PHP provides a convenient way of working with files via collection of built in functions, some of the functions are file open, file read, file close, file write, Appending a file and uploading a file.
(i.e.): fopen(), fread(), fclose(), fwrite(), file_put_contents(), etc.

File handling is needed for any web application development process. File handling in PHP similar as file handling is done by Clanguage. PHP has many functions to work with normal files.

Post Method	Get Method
The input data sent to the server with POST method is stored in the request body of the client's HTTP request.	The input data sent to the server with POST method via URL address is known as query string. All input data are visible by user after they click the submit button.

The GET and POST methods are used for sending the data to the server and the main difference between them is that GET methods append the data to the URI defined in form's action attribute POST methods attaches data to the requested body.

(i) To get form data, we need to use PHP $_GET and S_POST.
(ii) To retrieve data from get request, we need to use $_GET and for post request $_POST.
(iii) We can send limited amount of data through get request and large amount of data through post request.
