Php using unserialize() and serialize() changing values in a saved file
- by Doodle
I have a serialized array of values saved to a file and need to change the value of one of the variables. In the example I change the value of $two and then save the whole array back into the file with the new value.
Is there a more efficient way of altering just the single value with out having to read and write the entire file/array.
$data = file_get_contents('./userInfo');
$data = unserialize($data);
extract($data);
$two="this is a altered value";
$userData = array(
'one' => $one,
'two' => $two,
'three' => $three
);
$file=fopen("../userInfo",'w');
fwrite($file, $userData);
fclose($file);
