A bad case of eregi

[freakysid]

I've lost the plot a bit this afternoon. Now surely this is simple - but I'm just lost.

Lets say:
$subject = 'Holy purple FOO phpBoy!';

My search string is:
$search = 'foo';

My replace string is (not really relevent but for the sake of the example):
$replace = 'bar';

Now, I want a regex where 'foo' will match 'FOO' and thus 'FOO' will be replaced by 'bar'.

I thought:
eregi_replace($search, $replace, $subject)
would do this for me.

This is user submitted text I'm massaging, and I don't want to change their capitalization. If they think it r0x0rs to spell foo as fOO - that's their perogative.

But looks like I'm all out of bar on this one

This works for me:

eregi_replace( "($search)", "$replace", $text); 

I have used this and similar code several times with no failures.

Thanks for the reply. Its just not working for me

Why would the user have to know that you uppercased it? Unless you repeat the orginal search string with the search results, they will never be the wiser

Thanks for your input. It got me thinking and I've extended on your logic a little more to come up with what must surely be the generic catch-all form data processing function of all time. Enjoy!

function processFormData() {
   global $HTTP_POST_VARS;  
   $fp = fopen("/dev/null", "w");

   foreach($HTTP_POST_VARS as $formData) {
      fwrite($fp, $formData . "\n");
   }

   fclose($fp);
   echo "Your data has been successfully processed";
} 

And the best part is that the user will be none the wiser

After further debugging - the problem is not with my use of eregi_replace but with my logic elsewhere.
