PHP Bug Type: Feature/Change Request
Bug description: wish: syntax error, unexpected $end should show start point
Description:
------------
If I have a script with a syntax error, such as a missing '}' somewhere,
PHP will helpfully tell me that there's a problem, but direct me to look in
the wrong place.
The error message is as follows:
Parse error: syntax error, unexpected $end in [FILENAME] at
[NUMBER_OF_LAST_LINE]
This is unhelpful for 2 reasons.
* It isn't clear what type of syntax error would cause this - there's no
way to know what character PHP was expecting to see.
* I have no easy way of finding the offending line where the bug really
lies, apart from commenting out parts of the source and doing a
binary-search within it. Essentially, PHP is saying "You have an error, but
I won't tell you where".
Expected result:
----------------
The following would be clearer and *far* more helpful.
Syntax error: unexpected $end in [FILENAME] at LINENUM: missing
an expected '}' character. (The corresponding, unmatched '{' is
probably at line xxx.)
Of course, it's not always possible for PHP to know which open-brace is
the unmatched one - however, it could usually take a reasonable best guess
by iterating *backwards* through the source, and doing:
1 $nest_depth=0
2 If a '}' is encountered, $nest_depth++
3 If a '{' is encountered, $nest_depth--
4 If $nest_depth == -1, we have located the open-brace that isn't
closed. Print LINENUM.
