Note on XML_Serializer Article

If you’re reading Instant XML with PHP and PEAR::XML_Serializer, there’s a small point I need to correct, related to unserializing XML into PHP objects. On page 3, about half way down, I wrote;

Like PHP’s unserialize() function, XML_Unserializer doesn’t provide a mechanism for calling class methods when unserializing objects; rather, it sets the properties of an object directly (so, be careful):

Since writing that, while trawling the source discovered that XML_Unserializer does provide a mechanism to use a method for setting object properties, by using an explicitly named method like “set“, where is the name of the object property.

--ADVERTISEMENT--

In other words, when unserializing objects, if your PHP class contains “setter methods”, following this naming convention, XML_Unserializer will use those methods instead of setting the property directly.
