Open Tag¶

PHP commands are placed between the PHP tags : <?php and ?>. The first tag is called the open tag.

The open tag is mandatory for PHP to execute the code. Anything before the open tag is output as is, without modification.

There is another open tag, called echo tag. <?= starts PHP execution, and outputs the first command.

<?php
// here, PHP code

// the closing tag
?>Here, raw text, always displayed
<?php
// more PHP code

// No final closing tag
