Escaping of SQL parameters in PHP is an needlessly tedious and error-prone process. Calling the right escaping function for every parameter that might be dangerous is a difficult task in a big project. This is just dangerous and calls for SQL-Injection-Attacks.
It’s obvious we need a uniform query function that automatically does the escaping for us. Perl-style parameter binding seems to be just the right choice. You can write your query, insert placeholders in the form of
:n and pass the parameters to our function. The function automatically detects the datatype of the parameter for us and escapes it if needed.
query( 'SELECT posts FROM blog WHERE status = :2 AND created = :1', POST_STATUS_ACTIVE, '2007-08-02' );
