PHP reading config data from json file

config.json, the json config file can store the database login info or some webservice api login info or any other system configuration data.

{
	"database" : {
		"host" : "localhost",
		"user" : "ken",
		"password": "123456",
		"dbname":"ecom"
	},
	"webservice1":{
		"api_key": "kD3l@gs56jsDG#s9@Fgj4839",
		"api_secret": "SG353Ge245gVw3Ht3eye@309pDeg"
	},
	"webservice2":{
		"api_key": "DG3dfsg3@gs9@Fgj4ddh$drg",
		"api_secret": "DplR9ne245HfBEw#HNs0dsfh"
	}
}

connect.php, the php file can read the data from the json file, convert it to php std object, and use these data as you needed.

<?php
$jsonStr = file_get_contents("config.json");
$config = json_decode($jsonStr); // if you put json_decode($jsonStr, true), it will convert the json string to associative array
echo var_dump($config);

$con = mysqli_connect(
	$config->database->host, 
	$config->database->user, 
	$config->database->password,
	$config->database->dbname
	);
if (mysqli_connect_errno())
{
  echo "Failed to connect to the database: ".$config->database->dbname. mysqli_connect_error()."\n";
}
else
{
	echo "connected to database ".$config->database->dbname."\n";
}
exit("done");
