fopen() funciton in PHP | fileopen

 fileopen in PHP

In this article, we will discuss how to fileopen in PHP using the fopen() function. This function is used to open a file. It requires two arguments: first the file name and then the mode in which the file is to be opened.

Syntax:

fopen(string $filename, string $mode);

where,

file name represents the file to be opened and $mode represents the file mode like read-only, read-write, write-only, etc.

Example:

<?php
$handle = fopen("d:\\php\\file.txt", "r");
?>

PHP opening modes:

  • R  –  Opens the file in read-only mode.
  • r+  –  Opens the file in read-write mode.
  • W  –  Opens the file in write-only mode.
  • w+  –  Opens file in read-write mode.
  • A  –  Opens the file in write-only mode.
  • a+  –  Opens the file in read-write mode.

If an attempt to open a file fails then fopen returns a value of false otherwise it returns a file pointer which is used for further reading or writing to that file.
