Are your PHP scripts not working, but you’re seeing a blank page? Don\u2019t worry \u2014 this is common when PHP errors and warnings<\/strong> are turned off.<\/p>\n\n\n\n

Learning how to display PHP errors<\/strong> is essential for debugging and fixing problems quickly. In this beginner-friendly tutorial, you\u2019ll learn how to enable PHP error reporting<\/strong>, show PHP warnings<\/strong>, and set up your server to make debugging easier.<\/p>\n\n\n\n

Whether you’re using XAMPP, MAMP, or a live server, this guide will help you turn on full PHP error visibility step by step.<\/p>\n\n\n\n

Why Display PHP Errors?<\/h2>\n\n\n\n

Showing errors helps you:<\/p>\n\n\n\n

    \n
  • Spot bugs and fix them fast<\/li>\n\n\n\n
  • Understand what\u2019s going wrong<\/li>\n\n\n\n
  • Improve code quality<\/li>\n\n\n\n
  • Save time during development<\/li>\n<\/ul>\n\n\n\n

    1. Show Errors with PHP Code<\/h2>\n\n\n\n

    Add these lines at the top of your PHP file:<\/p>\n\n\n\n

    ini_set('display_errors', 1);
    ini_set('display_startup_errors', 1);
    error_reporting(E_ALL);<\/code><\/pre>\n\n\n\n
    This will make PHP show all errors and warnings on the screen.<\/p>\n\n\n\n
    2. Show Errors Using php.ini<\/code> (Server Settings)<\/h2>\n\n\n\n
    If you want errors to show on all files:<\/p>\n\n\n\n
      \n
    1. Open your php.ini<\/code> file<\/li>\n\n\n\n
    2. Find and change:<\/li>\n<\/ol>\n\n\n\n
      display_errors = On
      display_startup_errors = On
      error_reporting = E_ALL<\/code><\/pre>\n\n\n\n
        \n
      1. Restart your server (Apache, Nginx, etc.)<\/li>\n<\/ol>\n\n\n\n
        3. Log Errors Instead (Safe for Live Sites)<\/h2>\n\n\n\n
        For live (production) websites, don\u2019t show errors to users. Instead, log them like this:<\/p>\n\n\n\n
        display_errors = Off
        log_errors = On
        error_log = \/path\/to\/php-error.log<\/code><\/pre>\n\n\n\n
        This keeps your site safe while you still get the error info.<\/p>\n\n\n\n
        4. Test Example<\/h2>\n\n\n\n
        <?php
        ini_set('display_errors', 1);
        error_reporting(E_ALL);

        \/\/ Intentional error
        echo $undefined_var;<\/code><\/pre>\n\n\n\n
        This will show:<\/p>\n\n\n\n
        \n
        Warning: Undefined variable…<\/p>\n<\/blockquote>\n\n\n\n
        Conclusion<\/h2>\n\n\n\n
        Showing PHP errors helps you find bugs fast. Use ini_set()<\/code> during development, and switch to logging on live sites to stay secure.<\/p>\n","protected":false},"excerpt":{"rendered":"
