Based on the above, I don’t find any difference between PHP and Java! There are a lot of things to learn about PHP, Java, and .net! Impetuous people tend to say: If you are not good at PHP, you should learn Java, C#, VB.NET: --Is it because you are not good at it!? Impetuous people tend to ask: Which one is better, PHP or Java, C#, or VB.NET? - Let me tell you, both are good - as long as you learn it well; Impetuous people tend to ask: What should I learn? - Don’t ask, just learn; Impetuous people tend to ask: Is there any way to make money with PHP? - Hey, then go rob a bank, there is more money to be made!
