mysqli Connection Errors in PHP

[Frank Sellers]

Hello,

I have some php code in which I am query records out of the database. I can run it and it works fine. But I have noticed that whenever I run it multiple times in a short period of time that I am receiving the following error message:

Can't connect to MySQL server on 'localhost' (10048)
The Error Number returned is 2003

Here is the code that I am using in PHP:
$this->link = new mysqli(localhost, $user, $password, $DB);

if (mysqli_connect_errno())
{
printf("Connect failed: %s\n", mysqli_connect_error());
echo "Error Number: " . mysqli_connect_errno() . "<br>";
}

I am always connecting throught the localhost, and it always uses the same username and password to access the database. It will run through a couple of times, and then I will start receiving the error message stated above. My initial thought is that I have too many connections open at the same time. I looked in my php.ini file and the max connections is set to -1, which is unlimited. Anyone else have any other ideas?

Thanks,

Frank
