PHP Shorthand for Pre-Concatenation?

Question

I've been programming in PHP for years, and I've always wondered if there is a way to 'pre-concatenate' a string. Example:

$path = '/lib/modules/something.php';
$server = $_SERVER['DOCUMENT_ROOT'];

I've been doing this for years in order to append a value to the beginning of a string:

$path = $server . $path;
// returns: /home/somesite.com/public_html/lib/modules/something.php

Is there a shorthand for this? Just curious.

Answer 1

try out the sprintf function as it has worked for me - information on it here http://docs.php.net/sprintf

Answer 2

No, but you could write your own function:

function pc(&$a, &$b) {
    $a = $b . $a;
}
pc($path, $server);

The above call to pc will set $path to $server . $path.

Answer 3

A not so serious answer (I know it is longer):

$path = strrev($path);
$path .= strrev($_SERVER['DOCUMENT_ROOT']);
$path = strrev($path);

There is no limit to creativity! ;)

Answer 4

a shorthand for concatenation is interpolation

  $path = "{$_SERVER['DOCUMENT_ROOT']}/lib/modules/something.php";
