How can one fix the "Permission denied" error in PHP related to file access?

The "Permission denied" error in PHP related to file access occurs when the script does not have the necessary permissions to read, write, or execute a file. To fix this issue, you can check and adjust the file permissions using the chmod function in PHP. Ensure that the script has the appropriate permissions to access the file by setting the correct permissions. 

// Check and adjust file permissions
$filename = 'example.txt';
if (file_exists($filename)) {
    chmod($filename, 0644); // Set read and write permissions for owner, read-only for others
    echo "File permissions adjusted successfully.";
} else {
    echo "File does not exist.";
}
