How to execute html code before php execution?

Question

PHP

There is a php file. Its appearance is approximately the following (I replaced the angle brackets with square brackets, because Habr does not like them.)

[html]<br/>
<br/>
[script type=&quot;text/javascript&quot;]<br/>
тут тело скрипта<br/>
[/script&gt;]<br/>
[/html]<br/>
<br/>
&lt;?php<br/>
sleep(5000);<br/>
php-код<br/>
?&gt;

When this file is executed in the browser, the php code is executed after 5 seconds, the html code does not work at all (viewing the page source code through the browser shows emptiness). If you remove all the php code, the html code works fine and can be seen through viewing the html page.
There was an attempt to solve the problem in this way:

&lt;?php<br/>
echo='[html]<br/>
[script type=&quot;text/javascript&quot;]<br/>
тут тело скрипта<br/>
[/script]<br/>
[/html]';<br/>
sleep(5000);<br/>
php-код<br/>
?&gt;

But it didn't change anything at all.
What is the problem? Where to dig?

Answer 1

The final solution might look something like this:

[script>
$(document).ready(function()
{
$("#redirect").load('index.php');
});
[/script>
[html>
[div id='redirect',name='redirect'>
[/div>
[/html>

Answer 2

There is no problem here . There is a misunderstanding of how different entities work - server and client.
php is executed not in the browser, but on the server and sends the sourcing to the browser through the web server, and then javascript (if enabled) comes into play in the browser.
in your case, the only way to execute js first is to load the page, and then use Ajax to make a request to the server to the php script.

Answer 3

From the generated html page using ajax, after the necessary pause (setTimeout), pull the desired php script and do what you need.
Sleep, etc. - crutches, which are better not to use.

Answer 4

Your main problem is that sleep(5000) is not 5 seconds, but 5000 seconds. Wait 5000 sec. and you will have html :-)

Answer 5

Read what an output buffer is and its management functions ( flush , ob_flush , etc.)

Answer 6

Run long running processes in a separate thread is better.
The view of a tab hanging in the “loading” status for an hour and a half (5000 seconds) is somehow completely unattractive.

Answer 7

Try creating (or adding to an existing) .htaccess file
With the line:
RemoveHandler .html .htm
AddType application/x-
httpd-
php .php .htm .html
