PHP output in HTML files?

Question

PHP

Good day! Please tell me where to find information on php where it is described what the php tags do so to speak. And it is "<?php ?>", "<? ?>", "<?= ?>" that interests. I remember reading it somewhere, but I can't remember where :(

Answer 1

<?php ?> - opening and closing php code tag, if there is only php code in the file (for example, some class), the closing tag is not needed. The tag is correct, according to the standard, it is better to use it.
<? ?> - short tags, a shortened version of the one above. Can be disabled in the config, better not to use.
<?= ?> - they are the same, <?=$var?> analogue of <?php echo $var; ?>

Answer 2

In .htaccess add something like this
AddType application/x-httpd-php .html .htm

Answer 3

php.net/manual/en/language.basic-syntax.php

Answer 4

The tags tell the interpreter where the actual php code is located. The rest of the code is skipped.
That is, the interpreter goes through the code, finds one of the opening tags and processes it until it meets the closing tag, then repeats.
Explanations SharuPoNemnogu will not repeat =)
