It solves a different problem to serialize(). serialize can take pretty much any PHP object / array / data structure and convert it into a string, but the resulting string will still need addslashes() applied to store it in a database and htmlspecialchars() for display in a hidden form field etc. The encode() function takes a PHP string and converts it into a "safe" string which can be put straight in a database / hidden form field / URL variable without needing any further processing - it can then be decoded at a later date. In fact, the encode() and decode() functions would probably complement serialize() very well :) > On Monday, February 25, 2002, at 11:27 PM, Demitrious S.
