Extract associative array elements into individual variables

How do I go about setting a string as a literal variable in PHP? Basically I have an array like

$data['setting'] = "thevalue";

and I want to convert that 'setting' to $setting so that $setting becomes "thevalue".

extract() will take the keys of an array and turn them into variables with the corresponding value in the array.

See PHP variable variables.

Your question isn't completely clear but maybe you want something like this:

//Takes an associative array and creates variables named after
//its keys
foreach ($data as $key => $value) {
    $$key = $value;
}

It may be evil, but there is always eval.

$str = "setting";
$val = "thevalue";
eval("$" . $str . " = '" . $val . "'");
