Local dev environment, php & mysql work, but not together

I've spent the whole day trying to set up development environment using:

• PHP Version 5.3.3
• apache 2.2
• mySQL Server 5.1
• Windows 7

The localhost renders the php fine, and I can work with mySQL via the command line client, but whenever I try to interact with mySQL through PHP I get a 30 second "waiting for localhost" and then a blank white browser.

• I've tried running tests scripts that just connect to the database.
• I've tried loggin-in via phpMyAdmin using 'root' and the correct password.
• The mySQL service IS running.
• No entries in the server error-log associated with the failed connection.
• I have the line "extension=php_mysql.dll" in my php.ini file and when I run "phpinfo()" all the mySQL information shows up.
• ".../php" and ".../MySQL Server 5.1/bin" are included in my PATH.

I basically followed the instructions here to set the whole thing up. I've tried everything I can think of twice so any fresh ideas would be greatly appreciated.

This is the code I'm using to connect to the database:

    <?php

# Define MySQL Settings
define("MYSQL_HOST", "localhost");
define("MYSQL_USER", "root");
define("MYSQL_PASS", "devpass");
define("MYSQL_DB", "test");

$conn = mysql_connect("".MYSQL_HOST."", "".MYSQL_USER."", "".MYSQL_PASS."") or die(mysql_error());
mysql_select_db("".MYSQL_DB."",$conn) or die(mysql_error());

$sql = "SELECT * FROM test";
$res = mysql_query($sql);

while ($field = mysql_fetch_array($res))
{
$id = $field['id'];
$name = $field['name'];

echo 'ID: ' . $field['id'] . '<br />';
echo 'Name: ' . $field['name'] . '<br /><br />';
}
?>

It's strait out of the example from the link I poste开发者_如何学Cd. 'test' is a valid DB.

try using WAMP or XAMPP

I'm not sure what the problem was, but I started over using the directions from www.webdevelopersnotes.com and was able to get it all working.

Happy Day!

Anybody else looking to go through the set up I would suggest following these directions. They seem to be the most up to date and explain a lot more "why" than the other sites I found.

This is a problem with the default hosts file in windows 7 (or with MySQL's lack of IPv6 support). You will need to replace the IPv6 loopback with an IPv4 loopback instead.

Open C:\Windows\System32\drivers\etc\hosts with admin privileges (if necessarily, you can temporarily de-protected it).

Find IPv6: ::1 localhost

Change to IPv4: 127.0.0.1 localhost
