I just want to know the benefits of PHP

I know the benefits

You can do pretty much everything with PHP.
So can you with C++, and Pascal.

The advantage of PHP is the advantage of loosely typed languages, and scripting languages reunited.
Quick learning curve, quick to develop mockups, quick to deploy.

The drawbacks are those of loosely typed languages, and scripting languages reunited.
No safe guard against bad coding, less optimized, no enforced logic/storage/display separation out of the box (only via frameworks), implicit type casting.

Pick your poison.
