Re: [PHP] best way to save program prefs to a file?
In larger applications, I prefer to serialize the array because it allows
you to store the data in _any_ variable, not just the pre-named variable.
For example, if your page is already using a variable named $user_settings,
you would run into problems with your solution. My solution allows you to
name the data however you want, however many times you want.
Of course, this is usually not necessary for a smaller application where you
wouldn't run into such a problem.

Hope this helps.
I may be showing my ignorance here, but why bother to serialize the array?
Why not just write it out to a php file, then all you have to do is
include the file when you need it and it's ready to go?
$setingsFile = " $val)
{
$settingsFile .= "$userSettings[$key] = $val\n";
}
$settingsFile .= "\n?>";
$fh = fopen('/path/to/settingsFile.php', 'w');
fwrite($fh, $settingsFile); // with error handling of course...
fclose($fh);
Then in your script, include '/path/to/settingsFile.php'; and you're ready
to use $userSettings and any changes get written back to the file.

Write a regular Windows .ini file like: ; My INI-file (this is a comment line): key = value key2 = value2 ; It even works with PHP constants (defines) in the ini file key3 = E_ALL Reading it in is simple, use parse_ini_file(): http://www.php.net/manual/en/function.parse-ini-file.php You can also keep sections in the .ini file such as: ; a section name uses [] [section1] key = value [section2] key = value To write this down is easy, just do a foreach on your associative array and write to a string that you then save into a file if you wish to update the values here.
