connect function mysql php undefined windows exist hint connect

Today I configured the php mysql environment in windows. I am very happy to test a piece of code and the result prompts Call to undefined function mysql_connect(), which proves that the database configuration was unsuccessful.

1. Copy the two files libmysql.dll and php5ts.dll in the php folder to system32 in the windows directory; or add D:php;D:phpext to the environment variables. These two directories are the PHP installation directory and the extension dll directory.
The code is as follows
 代码如下 复制代码

$conn = mysql_connect('localhost','root','password');

var_dump($conn);

?>

Copy code

$conn = mysql_connect('localhost','root','password');

var_dump($conn);

?>

 代码如下 复制代码

extension=php_mysql.dll
extension=php_mysqli.dll把前面的分号去掉


Basically change the configuration file php.ini

First make sure extension_dir = "./ext" in php.ini, this setting is the directory where php refers to the dll;
2. Modify php.ini in the windows installation directory and remove the semicolon in front of extension=php_mysql.dll; 3.extension_dir = "d:phpext (the file is in PHP.INI).

Look at the configuration of your php.ini and find it
