This question already has an answer here:

What I want to achieve: I want to use a simple PHP form to send data to a MySQL database. However, when the input contains a certain string, I want to remove it before it is saved in the MySQL database.

Example: input is 'https://www.google.com', but I want to remove the 'https://' part, so only 'www.google.com' is saved in the database.

    You can use str_replace() to remove the parts you don't want:

    $input = 'https://www.google.com';
    $replaced = str_replace('https://', '', $input);
    echo $replaced;

    If you want to replace multiple values in one pass, you also do that (this will remove http://, https:// and ftp://):

    $unwanted  = array("http://", "https://", "ftp://");
    $replace   = array("", "", "");
    $replaced = str_replace($unwanted, $replace, $input);
