Safely querying a MySQL database record that has quotes in it

pezholio
Hi,

I'm trying (and failing) to find a safe method that returns records from a database if they have quotes in them, for example, if I generate a query like this:

SELECT * FROM foo WHERE bar LIKE 'here's pezholio's record with quotes'

Obviously it will be unsafe as I haven't escaped the quotes. I've tried storing the records with slashes already in them and then searching ie:

SELECT * FROM foo WHERE bar LIKE 'here/'s pezholio/'s record with quotes'

Which should return a result. I've also tried HTML entities ie 'here's pezholio's record with quotes'

But neither method works! Any ideas?

You should run all strings through the mysql_real_escape_string function before adding them to a MySQL query.

It encodes all characters that may cause problems during the query, so it can be safely executed.

Alternatively, you could consider using the MySQLI Class and it's ability to use prepared statements
