Error reporting and handling:

PHP has many pre-defined functions and reporting constants that generate errors at runtime.

Community support:

PHP has a large community of developers who regularly updates documentation, tutorials, online help, and FAQs. Learning PHP from the communities is one of the significant benefits.
