PHP mysql_connect () Unsupported Solution _php Tutorial

Mysql_connect () function is a PHP and MySQL database connection function, if your PHP does not support mysql_connect () function is your database can not be connected with MySQL, let me summarize the solution mysql_connect () Methods that cannot be used.

If it is Apache environment, we refer to the following ways to solve

One, in the system system32 (C:/WINDOWS/SYSTEM32) directory is missing Libmysql.dll file, the solution is to find the PHP directory Libmysql.dll, and copy Libmysql.dll to c:/windows/ System32 directory, and then restart the Web service.

Second, in the php.ini file under the C:/windows directory, there is no “; extension=php_mysql.dll” in front of a “; ” remove, so can not use the corresponding function, the workaround is to open the php.ini file found; Extension=php_mysql.dll Change to

Extension=php_mysql.dll//Remove the front; make it effective

Third, the MySQL directory does not have read permissions, the correct directory permissions are as follows:

Administrator Full Control
System Full Control
Users Read and run + List folder Directory + read
Remove all other user rights, and then restart the MySQL service and Web service
(Note: The above settings have no security settings; recommend that you restart the server after modifying)
It is important to check the permissions of the php.ini file, check the permissions of the PHP files copied to the System32, and check the permissions of the PHP installation directory folder. At a minimum, you must have the users default permissions. The Temp folder must have at least the Users group modify level permissions.
However, all the methods have been tried, or failed to solve, so I searched for a bit mysql_connect () does not support,
Save the following code as phpinfo.php:

<?phpphpinfo ();? >
