PHP is a programming language, just like Perl, Python, JavaScript, Basic and many other interpreted language.
Note: the PHP interpreter can be integrated into the webserver, or run standalone.
A PHP script runs on the SERVER.
When you visit a webpage your browser will execute its corresponding client scripts such as JavaScript scripts after downloading the webpage to your computer.
A PHP script can make use of resources in the server which contains the webpage you are visiting. Javascript has no direct access to such information (databases on the server, connection with external servers and services, users currently logged on server, etc.).
In fact nowadays Javascript can connect to server-side scripts to aquire any information there, but it is still run on the client (the webpage visitor's browser), not in the server.
For example, if your web server is very busy and slow, your Javascript will run as fast as visitors computers can meanwhile your Javascript script does not require communication to such slow server.
PHP is server-side because the code runs on the server, not in the browser. So when you load a website that is running PHP your computer contacts the server, the server executes the code, returns the results, and the browser just displays it.
It is a dynamic scripting language which is open source. In other words it allows changes to be made without the need to unload it off the server and you don't have to pay anything to use it
Yes.
You can't. You need a Server-side scripting language such as php.
PHP uses a Perl-like syntax, but is simpler, less consistent and more limited.
Scripting languages, of which JavaScript is one, are light-weight programming languages (i.e. not a fully featured programming languages) that exist to enhance HTML and web pages so that they are dynamic or interactive. They interact with, amend or generate HTML. They would not have any function outside of a web page environment.
A bot can be written in a server-side language like php, asp, etc.

The difference between "scripting" and "programming" is largely one of semantics; they're essentially the same thing. A purist is more likely to call writing in a usually interpreted language (such as PHP) "scripting" and writing in a usually compiled language (such as C) "programming". But either way, you're writing a set of instructions for the computer to follow, and some "scripts" can be as (or more) complicated than many "programs."
When referring to the mail setting PHP, it is a server side scripting language that is designed for web development. PHP can also be used for a general purpose programming language.
In order to obtain a job in PHP programming one must have a multitude of skills. The most important skill is the knowledge of server side scripting language.

PHP itself is a scripting language, and uses it's own PHP interpreter (engine).
In web programming you have: - Server side scripting: using languages like PHP, Ruby, ASP or JAVA - Client side scripting: usually meaning JavaScript, although there are others
Pearl is not a programming language and it's definitely not related to PHP. It's a pricey object you give to your significant other. Perl on the other hand, is a scripted JIT programming language principally aimed at IO (file operations) whereas PHP is also a scripted JIT programming language but that is principally aimed at website server-side scripting.
