Combined with the above, I don't see any difference between PHP and Java! PHP has as much to learn as Java or.net!
Impetuous people easy to say: PHP language is not, should learn Java, C#, VB.NET: - is your own line! ?
Impetuous people easy to ask: PHP and Java, C#, VB.NET which is good; - all right, I tell you - as long as you learn well;
Impetuous people easy to ask: I exactly should learn what: - don't ask, learn right;
Impetuous people easy to ask: PHP money: - suggest you go to rob a bank
