删除代码空白（WordPress）

Question

Basically I have a WordPress loop and I need all the code to be compressed and all unnecessary white-space to be stripped like so:

<article><p>Content</p></article><article><p>Content</p></article><article><p>Content</p></article>

I am including the loop file using:

<?php get_template_part('library/inc/loop'); ?>

Just wondering if there is a simple way like:

<?php trim( get_template_part('library/inc/loop') ); ?>

If this is possible all my problems would be solved, any help is much appreciated. Cheers!

Answer 1

To remove all leading and trailing whitespaces within HTML elements, you might use

// Remove whitespace before '<'
$html = preg_replace('~\s+<~', '<', $html);
// Remove whitespace after '>'
$html = preg_replace('~>\s+~', '>', $html);

This will leave any whitespace within text intact.

Answer 2

I'm not too familiar with the "back end" of WordPress, however you could try

str_replace(" ","",$data);//Find whitespace " " and replace with ""

To clarify: whitespace when outputting, or whitespace in the source code?

Or as you put try using trim(). I hope this helps you.
