Bug #17101 Updated: Parse errors involving control structures should indicate the start of it

ID: 17101 Updated by: sander@php.net Reported By: destes@ix.netcom.com -Status: Open +Status: Closed Bug Type: Feature/Change Request Operating System: All PHP Version: 4.1.2 New Comment: There is no way how PHP can detect it. Consider the following (bogus) script: if($foo) { ... if($bar) { ... } How can PHP know which brace is missing? It can be if($foo) { ... } if($bar) { ... } but it can also be if($foo) { ... if($bar) { ... } } If you have a good idea how to detect it, please let us hear. Previous Comments: ------------------------------------------------------------------------ [2002-05-08 14:36:56] destes@ix.netcom.com A common scripting oversight is to forget to properly close control structures bounded by curly braces such as if: if ($var) { $foo = 1; $bar = 2; /* forgot the } */ ... When parsing this, PHP reports that the error occurred on the last line of the script - however many lines there are. For scripts that run many thousands of lines, and contain hundreds of control structures, this means a huge amount of time spent going over the entire code looking for the bad structure. It occurs to me that PHP should be able to determine where the START of the unended control structure is, and raise the parse error indicating that line (instead of the last line of the document). Adding this feature would greatly decrease debug times for people who occasionally make errors like these.
