PHP: is JSON or XML parser faster?
json, performance, php, xml
Solution
I didn't do any benchmark but...
Since JSON is only a description of nested string sequences, without the need to offer a DOM interface, attributes parsing and other subtle stuff, my guess is that a JSON parser is WAY faster that an XML parser.
Problem
I'm building classes that interface with the Twitter API, and I'm wondering whether PHP's built-in XML or JSON parser is faster? Twitter will send me the same data in either format, so PHP performance will determine my choice. I'm using php_apc, so you can disregard parse time and assume I'm running off bytecode. Thanks! more: I'm just looking to get associative arrays from the data. I'm not doing tree walking, node iteration or anything too complex. The format will always be the same. (I hope!)
