preg_replace: upper and lower-case

northk

i have done a search-string highlighting in a search result. i use the i-modifer with preg_replace() to match all strings, neglecting the case in which they are typed in.

but i don't want to change the case in the search-result print-out.
seems that doesn't work with preg_replace() ?!

example:

$replace_what = "/myquery/i";
$replace_with = "<font color="red">myquery</font>";
$query_result = "MyQuery is here";
preg_replace($replace_what, $replace_with, $query_result);

produces (of course):

myquery is here

can i add a regexp to the $replace_with or $query_result, so that it prints out:

MyQuery is here

or have you got a hint for a good workaround here?

thanks..

Why not try this? lol... I will look into it more later.

$replace_with = "<font color="red">MyQuery</font>";

this would work, if it would be a static search 😃

Hi northk,

I think a backreference is what you need.

preg_replace('/$keyword/i', '<font color="red">$0</font>', $query_result);

northk

thank you so much, xblue!

it worked..

and i'm happy now 🙂
