nginx +php-cgi，apahce+php-cli，cgi的比较

一，突发神精，来把它们三儿来比较

在网上看到好多文章说nginx有多么，多么好。不管好不好，看看测试结果在说，

1，nginx＋php-cgi说明

nginx我开启了11个进程，php-cgi我开启了10个进程

2，apache＋php-cgi说明

httpd我开启了11个进程，php-cgi我开启了10个进程

3，apache＋php-cli说明

没作任何限制

二，测试文件一test.php无逻辑文件

<?php
phpinfo();
?>

1，nginx+php-cgi

三，测试文件二test1.php

<?php
$con = mysql_connect("localhost","username","password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("test", $con);
mysql_query('set names utf8');

$result = mysql_query("SELECT id, name, sex FROM test ");

while($row = mysql_fetch_array($result))
  {
  echo $row['id'] . "+" . $row['name']."+".$row['sex'];
  echo "
";
  }

mysql_close($con);
?>

1，nginx+php-cgi

四，个人分析

1，针对无逻辑文件，或者静态文件

在内存，cpu都没有最大化利用的情况下nginx＋php-cgi效果比apache+php-cli的效果好一点，而apache+php-cli是最大化用内存和cpu，由起可见，nginx＋php-cgi的对无罗辑或静态文件的解析要好很多。apache+php-cgi的效果很差，虽然php官方力挺php-cgi，但是根apache的配合效果不好。

2，针对逻辑复杂的文件

针对逻辑复杂的文件时，nginx＋php-cgi对php的解析的效果下降了，但是下降的不是很厉害。而apache＋php-cli对php的解析的效果去增强了，增加了很多，是原来的差不多1.5倍。nginx＋php-cgi在利用部分内存和CPU的情况下根apache＋php-cli对php的解析都差不了多少，个人认为。nginx＋php-cgi要比apache＋php-cli要好。但是要想达到好多好多倍，我看难。

上面所做对比，不考虑11nginx，配合10php-cgi是否合理，这个就nginx来说，肯定不是很合理的。
