This rewind command seems quite godd to use, just that i cant understand how? Can I use it to go back to the beginnning of a file and then enter the information that I want to be placed there? Or how?

i cannot figure out how to use rewind either. if i put $fp=rewind($fp); it wont work and if i put rewind($fp); it just ignores it. helpie! thanks.

Ok. Rewind brings me to the beginning of a file. What brings me to the end? Because i need to just keep on adding info to a text istead of overwriting it again! Shouldn't there be some kind of EoF thing? Thanks!

This is what I did to open a file and add to the end, it was the only way that would work for me.. <PRE> $fp0 = fopen("file_to_open.txt", "r"); fclose($fp0); //Close the file fp0 $fp1 = fopen("same_file_as_above.txt", "w"); fwrite($fp1, "Text To Add"); fclose($fp1); //Close the file fp1 </PRE> Hope I helped a little bit.

Oops. Missed a line.. This goes between <PRE>$fp0 = fopen($fnews, "r");</PRE> and <PRE>fclose($fp0);</PRE>... Add this: <PRE>$contents = fread($fp0, filesize(file_to_open.txt));</PRE>

To add text to the end of a file use fopen("$path/$filename", "x")
