fopen and str_replace

[Anon]

I have been playing with this code for a bit now and still confused on how this is to work.

I want to
open a file on my server
copy it / rename it
do a find and replace
and be able to view that file

I can get everything done but the last step

$fp = fopen("http://www.server.com/temp.html","r");
if ($fp)
{ print"The file exists!"; }
else
{ print"The file does not exist";
}

I was able to do the copy and rename commands really easy but when I tried to replace it just didn't do anything.

$fp = str_replace('oldstring', 'newstring', $fp);

Do I need to write that back out to the file or should it have already happened?

$fp is a pointer, you'll need to fread() the file in order to do what you want....

Thanks, I got that working to a point.

I have it opening the file, reading the file, doing the find and replace and then printing it to the screen.

Am I right when saying that fwrite should print it back into a file.

Yep, you're "write" 😉
