从PHP输入文本字段中删除某个字符串,然后将其保存到MySQL数据库[重复]

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);
    

    See: https://secure.php.net/manual/en/function.str-replace.php
