concat a for loop – php

by

You first have to initialize your string :

$stringd = "xxx";

Then, loop, concatenating at the end of that variable :

for($i=1;$i<=$_POST['cc'];$i++) {
    $stringd .= $_POST[$i]." ";
}

And, finally, end with the last part :

$stringd .= "hello";

But you cannot do all (especially, the loop) that in a single operation.
