Haveing a little problem with 'str_replace'

pheagey

Ok, it's quite simple. I have my script open a file and remove a line of it using "str_replace". I've only gotten it to work when I enter only plain text to replace. I can not get it to replace the text using any variables or anything:
Here's what works:
str_replace("<?PHP include ('userFiles/original_Destroyer_test_qwe.php'); ?>", "", "".$filecontents."");
This deletes the line as needed.
Here's what I need to work:
str_replace("<?PHP include ('userFiles/$ModType".."$FileObjType".."$FileUsrName"._."$FileIs'); ?>", "", "".$filecontents."");
I've also tried putting it into a string and trying this:
str_replace("".$Listdash1."", "","".$filecontents."");
Any idea's why this is not working or a work around?
Thanks for your hep people!

Try this:

$string = "<!--$FileUsrName - $FileNoExt --><?PHP include ('userFiles/$ModType_$FileObjType_$FileUsrName_$FileIs'); ?><!---->";

str_replace($string, "", $filecontents);

no luck, same problem. Anyone else?

have you echoed the string when you're using the variables, to see what it actually does put out?

aaa crap. I just looked at it adn relized that is was echoing back the ZIP file istead of the PHP file. My bad. It works now. but thanks alot.
Well here it is. It takes a file that is passed to it and parses off part of it. Then open another file which contains links to the diffrent files and deletes the link from the link file, and resaves the link file.
