Bug #20035 __LINE__ miscounts with #!/path/php scripts
Submitted: 2002-10-22 19:34 UTC Modified: 2002-11-05 16:07 UTC
From: befletch at yahoo dot com Assigned: iliaa
Status: Closed Package: Scripting Engine problem
PHP Version: 4.2.3 OS: OpenBSD 3.1
Private report: No CVE-ID:
 [2002-10-22 19:34 UTC] befletch at yahoo dot com
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.

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

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?

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.

The shebang line doesn't get stripped off by the kernel, PHP does that. This is a bug.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
