The file() function ...

I am using php4 RC1 + apache 1.3.12 and I am always getting segmentation fault when I try to use the file() function (what it does ? ... reads an entire file into an array). Anyone knows about that ? It works in newer releases of php ? (I wanted to use this function to find the number of lines in the file. I tried another solution then but it does not work every time bcs. the lines from the file are not always the same dimension: the size of file / the number of characters from one line = number of lines. Yes, I know that is not quite an elegant solution ... :) ) And another question a little off-topic (javascript): how can I open with "window.open" method an maximized window in IE5 ? And where can I find documentation about the IE javascript ? I have some from Microsoft but I can't find there any help about window, document... methods and properties. In Netscape's documentation you can find that very easy. Tnx, Mihai PS: I thank all who replied to me about the progress bar :)) The conclusion about the progress bar: it cannot be done as I wanted to (( ... but I think that a little animated gif will be enough .. :))
