Answer 1

Yeah, you can do this. Multiple ways:

1. PDO - that's the best option actually. Study this topic in the PHP manual as this can be a lot more help than just protecting your MySQL queries in PHP from breaking.
2. addslashes() - adds slashes to escape characters. This won't break your MySQL query for sure.
3. mysql_real_escape_string()
4. mysql_escape_string()

EDITED Emphasized PDO as compared to the previous version of this answer as PDO is far more safer than the other options and there is a lot more to it which can be used while working with PHP and MySQL.
