If you look at a PHP source file you will notice one thing. It's a source file. Not particularly surprising, but think about when you deploy a PHP application, what do you deploy? PHP source files. Now for many other languages; Java, C, etc when you deploy an application you deploy the compiled file. So, the question that you want to ask yourself is this, how much time does a PHP application spend compiling source files vs running the code? I'll answer that for you, a lot.

The world started to take notice of hacking as a serious crime or felony when Jonathan James, an American hacker, was first arrested for making intrusions into the Department of Defense computers between August and October 1999. Hacking happens mainly because of poor IT management, lack of control, lack of proper knowledge and exposure, haphazard computer networks, illogical system design, misconfigured systems and applications, etc. The number of readymade hacking applications, tools, code, etc, and their availability in the market are the real enticers to the "would be" hackers.

IFR rules restrict landing to a minimum 400 ft above ground level even when the same pilot can fly the plane through zero visibility from take off through descent.
