Get Sharepoint data list in php - php

Question

I tried to get SharePoint list in php. Below is code
require_once __DIR__ . '\Faker-master\src\autoload.php'; //Faker library (https://github.com/fzaninotto/Faker)
require_once 'lib/SPOClient.php';
$username = 'aaaa.aaa#microsoft.com';
$password = '*******';
$url = "https://microsoft.sharepoint.com";
generateContacts($url,$username,$password);
function generateContacts($url,$username,$password){
$client = new SPOClient($url);
$client->signIn($username,$password);
$list = $client->getList('ClientMaster');
$contactsCount = 120;
for($i = 0; $i < $contactsCount; $i++){
$contactEntry = createContactEntry();
$item = $list->addItem($contactEntry);
print "Contact '{$item->Title}' has been created succesfully.\r\n";
}
}
O/p:
