28. Get Temporary File Directory

Write a PHP script to get the directory path used for temporary files.

Sample Solution:

PHP Code:

<?php
// Generate a temporary file with a unique filename
// The tempnam() function creates a temporary file with a unique name in the system's temporary directory
$temp_file = tempnam(sys_get_temp_dir(), 'Tux');
// Output the path of the created temporary file
echo $temp_file."\n";
?>

Explanation:

Generate a Temporary File:

The tempnam() function is used to create a temporary file. It takes two arguments:

sys_get_temp_dir(): This function returns the path of the system's temporary directory.
'Tux': This string is used as a prefix for the unique filename.

Store Temporary File Path:

The path of the created temporary file is stored in the variable $temp_file.

Output Temporary File Path:

The echo statement outputs the path of the created temporary file, followed by a newline (\n).

Output:

/tmp/TuxN0kaAE
