HELP: Formatting using ereg_replace

[Anon]

I need a way to make a case sensitive replace of the word 'for', I want it to check if the for is either 'for', 'for(', or 'for{'. I think you can do this with eregreplace but i don't remember how.

Adding to this, if I have

'for(int' as my string, how can i make it so that it just formats the 'for' and not the (int?

ie, it should format to '<font color=\"#0000FF\">for</font>(int'.

Well, if there aren't any other 'for's running around...

read the file into a string...

ereg_replace ('for', 'FOR', $string)

write it to a new output.

actually, i figured it out,

<pre>
if (trim($current[$x]) == $words[$i])
{
$current[$x] = "<font color=\"#0000FF\">$current[$x]</font>";
} else {
$current[$x] = ereg_replace("(.)($words[$i])([()\;:<])(.)", "\1<font color=\"#0000FF\">\2</font>\3\4", $current[$x]);
//(.)($words[$i])([()\;:<])(.) OR ([()\;:<])($words[$i])
$current[$x] = ereg_replace("([()\;:<])($words[$i])", "\1<font color=\"#0000FF\">\2</font>", $current[$x]);
}

</pre>
