Magic quotes GPC is a PHP feature designed to help protect developers from SQL injection attacks. It automatically adds slashes to all data received via GET, POST, or COOKIE. However, this protection is not perfect and can be inconsistent, as it doesn't cover all special characters interpreted by databases. Additionally, data not sent directly to databases must be unescaped before being used. Due to its limitations, it's not recommended to enable magic_quotes_gpc. Instead, it's better to implement proper input filtering and validation in your PHP scripts to protect your databases and website.
Here's how to enable or disable magic quotes GPC for your PHP scripts:
Step 1: Log in to your FTP account
Log in to your FTP account using an FTP client.
Step 2: Modify the .htaccess file
Locate and open the .htaccess file in your website's root directory (usually the "html" or "public_html" folder).
To disable magic_quotes_gpc, add the following code to your .htaccess file:
# Disable magic_quotes_gpc
php_flag magic_quotes_gpc off
If your PHP script requires magic_quotes_gpc to be enabled, you can enable it by adding the following code to your .htaccess file:
# Enable magic_quotes_gpc
php_flag magic_quotes_gpc on
Step 3: Handle 500 Internal Server Error
If you encounter a 500 internal server error after adding the above settings to your .htaccess file, remove the settings from the file and add the following code to your PHP file instead:
