Why HTML makes PHP function call to comment, when I echo from PHP function

Question

Im trying to echo whole modal with data from db. I want to use my other functions "getLocations and getdescriptions" in my new function. But... Html shows those functions as comments "<!--?php echo getLocations(); ?--> & <!--?php echo getdescriptions(); ?-->". How I can make these echos to work.

Code is not complete, so there is possible many problems, but this echo is my problem right now.

$output .= "
<tr data-toggle='modal' data-target='#startWorkTime".$location_row['name'].gmdate("j", $start_day)."' href=''>
    <td class='column7'>".gmdate("j", $start_day).".".gmdate("n", $start_day).".".gmdate("Y", $start_day)."</td>
    <td class='column7'>".$location_row['name']."</td>
    <td class='column7'><a href='https://www.w3schools.com/'>".$row['msg']."</a></td>
    <td class='column7'>".gmdate("G", $sum)."h ".gmdate("i", $sum)."m</td>
</tr>

        </div> 
    </div> 
</div>";

How I can prevent to html shows those functions as comments "<!--?php echo getLocations(); ?--> & <!--?php echo getdescriptions(); ?-->".

PHP doesn't run in the browser, you need to install the PHP interpreter and enable it in your web server. — Álvaro González, Nov 06 '22 at 18:50
Also you need to provide, environment details or any other solutions you tried. — HKTE, Nov 07 '22 at 01:14

Change code like this:


$oupput .= "
<tr data-toggle='modal' data-target='#startWorkTime".$location_row['name'].gmdate("j", $start_day)."' href=''>
    <td class='column7'>".gmdate("j", $start_day).".".gmdate("n", $start_day).".".gmdate("Y", $start_day)."</td>
    <td class='column7'>".$location_row['name']."</td>
    <td class='column7'><a href='https://www.w3schools.com/'>".$row['msg']."</a></td>
    <td class='column7'>".gmdate("G", $sum)."h ".gmdate("i", $sum)."m</td>
</tr>

Those tags are HTML encoded because you have them inside a double-quoted string. PHP is interpreting the tags as actual PHP open/close tags, and since they're in a string, they just output as-is. To fix this, you can use heredoc syntax instead:

$output .= <<<HTML
...
<?php echo getLocations(); ?>
...
HTML;

This will allow actual PHP code to be interpreted within the string.

It seems you have a deeper issue causing the PHP to not be parsed at all. I would double-check your PHP file extension and server configuration to ensure PHP is being parsed correctly.

Why HTML makes PHP function call to comment, when I echo from PHP function
