减少PHP服务器请求

Question

Probably a very stupid question, but I'm wondering how php works. I'm trying to find ways to improve the php of my WordPress themes.

<?php
echo "PHP script.";
?>
<?php
echo "More PHP script!";
?>

Will I reduce the number of requests/processes if I put them together like this

<?php
echo "PHP script. More PHP script!";
?>

What I actually want to know is will there be a request to the server every time there is a < ?php and can I or do I reduce the number of requests by combining them?

I'm not sure you understand what a "request" is in this context, and you may be mixing terminology (which is leading to your confusion on the matter).

To answer the question... No, having multiple lines of PHP code in a single file does not perform additional HTTP requests.

When you make a request to a URL, such as:

http://www.example.com/somePage.php

That creates one request. The server-side code in somePage.php is processed in its entirety and the result of that processing is sent to the client in response to the request. At this point the request/response is done.

The request has literally nothing to do with how many lines of PHP code are on the page.

Well, in order to do that you first would need to identify something that needs to be improved. Don't just randomly shuffle your code around and hope it makes things better in some immeasurable way. Measure something, then improve that something.

If your page is loading slowly, find out where/how/why that's happening. Maybe you have some code that's taking a long time to process, maybe you have inefficient SQL queries, maybe you're transferring large images to the browser and the network is slow, maybe something else. Don't guess , measure .
