PHP Exercises : Get the directory path used for temporary file
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
