Getcwd()

Understanding the 'getcwd' Function

The 'getcwd' function is a built-in PHP function that returns the current working directory of the script. This function does not take any parameters and returns a string that represents the current directory.

Syntax:

getcwd( void ): string

This function has no parameters, and it returns a string value that represents the current working directory.

Example:

<?php
echo getcwd();
?>

Output:

/home/user/public_html

How to Use the 'getcwd' Function

Using the 'getcwd' function is simple. All you need to do is call the function, and it will return the current working directory of the script. You can then use this value to perform various file operations within that directory.

Example:

<?php
$current_dir = getcwd();
$file_path = $current_dir . '/test.txt';

$file_handle = fopen($file_path, 'w');
fwrite($file_handle, 'This is a test file.');
fclose($file_handle);
?>

In the above example, we get the current working directory using the 'getcwd' function and store it in a variable called '$current_dir.' We then append the filename 'test.txt' to the end of the directory path and create a new file in that directory using the 'fopen' function. We then write some data to the file using the 'fwrite' function and close the file using the 'fclose' function.
