$x = mysql_real_escape_string($x);

$sql = "INSERT INTO mytable ( name ) VALUES ( '$x')";

Man page here:
http://us.php.net/manual/en/function.mysql-real-escape-string.php

The value inside $x contains an apostrophe, so it must be escaped for use in queries.  Instead of trying to replace just the apostrophe, it's always wisest to use the recommended PHP function that handles all the necessary escape sequences.

Just for single quotes to two
$x='mary\'s address';
$x = str_replace("'", "''", $x);

Open in new window

But for insertion to DB, Ray's comment on using mysql escape is gold

On other thought... If you're working with data bases, you might want to post your questions in both the PHP and the PHP and Databases Zones.  You can use up to three Zones for any question.  If you add the MySQL Server Zone to those other two, you will get more expert eyes on your questions.

Best regards, over and out, ~Ray
