PHP_SELF - silly question

Im a little brain fried today and I have a silly question. I have a script (imagine that huh?) that I want to pull some code out of and put in a function that is contained in a seperate file. The function however inlcudes some lines with $PHP_SELF in a link (a href). When I remove the code from the running script and include it in a function file seperate from the script the function works fine as far as generating links etc, but when the link that includes $PHP_SELF is selected, the file of the running script is not passed. So in other words, when I have my function code in my running script, it generates some links that limit a query on a mysql database and pass data to PHP_SELF, the passed URL looks like this (for example): http://69.02.217.123/php4/php.exe/searchitem.php?sql=SELECT+%2A+FROM+items+WHERE+LCASE%28partnumber%29+LIKE+%27x%25%27+ORDER+BY+partnumber+&offset=100&numpage=3 But, when I move the code to create the links externally into a function, the link I end up with is like this: http://69.02.217.123/?sql=SELECT+%2A+FROM+items+WHERE+LCASE%28partnumber%29+LIKE+%27x%25%27+ORDER+BY+partnumber+&offset=100&numpage=3 Can someone shed some light on the best way to handle this? -- Larry H.
