学php开发，首先是要把环境给搭建起来，然后再写出自己的第一个"helloworld"小程序。

那么怎样搭建php开发环境呢？

我是这么做的：

1.下载工具：WAMP5-v1.7.4.rar

下载地址是：

下载后，解压,得到：wamp5_1.7.4.exe安装文件。双击它，就可以安装了。

它里面集成了Apache，mysql，php等开发所需的工具。安装完成后，只需要配置一些东西就可以了。

如：mysql的端口号，Apache服务器的端口号等等，如果你的机器上面没有安装过mysql，那么端口号

的配置就可以不用管他了；如果你机器上面没有安装过tomcat服务器，那么也没有必要去配置Apache服务器的

端口号。这时候，那可以直接进入开发状态。

下面是我机器上的mysql配置：

下面是我机器上的Apache的配置： 有些开发者在第一次配置apache服务的时候，老是启动不了Apache服务器，大多数原因是因为apache的端口号被占用了

解决的办法是：修改端口号，如下面我的端口号就修改为"2000"

1 #  2 # This is the main Apache HTTP server configuration file.  It contains the  3 # configuration directives that give the server its instructions.  4 # See 
      for detailed information.  5 # In particular, see   6 # 
     
        7 # for a discussion of each configuration directive.  8 #  9 # Do NOT simply read the instructions in here without understanding 10 # what they do.  They're here only as hints or reminders.  If you are unsure 11 # consult the online docs. You have been warned.   12 # 13 # Configuration and logfile names: If the filenames you specify for many 14 # of the server's control files begin with "/" (or "drive:/" for Win32), the 15 # server will use that explicit path.  If the filenames do *not* begin 16 # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" 17 # with ServerRoot set to "C:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the 18 # server as "C:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log". 19 # 20 # NOTE: Where filenames are specified, you must use forward slashes 21 # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). 22 # If a drive letter is omitted, the drive on which Apache.exe is located 23 # will be used by default.  It is recommended that you always supply 24 # an explicit drive letter in absolute paths, however, to avoid 25 # confusion. 26 # 27  28 # ThreadsPerChild: constant number of worker threads in the server process 29 # MaxRequestsPerChild: maximum  number of requests a server process serves 30 ThreadsPerChild 250 31 MaxRequestsPerChild  0 32  33 # 34 # ServerRoot: The top of the directory tree under which the server's 35 # configuration, error, and log files are kept. 36 # 37 # Do not add a slash at the end of the directory path.

2，写自己的第一个php小程序

环境搭建好了，就可以写自己的第一个php小程序了

开发工具的选择：

　　有很多开发工具可供你选择：EditPlus，记事本，eclipse for php等等

在这里我推荐使用：eclipse-php-helios-win32.zip

下载地址：

这对有java开发经验的同志来说应该是好事儿.....

下面是我的第一个php小程序：helloworld.php

在浏览器的地址栏上面输入：

运行效果：

helloworld!
