str_replace or ... ?

[ibzi]

Let's say I have a paragraph of text.


"This forum is phpfreaks.com and the person posting this message goes by the Username of ibzi. This is just a paragraph to show an example to the fellow helpers."

Now lets say I want to replace all the occurence of the word "and" regardless about the case. It can be And or AND or aND etc.

How would i do this? I want to replace it with something like:

and >>>>>> <a target="_blank" href="search.php?q=and">and</a>

I tried preg_match but I dont know how to use the function, i constantly get wrong result near the "_blank".

Please help.. it will be appreciated.

You definately want regular expressions. Try preg_replace though. There are plenty of regular expression generators to help you get it just right.

You could do it with a regex or you could do it with a simple str_replace()

$data = str_replace(array("and", "AND"), "<a href......>", $text);

if however the and might be mixed case you would want to look at regexes, which sadly I am rubbish at :)
