There's a number of functions in PHP that will give me the position of

overlooking a function that already has the functionality that I'm
searching for?  Or does anyone have any ideas how I can accomplish this
efficiently since my search strings can be quite long?


try this

preg_replace('/(weather)/i', "<strong>$1</strong>", 'This is the worst
weather ever.  Weather around
here is terrible. ')

Thanks Matt. I think that will do the trick. Let me see if I understand it correctly. the "i" will make the search case-INsensitive, and the parenthesis around "weather" will store what it finds in the variable $1? Is that right?


Also consider str_replace() as it's faster albeit case
sensitive.  str_ireplace() exists in PHP 5.  Just another
option, I'm surprised you didn't find it when looking
around strpos() and friends.

Your assumptions above are correct, sorry Matt for stepping
in! :)  I prefer cold weather.

Thanks Philip. I did notice str_replace() but it didn't look like I could use it without it actually replacing what it found instead of just adding strings before and after it. Am I wrong?
