execution stops immediately
  • Parse Error — syntax error, stops before execution
  • Deprecated — feature will be removed

error_reporting()

Control which errors PHP reports with error_reporting():

<?php
// Show all errors (development)
error_reporting(E_ALL);

// Hide notices and deprecated
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);

// Production: no display, log to file
error_reporting(E_ALL);
ini_set('display_errors', '0');
ini_set('log_errors', '1');
ini_set('error_log', '/var/log/php_errors.log');
