How to pass value to variable and return it without calling recursive loop function?

Question

function test_loop($x_values,$x, $y)
{
    $x = $x + 1;
    if($x < 4)
    {
        //I want to add $x value into $x_values variable, eg : $x_values = $x_values . $x

Why don't you try to make $x_values an array, and add values in $x_values as array items, $x_values[] = $x; and then when you're ready, just implode() those values into a string. Like this:

function test_loop($x_values,$x, $y)
{
    $x = $x + 1;
    if($x < 4)
    {
        $x_values[] = $x;
    }

//loop again if y is not = 3;
$y = $y + 1;
if($y < 3)
{
    echo "kkk" . $y . "<br/>";
    $x_values[] = $x;
}else{
    echo "---------------------<br/>";
}

return implode($x_values); 
}

Just make sure that you also pass $x_values as an array initially:

function abc(){
    $bababa = test_loop([0],1,0);

    echo $bababa;
}
