Single Quotes in Oracle Queries

Before we go about writing new functions to handle single quotes for our Phorum reengineering project, I need to know if there is a way for PHP to easily handle the issue of passing strings to a PL/SQL script, which requires that single quotes be doubled up: that "I don't know" is properly translated into "I don''t know". In my dreams, this is handled by OCIParse or even OCIExecute, but I have a sinking feeling that this isn't the case, and that we'll need to do an extra parsing step for all of our strings that are inserted into the database, just for single quotes.
