1.2.212. Conditional Structures¶
Structures that are defined, but only executed conditionally.
It is possible to create conditioned functions, classes, interfaces, traits and enumerations. Constants have to be defined with define() and can’t use the const keyword.
Classes elements, such as methods, can’t be conditional.
<?php
if (!function_exists('array_column')) {
function array_column($a) {
// some PHP
}
}
if (!class_exists('foo')) {
class foo {
}
}
?>
