How can PHP developers handle the "SAFE MODE Restriction" warning related to file access permissions, as seen in the provided Telnet output?

The "SAFE MODE Restriction" warning in PHP is related to file access permissions. To handle this warning, PHP developers can use the `is_readable()` and `is_writable()` functions to check if a file can be read or written to before attempting any file operations. This helps ensure that the script will not encounter any permission issues when accessing files. 

$file = 'example.txt';

if (is_readable($file) && is_writable($file)) {
    // Perform file operations here
    $handle = fopen($file, 'r');
    $content = fread($handle, filesize($file));
    fclose($handle);
} else {
    echo 'File is not readable or writable.';
}
