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");
