How can PHP handle escaping magic_quotes_gpc, decoding HTML entities, and converting special characters in form inputs?

To handle escaping magic_quotes_gpc, decoding HTML entities, and converting special characters in form inputs, you can use PHP functions like stripslashes(), html_entity_decode(), and htmlspecialchars(). These functions help sanitize user input and prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. 

// Handle escaping magic_quotes_gpc, decoding HTML entities, and converting special characters in form inputs
if (get_magic_quotes_gpc()) {
    $_POST = array_map('stripslashes', $_POST);
    $_GET = array_map('stripslashes', $_GET);
    $_COOKIE = array_map('stripslashes', $_COOKIE);
}

// Decode HTML entities
$_POST = array_map('html_entity_decode', $_POST);
$_GET = array_map('html_entity_decode', $_GET);
$_COOKIE = array_map('html_entity_decode', $_COOKIE);

// Convert special characters in form inputs
$_POST = array_map('htmlspecialchars', $_POST);
$_GET = array_map('htmlspecialchars', $_GET);
$_COOKIE = array_map('htmlspecialchars', $_COOKIE);
