Description:
------------
Same as bug #45150. I was not able to connect to MySQL via localhost though PHP found the mysql extension etc.
Finally, after 20 hours work, I found a website through Google that let me to a solution. To fix this I'll have to use "127.0.0.1" instead of "localhost"
I'm using IIS7.5 on Windows 7 Ultimate 64bit
FastCGI (PHP 5.2.13 installer [20,929Kb] - 25 February 2010, md5: 891e3262428851ebe71d5432a97be6d5, with my own php.ini aftertouch)
MySQL 5.1.46-winx64
Using both IPv4 and IPv6
I can use localhost within MySQL command prompt, but not with PHP.

Test script:
---------------
// timeout
$host = "localhost";
$user = "root";
$password = "******";
$database = "******";
$mysql_link = mysql_connect( $host, $user, $password );

// timeout fixed
$host = "127.0.0.1";
$user = "root";
$password = "******";
$database = "******";
$mysql_link = mysql_connect( $host, $user, $password );


Expected result:
----------------
Normal connection with mysql without timeout.

Actual result:
--------------
Timeout trying to connect via mysql_connect (Error: 2002)

After I updated php from 5.3.0 to 5.3.2,
mysql_connect cannot connect localhost but 127.0.0.1.
It shows:
Warning: mysql_connect() [function.mysql-connect]: [2002] A connection attempt failed because the connected party did not (trying to connect via tcp://localhost:3306) in ........

And drivers\etc\hosts seems good.

I have the same issue as falcon_ia at hotmail dot com. I upgraded 5.3.0 to 5.3.2 and php is no longer able to connect to Mysql. Mysql is working fine and my hosts file is correct.

Check if this is your case, most probably it is.
