I would like to read and write user-settings to a keyword-value file and be
able to extract it. The following code works fine but i wondered if there
was a more elegant/direct way of doing this.
-Durwood
$file = "user_settings.txt";
// Read user settings from file if it exists, otherwise set to defaults and
// save them ... a separate method exists for users to change their
settings.
if ($is_readable($file)) {
$parm = read_defaults($file);
} else {
$parm['method'] = "bsort";
$parm['tsize'] = 200;
$parm['per_row'] = 5;
$parm['sortby'] = "last_name";
$parm['order'] = "ascending";
write_defaults($file, $parm);
}
// Read keyword-value pairs from file into array
function read_defaults($default_file) {
$fp = file($default_file);
foreach ($fp as $line) {
$line = trim($line);
list ($key, $value) = explode(" ", $line);
$param[$key] = $value;
}
return $param;
}
// Write keyword-value pairs from array
function write_defaults($default_file, $param) {
$fp = fopen($default_file, "w");
while (list($key, $value) = each ($param))
fwrite ($fp, "$key $value\n");
fclose($fp);
}
