Turn off all error reporting generated by PHP
Replace “$os” with the more descriptive “$operating_system”
The closing PHP XML tag is not needed
Emphasize the use of an encrypted drive in setup message
Remove “chmod” function
Convert path to “config.php” to a variable structure
Replace hard-code path to “config.php” with its variable equivalent
Add one white space character around function argument
Add CSS class “.error”
Add an ID to the form with an associated CSS rule set
Replace “file_put_contents” with “fopen” and “fwrite”
------------------------------------------------------------------------
PHP’s “file_put_contents” is the equivalent to “fopen,” “fwrite,” and
“fclose,” but I want more control over which function fails (for error
reporting reasons). Thus the use of “fopen” and “fwrite.”
Add forward slash to full config file path
Form styling is now done with “#create-passwords-database-form” so this is not needed
Remove superfluous newline
Close the config file immediately after writing to it
Align closing </form> tag
