New Comment:
without fwrite() it is significantly faster, gives about 5-6 seconds.
But in Perl without print OUT $_; it gives around 1-2 seconds. So it is
still slower in PHP because of fgets().

Can you try your tests with the fwrite() line commented out?

I did an
`echo strlen($line).",";`
Here are the lengths for some of the first few lines:
42,7,18,11,71,13,8,7,42,7,20,11,73,70,68,63,13,8,7
It looks pretty much like this for the rest of the file. Lines between
1 and 100 chars in length.
Note: It isn't the start up cost for sure because I measured the time
just around the while loop with the same results.

How long are the lines in your file?

Startup costs could be 8 seconds or more depending on the extensions
you are loading. That said PHP's fgets() is still slower then Perl's
because of it's implementation that does not wrap the C library fgets()
or getline(), but rather uses custom code.

I don't agree that this is a bogus bug. You want to tell me that the
start up cost is responsible for 8 seconds? Than you have a performance
bug with your start up cost. Run it with fread($fin, 1024); where did
the start up cost go? Simplifying the script to while($line =
fgets($fin)){} doesn't help either. And automatic detection of new
lines is disabled. Did you run some of your own tests?
