Same goes for e.g. the C lint -=20 int main() { char *p; p=3D0; *p=3D0; } this is 100% syntactically correct, but will core dump if you run it.=20= --=20 Per Jessen, Z=C3=BCrich (24.2=C2=B0C)

Same goes for e.g. the C lint - Sorry, but that's not what I remember from my C days, nor what wikipedia says "lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs (likely to be bugs) in C language source code." In fact, what would be the point of a C lint that does that? It's already done by the parsing/syntactical analysis part of the compiler, there'd be no point writing a separate program (lint) to do that. Anyway, yeah, I accept that that (syntax checking only) is what php -l does, even if I think it's wrong, or at least incorrectly described :) > -- > Per Jessen, Zürich (24.2°C) It feels warmer than that today. Maybe it's because my code isn't working X(

Documentation bug, or is my > brain failing to work today? Sounds like a roundabout way of saying "You can only find run-time errors (such as undefined functions) by actually running the script".
