Introduction to the incorrect configuration method of php connection to mysql_PHP tutorial

This article will introduce to PHP beginners the solution to the prompt Call　to　undefined　function　mysql_connect() when connecting to mysql after PHP is configured.

First, let’s test the php connection to mysql according to the book

Baidu found that the PHP+MYSQL environment is not configured properly, and the default mysql of php5 is closed

The code is as follows

代码如下	复制代码
$link=mysql_connect('localhost','root','123456'); if(!$link) echo "失败!"; else echo "成功!"; mysql_close(); ?>

Copy code

$link=mysql_connect('localhost','root','123456'); if(!$link) echo "Failed!";

else echo "Success!";

mysql_close(); ?>

Running the code appears:

Call　 to　 undefined　 function　 'mysql_connect()'…

Error failed

Copy the php_mysql.dll and libmysql.dll files to c:/winnt/system32 (I missed libmysql.dll)

Find ;extension=php_mysql in php.ini and remove the ";" in front of it
