What steps can be taken to ensure that temporary files created during file uploads are readable by PHP?

When files are uploaded to a PHP server, temporary files are created in a temporary directory. To ensure that these temporary files are readable by PHP, you can set the correct permissions on the temporary directory where these files are stored. By setting the correct permissions, PHP will be able to read and process these temporary files without any issues.

// Set the correct permissions on the temporary directory
$tempDir = sys_get_temp_dir();
chmod($tempDir, 0755);
