A web service is a theoretical asset that gives an arrangement of capacities and is actualized by an operator, which sends and gets messages.

3. APIs

API extends for "Application Programming Interface".It is a set or decides that enables one bit of programming application to converse with another. Those "rules" includes CRUD operations. Application Programming Interface is a need since this is the lightest method to make, read, refresh or erase data between various applications over the web or HTTP convention. This data is displayed to the client in a moment particularly on the off chance that you utilize JavaScript to render the information on a site page.

4. SPL (Standard PHP Library)

SPL gives an arrangement of standard information structure, an arrangement of iterators to cross over items, an arrangement of interfaces, an arrangement of standard Exceptions, various classes to work with records and it gives an arrangement of capacities like spl_autoload_register()

5. Sessions

Sessions are a straightforward method to store information for singular clients against a one of a kind session ID. This can be utilized to continue state data between page demands. Session IDs are typically sent to the program by means of session treats and the ID is utilized to recover existing session information.

6. Exception handling

Exceptions can be handled by using some keywords in PHP. Keywords for handling all the exceptions. We can use multiple catches for a try block but cannot use multiple tries with a single catch statement. When an exception occurs it creates an object of exception type and throws it to catch statement. Catch statement catch that object and handle it and helps to continue the normal execution of the program. One more keyword is used to handle the exceptions and i.e. throw.

7. Regular Expressions

8. Bugs Debugging

There are different ways by which we can display error messages and debug the bugs of the program. To display an error message in the browser, set the property named display_errors configuration directive to On. To send errors to the web server, set the property log_errors to On.  If you want to display the error messages in both places then you can set them both to On.
PHP provides some constants to set the value of error_reporting such that errors of certain types get reported: E_PARSE (parse errors), E_ERROR (fatal errors), E_ALL (for all errors except strict notices), E_WARNING (warnings), E_NOTICE (notices), and E_STRICT (strict notices).

9. PHP & AJAX
