PHP 4 to the end of this year, the PHP group will no longer support it, so in order to let people more confident transfer to the PHP 5 platform, I specifically did this test, to see if our PHP 4.x is really better than our PHP 5.x pinch, the test results are obvious, that is PHP 5.x The PHP 4.x is faster than PHP 4.x for both object-oriented and process-oriented, so it's absolutely necessary to move on to the PHP 5.x platform to experience the various functions and performance of the PHP 5.x platform.
Because PHP 5 includes the new object model, more new features, faster processing speed, especially the speed of object-oriented code, although in PHP 4, object-oriented code is more common, But object-oriented code in php5.x is faster than process-oriented, so don't be skeptical about object-oriented performance, as the following test results will show.

[Result analysis]
1.Overall, can obviously just see PHP5.2 performance is slightly higher than PHP4.4, so do not suspect PHP5.2 performance will be poor, significantly faster than PHP4
2.The parsing performance of the class in PHP4.4 is significantly slower than the function, especially when inheritance is used, and the descent is much worse, so it is more appropriate to use process-oriented and non-inherited class operations in PHP4.4.
3.The result of the PHP5.2 is that the class executes faster than the function, and you can see that the PHP5.2 engine takes a lot of effort in object-oriented processing, and that they perform well in both function and class.
4.With this test, we had every reason to upgrade the PHP4 to PHP5 with little change in code, and PHP5 basically backwards-compatible PHP4 code, except for some special code. Also mentioned above the end of this year, the PHP group will no longer continue to PHP4 maintenance, so early upgrade, early peace of mind.
