php parse_ini_string() fix
<?php
/*
php parse_ini_string() extension
With function below you can:
- fix unvalued fields ('key' (invalid) ==> 'key=' (OK) )
- fix unquotted values with equal sign '=' ('key=value_part1=value_part2' ==> 'key="value_part1=value_part2"')
- fix (solve) multidimensional arrays (makes 'key[key1][key2]=value' valid)
- fix any reading errors (wrong lines, they may be later rawurldecoded with md5 checking)
