using fwrite to append text to an existing file?

Hi

When you fopen your file for writing, use the "a" flag for appending, as in...

$fileId = ` fopen $filename "a"`;

Thank you Andrew for your response. The append flag will actually add the text at the end of existing content of the file. What if I want to add ti anywhere within the file? I should have been clearer though. What I want to do is:

say, I have a file dummy.txt which already contains some text. Now, I want to add a line, "this is the new line" after the 3rd line and again after the 7th line. Is it possible to do that? I hope I'm clear enough.

what i usually do is read all the lines into a "source" array, and then you can step through each line testing against a given value and write the lines to a "target" array, then all you have to do is write the "target" to the file, stomping over whatever is there.
