CKeditor remove extra whitespace

问题

I'm using CKeditor for a text editor and it won't remove extra whitespace.

I've tried

$foo = strip_tags($foo);
$foo = preg_replace('/\s+/',' ',$foo);

I don't know of any other way to remove whitespace from here. Any ideas?

Thanks

回答1:

try these:

$foo = preg_replace('/\s{2,}/', ' ', $foo);

or

$foo = preg_replace('/( )+/', ' ', $foo);

or this one removes line breaks too

$foo = trim(preg_replace('/[\s\t\n\r\s]+/', ' ', $foo))

Update

Try this one:

$foo = trim(preg_replace('/( )+|\s\K\s+/','',$foo));

Solved If anybody is curious, I solved this by cleaning them before they went into the database.

  $cpbody = trim($_POST['cbody']);

  $cpbody = preg_replace("/\<p\>\&nbsp\;\<\/p\>/", "", $cpbody);
  $cpbody = preg_replace("/\&nbsp\;+/", " ", $cpbody);
  $cpbody = preg_replace("/\s+/", " ", $cpbody);

  $cpbody = htmlentities($cpbody);
