search and replacing but keeping the letter case in tact

[laredotornado@zipmail.com]

Hello,

Using PHP 4, how would I do the following? I want to do a case
insensitive search on a string and replace it with "<span>" tags
opening and following the string in question. However, when I replace
the string, I want to preserve whatever the case was before. So, for
example, given

$search_str = "abc";
$main_str = "ABCDE"
$new_str = highlightSearch ($main_str);

I would like "$new_str" to contain "<span
class='highligh t'>ABC</span>DE".

Does that make sense? Any ideas?

Thanks, -

Use a regular expression :)

$haystack = preg_replace(
'/(abc)/i',
'<span>$1</span>',
$haystack
);

Just a variant method :

<?php
$search_str = "abc";
$main_str = "ABCDE";
$new_str = eregi_replace ("(abc)", "<span>\\1</span>", $main_str);

?>

Note: eregi_replace slower than preg_replace
