Advantages of PHP:

1. Easy to Learn: PHP is a server-side scripting language that is easy to learn compared to other web development languages such as ASP.NET or Java.

2. Open Source: PHP is open-source, which means it is free to download and use. It is developed and maintained by a large group of PHP developers, this will helps in creating a support community, abundant extension library.

3. Cross-Platform: PHP is cross-platform, which means you can deploy your application on a number of different operating systems such as windows, Linux, Mac OS etc.

4. Compatibility: PHP is compatible with almost all local servers used today like Apache, IIS etc.

5. Embedding: PHP code can be easily embedded within HTML tags and script.

Disadvantages of PHP:

1. Security: Since it is open sourced, all people can see the source code. If there are bugs in the source code, it can be used by people to explore the weakness of PHP.

2. Not Suitable for Large Applications: Hard to maintain since it is not very modular.

3. Weak Type: Implicit conversion may surprise unwary programmers and lead to unexpected bugs. For example, the strings "1000" and "1e3" compare equal because they are implicitly cast to floating point numbers.

4. Speed: PHP can be slow relative to other programming languages.

5. Error Handling Facility: PHP lacks the error handling facility. If any issue arises, then the entire script will stop the execution.
