Timestamp. Basically, you want to use timestamp if you will use the datetime value in other country, or places with other timezone. For example, you are in USA and you save the timestamp December 1, 2010 12:20:00 in your database. When you go to China for example, and you recover …

I don't think PHP supports templates, considering the fact that it is a dynamic language.

If you are working with a large project, it is much advisable to use the magic method __autoload() to include class files, rather than including them manually. Including class files manually is frustrating especially if working with large set of classes, so i advice you to learn using __autoload().

I've just learned how to use vectors. I'm thinking about, what is the best way to create a vector, IF you do not know its initial size. Here are some of my options. 1.) This is the simplest I think, but is there any memory issue about this technique? [CODE] …

So, I'm really frustrated with this problem. I desperately need some good explanation about this. Why does the calling function does not reflect the change done in the called function? despite the fact that I pass the variable via pointer. Any explanations please. Thanks in advance.

Function 2: the 5th line should be: s[i] = toupper(s[i]); toupper() fucntion is returning a value, it is not directly manipulating the string, so you still need to assign the current character to the returned value. Hope it helps.
