I know there is a way to check if a string contains another string using the 'REGEXP' command in SQL; however, is there a way to check if a string is contained in another string? I'm trying to build a sessions system in PHP but I want to perform different actions for bots since they don't accept cookies. To do this, I want to check a portion of the browser agent ($_SERVER['HTTP_USER_AGENT']). Unfortunately it isn't always the same so I'd rather put the regex in the database instead of PHP.
In short, I'm looking for the reverse solution to this:
SELECT bot_user_agent FROM ' . BOTS_TABLE . ' WHERE bot_user_agent REGEXP "/' . $_SERVER['HTTP_USER_AGENT'] . '/"
Problem with the above query is it checks for the entire user agent within the bot_user_agent column which isn't what I want to achieve. I want to check if the value in the bot_user_agent column is contained in the $_SERVER['HTTP_USER_AGENT'] variable; or example: the value in bot_user_agent column could be 'Googlebot' and it checks for 'Googlebot' in $_SERVER['HTTP_USER_AGENT']. This can be achieved in PHP using the preg_replace() function but only if the table contains one value (otherwise it picks up the first/last value, depending on the loop). I'd rather do it in SQL.
Hope this makes sense and thanks for your help in advance. :)
