PHP application MySQL Extension library connection to MySQL server failed

PHP failed to connect to MySQL server using MySQL extension library
It always goes wrong when PHP uses the MySQL extension library to expand the MySQL server. said that the page can not open, detailed error is not reported, I tried a few other errors will be reported! Configuration is also made in the php.ini file. You can also see MySQL in the page using the Php_info () function. It's very confusing.
Here's the statement I connected to the database:
$link =mysql_connect ("localhost:3306", "root", "123456");
if (! $link) {
Die ("error message is". Mysql_error ());
}
It's very confusing. I don't know why.
Here is the configuration in my php.ini file.
Extension_dir = "D:/php/ext"
Extension=php_msql.dll
MySQL Extended Server
