One Liner

A one-liner refers to a concise and often single expression that accomplishes a specific task. It’s a shorthand way of expressing functionality in a compact form.

One liner are supposed to fit on one line. The line is also supposed to be limited in size.

One liners tends to pack a lot of operations in one expression. When used aggressively, one liners become less readable, and more complex.

Some commands have a short and a long syntax, such as if-then-else and the ternary operator condition ? then : else.

<?php

if ($condition) {
     doSomething();
} else {
     doSomethingElse();
}

$condition ? doSomething() : doSomethingElse();

?>
