mysql_real_escape and/or strip_tags ?
Let's say I want to write content from a form (textarea in this case) to a database.
I'm allready using mysql_real_escape_string to prevent some hacking. Is it necessary to use strip_tags(trim()) as well on the textarea?
I'm not sure if they do the same.

mysql_real_escape_string() will put a \ before all characters that could be dangerous / end & restart a SQL statement.
Both can be used for security however they serve entirely different purposes.
You would use mysql_real_escape_string() to protect your sql statement so that an attacker can't inject their own commands into your sql statement.
