highlight word in div

[jijodasgupta]

i hav a search engine runnin...

is there a way in php to highlight the searched word in a div using php...?????

Yes.

 

str_replace or preg_replace will help to get you started.

 

$string = "highlight the word the in this string";
$string = str_replace("the", "<span class=\"highlight\">the</span>", $string);

[jijodasgupta]

that is wat i had done

<?php
if(isset($_POST['searchterm']))

{	
$searchitem=$_POST['searchterm'];
//where searchitem contains the word which is searched..
return (ereg_replace($searchitem, "<span class='highlight'>$searchItem</span>", $buffer));




?>

 

 

still not workin....

I would suggest against using ereg_replace as it is being depreciated.

 

As far as why it is not working, notice in the replace segment you use "$searchItem"  php is case sensitive. It should be all lower case.

for case insensitive

$string = preg_replace('#('.$search.')#si','<span class="highlight">$1</span>',$string);
