To specify your array as URL parameters, you need to add "[]" before "=" sign. In that way php recognizes it as array. Otherwise the value will be just a string.

/*------ Change This -------*/
var src="sent.php?sub="+multiInput.getValues()+'&sub='+sub+'&compose='+compose+'';
window.location.href=src;

/*----- To this -------*/
var src="sent.php?sub[]="+multiInput.getValues()+'&sub='+sub+'&compose='+compose+'';
window.location.href=src;

Secondly, since your 'onclick' function does not update the values of variables you've defined above; it just not get the latest value of them. To solve this issue moving variables inside the function is enough.

const getButton = document.getElementById('get');
const multiInput = document.querySelector('multi-input'); 
getButton.onclick = () => {

/*----- Define them in here -------*/
var sub = document.getElementById('sub').value;
var compose= document.getElementById('compose').value;

var src="sent.php?sub="+multiInput.getValues()+'&sub='+sub+'&compose='+compose+'';
window.location.href=src;
}
