MySQLI connect to local server through socket error

Question

I am receiving the below MySQLI error when I try to connect to my DB:

Warning: mysqli_connect() [function.mysqli-connect]: (HY000/2002): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /nfs/c10/h03/mnt/144844/domains/trash.mysite.com/html/functions.php on line 43 Failed to connect to MySQL: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

My connection file:

<?php $host = 'internal-db.s144844.gridserver.com'; $user = 'db144844_db'; $password = '***********'; $db = 'db144844_db'; ?>

The functions file:

`

require('connection.php');

function sendMessage($message)
{
    // this line loads the library 
    require('twilio-php-master/Services/Twilio.php'); 

    $account_sid = '***'; 
    $auth_token = '***'; 
    $client = new Services_Twilio($account_sid, $auth_token); 

    $client->account->messages->create(array( 
        'To' => "5555555555", 
        'From' => "+6666666666", 
        'Body' => $message, 

    ));
}

function resetTrash()
{
    //this could be set to just go on a certain day like tuesday
    $connection=mysqli_connect($host , $user , $password , $db);

    //turn alerts off in the db cause we missed it or whatever
    if (mysqli_connect_errno()) 
    {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    mysqli_query($connection,"UPDATE trash SET done=0 WHERE id=1");

    mysqli_close($connection);

}

function markDone()
{
    //this could be set to just go on a certain day like tuesday
    $connection=mysqli_connect($host , $user , $password , $db);

    //turn alerts off in the db cause we missed it or whatever
    if (mysqli_connect_errno()) 
    {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    mysqli_query($connection,"UPDATE trash SET done=1 WHERE id=1");

    mysqli_close($connection);

}

?>`

This is line 43 from the second function:

$connection=mysqli_connect($host , $user , $password , $db);

My host MediaTemple says that they can connect fine from their side using my connection info but a socket error seems like it would be something to do with MySQL not my code.

I can log into the DB fine using phpMyAdmin and such.

Your script is throwing several notices about undefined variables but you haven't configured PHP to display error messages. That's something you need to fix before you go further; it's impossible to code properly without the aid of error messages. Here's a [brief explanation](http://stackoverflow.com/a/5680885/13508). — Álvaro González, May 07 '14 at 16:14

You are simply forgetting function parameters:

function resetTrash(){
    $connection=mysqli_connect($host , $user , $password , $db);
                               ^^^^^   ^^^^^   ^^^^^^^^^   ^^^
                                 ?       ?         ?        ?

You want:

function resetTrash($host, $user, $password, $db){

PHP can warn you about this errors. Please read about error reporting.
