Fatal error: Call to undefined function mysql_connect() 以及使用PHPINFO()没有MYSQL的信息。PHP.ini文件：
extension_dir = "D:/Server_Core/PHP/ext"extension=php_mysql.dll
extension=php_pdo_mysql.dll
另外PHP安装目录里的libmysql.dll也复制到了System32里面
请问怎么做才可以让PHP连接MYSQL？

请问怎么做才可以让PHP连接MYSQL？
PHP的版本
MYSQL的版本
---------
最新的php5.3.5 使用 mysqlnd 根本不需要 libmysql.dll
建议用php5.3.x的版本
MYSQL的是5.0的版本初次学习，请多指教
php_mbstring.dll
php_mysql.dll
php_gd2.dll
libmhash.dll
libmcrypt.dll
这些也都拷贝到另System32文件夹里面去了。
MYSQL安装了之后，我单独测试正常
现在的问题就是PHP与MYSQL之间没有联系起来。。
另外在phpinfo里面没有MYSQL的信息
确认一下mysql能开启吗?看看以前总结的。wamp基本配置：
首先介绍php的配置，在解压后的文件夹中找到php.ini，打开并找到 ；extension=php_mysql.dll，将它前面的“；”去掉，找到extension_dir = "./" 改为 extension_dir = "php安装目录/ext"之后保存并把php.ini拷贝到windows目录下，把php/php5ts.dll 拷贝到windows文件夹下，把php/libmysql.dll 拷贝到system32下就OK了。接着我们来配置一下apache，在它的安装目录下进入到conf文件夹，打开httpd.conf文档，该文档记录了apache的相关配置，首先找到Documentroot，把你所要建立的web目录的路径拷贝到document下，例如我在D盘先建立一个webroot文件夹，所以Documentroot”D:/webroot”,在这里要注意httpd.conf中要将“\”变为“/”，同时不要忘记在document那行的下面<Directory></Directory> 设置为<Directory “D:/webroot”>,并将Options 和AllowOverride后面的参数设置为All，注意大小写。在该文档的任何位置添加LoadModule php5_module “php的安装目录/php5apache2_2.dll”和Addtype application/x-httpd-php .php（apache能识别.php文件），之后找到LoadModule rewrite_module modules/mod_rewrite.so，将它前面的“；”去掉，保存重启Apache。最后关于mysql的配置，这个配置很简单，大家在配置过程中按他的提示进行选择填写就OK了，其一个问题就是大家可以在我的电脑右击，选择属性，点击高级选项卡，进入环境配置，将Path路径中添加你mysql的bin文件夹的系统路径，变量值如：C:\Program Files\MySQL\MySQL Server 5.0\bin，注意不要忘记要用“；”隔开，点确定就OK了，这样我们在命令行下就可以直接运行mysql了，不用在切换到bin文件下。测试：
在配置过程中，我将d盘下的webroot文件夹作为我网站开发的跟目录。打开浏览器，在地址栏输入http://www.localhost.com，配置成功的话会在页面上显示It works 说明apache已经配置成功了，我们在webroot下建立一个test.php ，用我们最熟悉的hello world语句来测试，<?php echo “hello，world！”;?> ,之后我们在浏览器地址栏输入http://www.localhost/text.php，在页面显示 hello,world！我们打开运行，在命令行下输入Mysql –h localhost –u root –p 回车后让你输入密码，输入你在配置mysql的密码回车后，显示
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.0.18-nt
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
index.php
<?php
$link=mysql_connect('localhost','root','123456');
if(!$link) echo "fail";
else echo "success";
mysql_close();
?>
应该是一个叫libmysql.dll文件的问题
你找一下 php和mysql里面应该各有一个 两个冲突了
你把一个移动到别的文件夹里面去 具体哪个你自己试下 system32下面的也记得改下
Apache显示简单的 echo 出来的东西没有问题
MYSQL单独测试，创建表都OK的
所以是说PHP与MYSQL没有联系。恩 有两个libmysql。dll
现在的问题的是一个是PHP的，另外一个是MYSQL的，请问怎么拷贝？？？？
难道要PHP连接已个MYSQL都这么复杂吗
另外这些dll的话，我不仅是在环境变量里面设置了，而且还复制到System32文件夹里了安装的是单独的，没有用那种集成的恩 谢谢 也不可用
一般来说 你apache和mysql单独运行没问题的话 只是程序不能连接数据库
通常都是ini配置文件 和 libmysql.dll的问题
你把这两个地方再仔细查下 还不行的话 重装吧 有可能是你装的时候某个地方配置有误
PHP和MYSQL是可以单独跑起来
PHP.ini配置文件如下：;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior. In order for PHP to
; read it, it must be named 'php.ini'. PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory. The
; path in which the php.ini file is looked for can be overridden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple. Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
; foo = ; sets foo to an empty string
; foo = none ; sets foo to an empty string
; foo = "none" ; sets foo to the string 'none'
;
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
;
;
;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This is the recommended, PHP 5-style version of the php.ini-dist file. It
; sets some non standard settings, that make PHP more efficient, more secure,
; and encourage cleaner coding.
;
; The price is that with these settings, PHP may be incompatible with some
; applications, and sometimes, more difficult to develop with. Using this
; file is warmly recommended for production sites. As all of the changes from
; the standard settings are thoroughly documented, you can go over each one,
; and decide whether you want to use it or not.
;
; For general information about the php.ini file, please consult the php.ini-dist
; file, included in your PHP distribution.
;
; This file is different from the php.ini-dist file in the fact that it features
; different values for several directives, in order to improve performance, while
; possibly breaking compatibility with the standard out-of-the-box behavior of
; PHP. Please make sure you read what's different, and modify your scripts
; accordingly, if you decide to use this file instead.
;
; - register_long_arrays = Off [Performance]
; Disables registration of the older (and deprecated) long predefined array
; variables ($HTTP_*_VARS). Instead, use the superglobals that were
; introduced in PHP 4.1.0
; - display_errors = Off [Security]
; With this directive set to off, errors that occur during the execution of
; scripts will no longer be displayed as a part of the script output, and thus,
; will no longer be exposed to remote users. With some errors, the error message
; content may expose information about your script, web server, or database
; server that may be exploitable for hacking. Production sites should have this
; directive set to off.
; - log_errors = On [Security]
; This directive complements the above one. Any errors that occur during the
