Loop through variables with common name

Question

At first glance I think you can get what I\'m trying to do. I want to loop though variables with the same name but with a numerical prefix. I also had some confusion about t

Answer 1

It's generally frowned upon, since it makes code much harder to read and follow, but you can actually use one variable's value as another variable's name:

$foo = "bar";
$baz = "foo";

echo $$baz; // will print "bar"

$foofoo = "qux";
echo ${$baz . 'foo'}; // will print "qux"

For more info, see the PHP documentation on variable Variables.

However, as I already mentioned, this can lead to some very difficult-to-read code. Are you sure that you couldn't just use an array instead?

$hello = array(
    "hello1",
    "hello2",
    // ... etc
);

foreach($hello as $item) {
    echo $item . "
";
}
