That's not that easy, you might also miss a "+" or something completely different.

i suggest you rethink
this is a feature request.

if all lines end with ; except for one.. and php is about to give a syntax error for the next line, you can be damn sure that a ; is missing.

The parser isn't line-oriented though.  

This is perfectly valid, for example:

$a =
$b =
$c = 0;

but this isn't:

$a = 1
$b = 
$c = 0;

Here we get "syntax error, unexpected T_VARIABLE" when it hits the $b there which is perfectly correct.  Throwing an error that assumes something that isn't there, a ';' at the end of the first line in this example, doesn't make any sense.  All we can do is throw an error when we hit something that doesn't fit in the grammar.  That is how all parsers work.  They match text to a grammar and throw an error when it doesn't match.  Trying to make the error handler guess how the code could be modified to make it valid is much too hard and error-prone.
