Remove img class using preg_replace

I want to remove the following line in php 

<img class="hSprite" src="something" width="160" height="120"
sprite="/t/3010187.jpg" id="3010187">

I tried the following but its not working 

preg_replace("@<img class=\"hSprite\".*?>@s", "", $html);

EDIT I want to delete the whole line so there should be nothing output

yuo can use this simple regex:

/<img.*?class="hSprite".*?>/

i.e.:

<?php

$html = <<< LOL
 <div class="refsect1 description" id="refsect1-reserved.variables.server-description">
  <h3 class="title">Description</h3>
  <p class="para">
   <var class="varname"><var class="varname">test</var></var> is an array containing information
   such as headers, paths, and script locations. The entries in this
   array are created by the web server. There is no guarantee that
   every web server will provide any of these; servers may omit some,
   or provide others not listed here. That said, a large number of
   these variables are accounted for in the <a href="http://www.faqs.org/rfcs/rfc3875" class="link external">test 9999</a>, so you should
   be able to expect those.
  </p>
<img class="hSprite" src="something" width="160" height="120"
sprite="/t/3010187.jpg" id="3010187">
LOL;

$newHtml = preg_replace('/<img.*?class="hSprite".*?>/sim', '', $html);

echo  $newHtml;

Why not you tried dom class in php here using dom and xpath query it is able to remove the class from that img node. Don't depend on regex for dom related things use Dom classes provided by php team. 

$text = 
<<<heredoc
        <img class="hSprite" src="something" width="160" height="120"
sprite="/t/3010187.jpg" id="3010187">
heredoc;

$doc = new DOMDocument();
$doc->loadHTML($text);

//$img = $doc->getElementsByTagName("img")->item(0);

$xpath = new DOMXPath($doc);

$expression = "//*[contains(@class, 'hSprite')]";
$classElements = $xpath->query($expression);

foreach ($classElements as $element) {
    //$element->attributes->getNamedItem("class")->nodeValue = '';
    $element->parentNode->removeChild($element);
}

//echo $doc->saveHTML($img);
echo $doc->saveHTML();

Use preg_replace() to remove img tag from string

<?php

$html='nothing<img class="hSprite" src="something" width="160" height="120"
sprite="/t/3010187.jpg" id="3010187">';

$content = preg_replace("/<img[^>]+\>/i", "", $html); 
echo $content;

<?php
echo str_replace("hSprite","",$html);
?>

You can use php function for replace this class.

You need to only select the class. This should do it for you:

preg_replace('/(?<=\<img)( ?class="[\w]+")/', '', $html);
