PHP 4到今年年底PHP Group将不再对其进行支持了，所以为了让大家更有信心的转移到PHP 5平台上，我特别做了这个测试，看看我们PHP 4.x 是否真的性能比我们的PHP 5.x要好捏，测试结果很明显，那就是PHP 5.x 比php 4.x不论是面向对象还是面向过程，都要比PHP 4.x 要快，所以大家完全有必要转移到PHP 5.x 平台上，去体验PHP 5.x 平台的各种功能和性能。

因为PHP 5 包括新的对象模型，更多新特点，更快的处理速度，特别是处理面向对象代码的速度，虽然在php 4中面向对象代码的速度比较一般，但是在PHP5.x中面向对象代码的速度都超过了面向过程的速度，所以不要对面向对象的性能持有怀疑，下面的测试结果将说明这一切。

【测试环境】

• CPU: Intel Pentium4 2.66GHz
• Memory: 1GB
• Disk: 73GB/SCSI
• OS: FreeBSD 4.11
• Web: Apache 1.3.37
  测试工具：ab （也可以选用http_load）
  名词RPS: Requests per second (每秒的请求数量)

【PHP 4.4.2 测试结果】

[ 函数 Function ]

function signin(){
echo “test”;
}
signin();
?>
测试结果：ab -n 10000 -c 50 的结果是1047.23/rps
[ 类 Class ]

不实例化类
class User{
function signin(){
echo “test”;
}
}
User::signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1034.98/rps
实例化类
class User{
function signin(){
echo “test”;
}
}
$user=new User();
$user->signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1006.14/rps
类的继承
class AUser{
function signin(){}
}
class User extends Auser{
function signin(){
echo “test”;
}
}
$user=new User();
$user->signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 992.95/rps

【PHP 5.2.1测试结果】

[ 函数 Function ]

function signin(){
echo “test”;
}
signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1176.06/rps
[ 类 Class ]

不实例化类
class User{
public function signin(){
echo “test”;
}
}
User::signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1197.17/rps

实例化类
class User{
public function signin(){
echo “test”;
}
}
$user=new User();
$user->signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1187.93/rps
类的继承和抽象
abstract class AUser{
abstract function signin();
}
class User extends Auser{
public function signin(){
echo “test”;
}
}
$user=new User();
$user->signin();
?>
测试结果：ab -n 10000 -c 50 的结果是 1128.54/rps

【测试结果和分析】

[ 测试结果数据 ]

版本	函数测试	不实例化类	实例化类	类的继承
PHP 4.4.2	1047.23/rps	1034.98/rps	1006.14/rps	992.95/rps
PHP 5.2.1	1176.06/rps	1197.17/rps	1187.93/rps	1128.54/rps

[Result Analysis]

1. Generally speaking, it is obvious that the performance of PHP5.2 is slightly higher than that of PHP4.4, so don’t doubt that the performance of PHP5.2 will be worse, it is obviously faster than PHP4
2. The parsing performance of classes in PHP4.4 is obviously slower than that of functions, especially when inheritance is used, it drops sharply, so it is more suitable in PHP4.4 Using process-oriented and non-inherited class operations
3. The result in PHP5.2 is that the execution speed of classes is faster than that of functions. It can be seen that the PHP5.2 engine spends a lot of time on object-oriented processing. A lot of effort, and at the same time, whether they are functions or classes, their performance is good
4. Through this test, we have every reason to upgrade PHP4 to PHP5 with little code change. Moreover, PHP5 is basically backward compatible with PHP4 code, except for some special codes. In addition, it is mentioned above that PHP Group will no longer continue to maintain PHP4 after the end of this year, so upgrade early and have peace of mind.

PS: Thanks to my colleague Jianxiang for providing some test codes
