PHP Appending same value to two variables

Question

I need to append a value to two variables.

$a = "String A";
$b = "String B";

...

$a .= " more";
$b .= " more";

Is there a shorter way to get this work?

$a .= $b .= " more"; is not doing what I want.

Thanks in Advance, Matty

The way you are doing is okay. And both the variable holds different values. — Sougata Bose

For two or three vars that's ok. If you have more, consider making a function. — georg

You can't do that, with this, $a="String AString B more" and $b="String B more" is there is few of var to assign, make it like your first idea, else, just create a function to assign value. — WilliamN

Not really.

$a .= $b .= " more";

Is equivalent to:

$b .= " more";
$a .= $b;

The best way is to write:

$a .= " more";
$b .= " more";

Or (if you have a lot of them) use array with some functions:

#1 - array_map approach

function addMore(&$vars) {
    $var .= " more";
}
$array = [$a, $b];
$array = array_map('addMore',$array);

#2 - classic approach:

$array = array($a, $b);
foreach ($array_before as &$var) {
    $var .= " more";
}
