PHP connection mysql prompts Call to undefined function mysql_connect()_PHP tutorial

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).
