How to read data from a file stored in XAMPP webserver using PHP ?

  • Last Updated : 01 Dec, 2020

We have given a file stored on XAMPP server and the task is to read the file from server and display the file content on the screen using PHP. We use some PHP functions to solve this problem.

File: A file is set of data stored in a disk in different formats. For example – .txt, .exe, .pdf etc 

fopen() function:  The fopen() function in PHP is an inbuilt function which is used to open a file or a URL. It is used to bind a resource to a steam using a specific filename. The filename and mode to be checked are sent as parameters to the fopen() function and it returns a file pointer resource if a match is found and a False on failure. The error output can be hidden by adding an ‘@’ in front of the function name.

Syntax:

fopen('filename', filemode)

Here, file name is name of the file and file mode includes read(r) mode,
write(w) and binary(b) mode etc.



  • fopen($geek, r) — Here we are opening geek file in read mode.
  • fopen($geek, r+) — Here we are opening geek file in read and write mode.
  • fopen($geek, w) — Here we are opening geek file in write mode.
  • fopen($geek, w+) — Here we are opening geek file in read and write mode.
  • fopen($geek, b) — Here we are opening geek file in read and write mode.
