Courtesy of PHP.net:

<?php
function strip_only($str, $tags) {
    if(!is_array($tags)) {
        $tags = (strpos($str, '>') !== false ? explode('>', str_replace('<', '', $tags)) : array($tags));
        if(end($tags) == '') array_pop($tags);
    }
    foreach($tags as $tag) $str = preg_replace('#</?'.$tag.'[^>]*>#is', '', $str);
    return $str;
}

$str = '<p style="text-align:center">Paragraph</p><strong>Bold</strong><br/><span style="color:red">Red</span><h1>Header</h1>';

echo strip_only($str, array('p', 'h1'));
echo strip_only($str, '<p><h1>');
?>

http://us.php.net/manual/en/function.strip-tags.php

 

Both return:

Paragraph<strong>Bold</strong><br/><span style="color:red">Red</span>Header

 

So, in your case, call the function as:

echo strip_only($str,array('a','span')); //echoing so you can see the output

Hope that helps!

This is a slightly improved version of that function which can strip all the tags at once without a foreach loop. I also removed the section to handle <> in the value when passed as a string. I figured if the values can't include those when passing the values as an array then the same rules should apply when passing as a string. Instead, I modified it to allow multiple values to be passed in a single comma separated string:

 

<?php

function strip_only($str, $tags)
{
    if(!is_array($tags)) { $tags = explode(',',$tags); }
    $tagsPattern = implode('|', $tags);
    return preg_replace("#</?({$tagsPattern})[^>]*>#is", '', $str);
}

$str = ' <br><br><span id="1.612802118875386"><b>Other Page: </b>Matte Card<br><b>Gramage: </b>80 gram<br>sdafsdaf<br> <a href="#" onclick="removetext(1.612802118875386)"> Remove </a> </span><br><br><span id="1.014127052347593"><b>Other Page: </b>Matte Card<br><b>Gramage: </b>100 gram<br>sdfasfsdfdsfsdafsdafas<br> <a href="#" onclick="removetext(1.014127052347593)"> Remove </a> </span>';

echo strip_only($str, 'span,a');
// OR
echo strip_only($str, array('span', 'a'));

?>
