All the Google-like highlight functions above mess up when the needle is within the url too.
getHTMLHighlight function below works fine:
<?php
function getHighlight($needle, $haystack)
{
return preg_replace('|\b('.quotemeta($needle).')\b|iU', "<b
style=\"background-color:#FE923A\">".'\\1'."</b>",
$haystack);
}
function getHTMLHighlight($needle, $haystack)
{
$parts = explode(">", $haystack);
foreach($parts as $key=>$part)
{
if($pos = (strpos($part, "<")) === false)
$parts[$key] = getHighlight($needle, $part);
else
{
$partLeft = substr($part, 0, $pos-1);
$partRight = substr($part, $pos, strlen($part));
$parts[$key] = getHighlight($needle, $part) . $partRight;
}
}
return(implode(">", $parts));
}
?>
