endif

Endif is a keyword used to mark the end of an if-block in several programming languages and templating syntaxes. It serves to close a conditional block that began with an if statement, and its exact form and placement can vary by language.

In PHP, end if is part of the alternative syntax for control structures, often used when embedding PHP in HTML. The form uses a colon after the if condition and closes with endif;, ending the block. For example:

<?php if ($a > $b): ?>

<?php endif; ?>

This syntax is common in templates and older PHP code where readability within HTML is important. The regular brace-based syntax in PHP uses if (...) { ... } and does not require endif.

Beyond PHP, similar closing constructs appear in template languages that embed programming logic within markup. In Twig and Django templates, for instance, conditional blocks open with {% if condition %} and close with {% endif %}. These languages use the end tag to indicate the conclusion of the conditional block, separate from the surrounding template syntax.

Overall, endif functions as a language- or framework-specific way to terminate an if block, with the exact requirements (such as semicolons or closing tags) dependent on the surrounding syntax. It is not a universal keyword across all programming languages, but a recognized convention in environments that employ alternative or templating syntax for control structures.
