Question

I am creating a php restful API and currently I have the database connection information in each function.

//Connect To Database
    $hostname=host;
    $username=username;
    $password=password;
    $dbname=dbname;

    mysql_connect($hostname, $username, $password) OR DIE('Unable to connect to database! Please try again later.');
    mysql_select_db($dbname);
mysql_query($sqlApiAccess) or die('Error, insert query failed');

What is the best way of doing this, Can I have one database connection per php file? Or do I need to do it per function that uses the database.

Answer 1

Create a config.php And add the code:

config.php:

$hostname = 'host';
$username = 'username';
$password = 'password';
$dbname   = 'dbname';

$conn = mysqli_connect($hostname, $username, $password) OR die('Unable to connect to database! Please try again later.');
mysqli_select_db($conn, $dbname);

Then in any file you wish to use mysql, add the following:

script2.php

<?php
require_once 'config.php';

mysqli_query($sqlApiAccess) or die('Error, insert query failed');
?>
