PHP preg_replace: how to replace spaces inside html tag

Question

I need to replace spaces inside a tag to other symbol. For example:

<p class="hero big" style="color: inherit; border: none">Super big hero <br />example Yeah</p>

to

<p~class="hero~big"~style="color:~inherit;~border:~none">Super big hero <br~/>example Yeah</p>

I'm new to regexp and don't know to start with. I'm able to replace spaces everywhere, but not inside a tag.

Ho to do it? Could you please provide working php code?

try this, It will replace spaces inside tag with ~

<?php
  $data = '<p class="hero big" style="color: inherit; border: none">Super big hero <br />example Yeah</p>';
  $replace = preg_replace('/(<[^>]*)\s+([^<]*>)/', '$1~$2', $data);
  echo $replace;
?>

It changes only the last space inside tag. Could you fix it? And replace $before with $data. – Somerussian May 23 '16 at 10:23

Try this

$text = htmlspecialchars('<p class="hero big" style="color: inherit; border: none">Text <br />Text</p>', ENT_QUOTES);

$text = preg_replace('/\s+/', '~', $text);

echo $text;

Note:- Treat html tags and main text separately

Doesn't work - it changes spaces everywhere. Could you fix it? – Somerussian May 23 '16 at 10:23
told you, you have to add the text like, 'Super big hero' after the conversion. Add it later – vishal May 23 '16 at 10:25
how to do it? Function will get some text and should perform some actions with it. It won't combine something by itself. – Somerussian May 23 '16 at 10:30

Thanks to PHP preg_replace: how to replace text between tags?, here's a solution:

<?php
$s = '<p class="hero big" style="color: inherit; border: none">Super big hero <br />example Yeah</p>';
$text = preg_replace_callback('#(<)([^>]+)(>)#', function($matches){
    return $matches[1].str_replace(" ", "~", $matches[2]).$matches[3];
}, $s);
?>

Do you see these double quotes which will make your code snippet fail? – Jan May 23 '16 at 16:27

You can use (*SKIP)(*F) to skip outside tags like this:

$str = preg_replace('~>[^<]*(*SKIP)(*F)|\s+~','~', $str);

See demo at eval.in
