PHP String Concat Options

test.php

<?php

$speed = ['quick', 'slow'];
$animal = ['rabbit', 'turtle'];

// Typical String Concatenation
$string = 'The ' . $speed[0] . ' ' . $animal[1] . ' jumped over the fence';

// Breaking on Concatenation operator BEFORE the line exposes in each new line
// we're able to easily skim down the file and see we're concatenating. Also
// makes the variables easier to human parse
$string = 'The ' 
    . $speed[0] 
    . ' ' 
    . $animal[1] 
    . ' jumped over the fence';

// Breaking on Concatenation operator AFTER the line:
// IMHO this is harder to human parse/lint
// This does also make the vars easy to read
$string = 'The ' .
    $speed[0] .
    ' ' .
    $animal[1] .
    ' jumped over the fence';
