How can one check and modify the status of magic_quotes_gpc in the php.ini file to troubleshoot issues with unwanted character additions in PHP code?

Unwanted character additions in PHP code can be caused by the magic_quotes_gpc setting in the php.ini file. To troubleshoot this issue, you can check and modify the status of magic_quotes_gpc in the php.ini file by setting it to Off. This will prevent PHP from automatically adding slashes to incoming data, which can cause unwanted character additions in your code.

// Check and modify the status of magic_quotes_gpc in the php.ini file
if (get_magic_quotes_gpc()) {
    ini_set('magic_quotes_gpc', 'Off');
}
