Checking if string contains numbers

Ways to load an array from file into a variable: 1- $var = require ‘myarray.php’; // or include // myarray.php contents return array(“test”,”test2″); 2 – require ‘myarray.php’; // or include // myarray.php contents $var = array(“test”,”test2″); Use $var as you would normally. 3- $var = file_get_contents(‘myarray.php’); // myarray.php contents array(“test”,”test2″);
