In this chapter, we have covered a great deal of material. You have learned how to work with magic quotes in PHP regardless of whether they are enabled, you learned how to encode and translate variables, and you have seen how to create a very powerful form validation script! If you have a good understanding of everything discussed in this chapter, you are well on your way to developing professional PHP code. If you are still having problems (especially with the form validation script), I suggest you go over the section again. If a particular function is bothering you, the PHP manual, as always, is an excellent reference and should be used without hesitation.
