Newbie Traps & Pitfalls
PHP will let you get away with a lot of syntax mistakes which are perfectly valid code but not what you intended. Most of the following produced no immediate error messages; the code simply wouldn't work, and it took me several edit-upload-run cycles to find each problem. Here are some mistakes I made when re-learning PHP in 2005 after not using it since 1997:
- Classes
- Member vars and functions must always be referred to using $this->fname()
- However, var members do not take a $ prefix: $this->varName
- Operators
- The "is equal to" comparison operator is "==" (as in c/c++), not "="
