如何从PHP中的字符串中删除带有超链接的单词？

I need some help with removing words that contains hyperlinks in PHP. Example:

I was here dumb*

*has hyperlink

I want it to be like this:

I was here

without dumb

Can someone help me on this? Thanks.

Edit:

I am gonna load "This page" and then remove all words containing hyperlinks. Example: "LYSSNA, BILD SVENSKA / BILD FINSKA"

function findAndReplace($arr) {
    return '<strong>'.$arr[1].'</strong>';
}

$inputText = 'Why use <a href="#"  style="padding-left:5px"> PHP </a>?';
echo "<br />Input is: <br />";
echo $inputText;

$returnText = preg_replace_callback('@<a(?:.*)>(.*)</a>@isU', 'findAndReplace', $inputText);

echo "<br /><br />Output will be: <br />";
echo $returnText;

EDIT

Since you edited your original post: Try:

$new_string=preg_replace ("/<a.*>/i","",$string);

I think this should work:

$string_without_hyperlinks = preg_replace('/<a\s.*?>.*?<\/a>/s', '', $string);
