how to replace string, ignore the \n \r and tab etc.

blackhorse

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td>Hello </td>
    <td>World   </td>

  </tr>
</table>

How can replace "string" like above, ignore the new line, tab and empty space?

Thanks!

what are you trying to replace? with what? in what?

Since there are three characters after 'World', I'm guessing those are the ws chars.

// Remove any amount of all kinds of white space characters that appear just before a '<'
$html = preg_replace('#\s*<#', '<', $html);

// If it's just after world
$html = preg_replace('#(World)\s*<#', '\1<', $html);

Sorry, This is just an example, I was trying to do find and replace, ignore the white space and tab and new line etc.

For example, I want to be able to replace the whole table with '', no matter that table is

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td>Hello </td>
    <td>World   </td>

  </tr>
</table>

<table width="100%" border="0" cellspacing="0" cellpadding="0"><tr><td>Hello</td><td>World</td></tr></table>

Something like "find and replace" ignore white space in dreamweaver. Thanks!

If one single SP is acceptable, this will do the trick

$html = preg_replace('#\s*#', ' ', $html);

Else I suppose you'd have to use DOM in combination with trim
