Your kernel strips the first line, and so PHP sees the last 3 lines. As
it doesn't know that the kernel stripped the first shebang line it's
obvious that your line 3 reports line 2.

Excuse me, but I don't understand why this isn't a bug. The only
reference to __LINE__ I can find in the documentation is here:

http://www.php.net/manual/en/language.constants.php

I can find nothing that suggests it is reasonable that __LINE__ counts
are off by one when used in #! prefixed command line scripts, (but not
in other uses) and I can see no reason why this would be considered
reasonable behaviour.

Can someone give me at least a 1 sentence explanation instead of just
hitting the 'quick-fix' RTFM button?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The built-in variable __LINE__ undercounts by 1 on command-line scripts
that begin with a #!path-to-php line. For example:

#!/usr/local/bin/php -q
<?php
echo "Line 3 reports ".__LINE__."\n";
?>

This script will output:

Line 3 reports 2

This issue also applies to (at least) some other 4.1+ releases.