; execution of your script will be logged (typically, to your server's error log,
; but can be configured in several ways). Along with setting display_errors to off,
; this setup gives you the ability to fully understand what may have gone wrong,
; without exposing any sensitive information to remote users.
; - output_buffering = 4096 [Performance]
; Set a 4KB output buffer. Enabling output buffering typically results in less
; writes, and sometimes less packets sent on the wire, which can often lead to
; better performance. The gain this directive actually yields greatly depends
; on which Web server you're working with, and what kind of scripts you're using.
; - register_argc_argv = Off [Performance]
; Disables registration of the somewhat redundant $argv and $argc global
; variables.
; - magic_quotes_gpc = Off [Performance]
; Input data is no longer escaped with slashes so that it can be sent into
; SQL databases without further manipulation. Instead, you should use the
; database vendor specific escape string function on each input element you
; wish to send to a database.
; - variables_order = "GPCS" [Performance]
; The environment variables are not hashed into the $_ENV. To access
; environment variables, you can use getenv() instead.
; - error_reporting = E_ALL [Code Cleanliness, Security(?)]
; By default, PHP suppresses errors of type E_NOTICE. These error messages
; are emitted for non-critical errors, but that could be a symptom of a bigger
; problem. Most notably, this will cause error messages about the use
; of uninitialized variables to be displayed.
; - allow_call_time_pass_reference = Off [Code cleanliness]
; It's not possible to decide to force a variable to be passed by reference
; when calling a function. The PHP 4 style to do this is by making the
; function require the relevant argument by reference.
; - short_open_tag = Off [Portability]
; Using short tags is discouraged when developing code meant for redistribution
; since short tags may not be supported on the target server.
; Language Options ;
;;;;;;;;;;;;;;;;;;;;; Enable the PHP scripting language engine under Apache.
engine = On; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
zend.ze1_compatibility_mode = Off; Allow the <? tag. Otherwise, only <?php and <script> tags are recognized.
; NOTE: Using short tags should be avoided when developing applications or
; libraries that are meant for redistribution, or deployment on PHP
; servers which are not under your control, because short tags may not
; be supported on the target server. For portable, redistributable code,
; be sure not to use short tags.
short_open_tag = Off; Allow ASP-style <% %> tags.
asp_tags = Off; The number of significant digits displayed in floating point numbers.
precision = 14; Enforce year 2000 compliance (will cause problems with non-compliant browsers)
y2k_compliance = On; Output buffering allows you to send header lines (including cookies) even
; after you send body content, at the price of slowing PHP's output layer a
; bit. You can enable output buffering during runtime by calling the output
; buffering functions. You can also enable output buffering for all files by
; setting this directive to On. If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).
output_buffering = 4096; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to "mb_output_handler", character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
; is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
; and you cannot use both "ob_gzhandler" and "zlib.output_compression".
; Note: output_handler must be empty if this is set 'On' !!!!
; Instead you must use zlib.output_handler.
;output_handler =; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary due to nature of compression. PHP
; outputs chunks that are few hundreds bytes each as a result of
; compression. If you prefer a larger chunk size for better
; performance, enable output_buffering in addition.
; Note: You need to use zlib.output_handler instead of the standard
; output_handler, or otherwise the output will be corrupted.
zlib.output_compression = Off
;zlib.output_compression_level = -1; You cannot specify additional output handlers if zlib.output_compression
; is activated here. This setting does the same as output_handler but in
; a different order.
;zlib.output_handler =; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block. This is equivalent to calling the

serialize_precision = 100; Whether to enable the ability to force arguments to be passed by reference
; at function call time. This method is deprecated and is likely to be

; declaration. You're encouraged to try and turn this option Off and make
; sure your scripts work properly with it in order to ensure they will work
; with future versions of the language (you will receive a warning each time
; you use this feature, and the argument will be passed by value instead of by
; reference).
allow_call_time_pass_reference = Off;
