I'm trying to get this darn eregi_replace() to work, but it doesn't produce any results at all. I want it to find all occurances of PHP variables. Here is the regexp $output = eregi_replace("^[\$]{1,2}[a-zA-Z][0-9]+$", "<b>\\1</b>", $var); As you might guess this is for a syntax highlighting function I am trying to write. Anyone have any ideas why it's not working? Please copy me directly, as I'm on the digest. Thanks!

I prefer the PCRE regex syntax, this should do it: $output = preg_replace('!^\${1,2}\w+$!', "<b>$1</b>", $var); because "\w" is the same as "[A-Za-z0-9_]" (though perhaps it is in POSIX regexes too). Erik ---- Erik Price Web Developer Temp Media Lab, H.H. Brown pricee@hhbrown.com
