一次php gd库引发的问题

突然发现用的好好的GD库挂了，于是就在网上找了个代替的，开始的时候没注意下了个64（安装的是32位的）的不能用，于是找个32的也不能用我的版本是5.4.28，网上找好久没找到，最终找了一个31的，发现还是不能用，没办法只好重装了，因为Apache是连接php和mysql的关键所以问题可能出在这里，还好之前下载的Apache还在版本为2.2.25，于是就配置31来安装，首选卸载Apache，卸载完把剩余的文件夹删除，最好重启一下机器，开始安装，一路回车，非常幸运没出现问题，默认Apache启用的是80端口，这里一般容易出问题，如果出现先忽略，安装完了再httpd.conf文件里找到监听端口，修改一下端口号，例如Listen 8080，开启Apache

开始配置文件，打开httpd.conf文件

将下面的代码添加进去注意斜杠问题和安装的文件夹地址

LoadModule php5_module "D:/wamp/php5/php5apache2_2.dll"  

AddType application/x-httpd-php .php

 #LoadModule PHPIniDir "D:/wamp/php5/php.ini"

#

# This is the main Apache HTTP server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.

# In particular, see 

# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

# for a discussion of each configuration directive.

#

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned.  

#

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path.  If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so 'log/access_log'

# with ServerRoot set to '/www' will be interpreted by the

# server as '/www/log/access_log', where as '/log/access_log' will be

# interpreted as '/log/access_log'.

#

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").

# If a drive letter is omitted, the drive on which httpd.exe is located

# will be used by default.  It is recommended that you always supply

# an explicit drive letter in absolute paths to avoid confusion.

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to point the LockFile directive

# at a local disk.  If you wish to share the same ServerRoot for multiple

# httpd daemons, you will need to change at least LockFile and PidFile.

#

ServerRoot "D:/wamp/apache"

#

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

#

# Change this to Listen on specific IP addresses as shown below to 

# prevent Apache from glomming onto all bound IP addresses.

#

#Listen 12.34.56.78:80

Listen 8080

# Dynamic Shared Object (DSO) Support

#

# To be able to use the functionality of a module which was built as a DSO you

# have to place corresponding `LoadModule' lines at this location so the

# directives contained in it are actually available _before_ they are used.
