Hi!
We are testing PHP7.4 and there's a deprecated feature:
https://www.php.net/manual/es/migration74.deprecated.php#migration74.deprecated.core.array-key-exists-objects

So, in our system, the line https://github.com/austinhyde/IniParser/blob/master/src/IniParser.php#L197 is throwing this error:

Deprecated: array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in C:\inetpub\wwwroot\intranet\3rdparty\IniParser\vendor\austinhyde\iniparser\src\IniParser.php on line 197

Our idea, to fix it without too much research would be to implement a private method:

private static function array_key_exists($key_or_property, $array_or_class) { return is_object($array_or_class) ? property_exists($array_or_class, $key_or_property) : array_key_exists($key_or_property, $array_or_class); }

and replace all the array_key_exists calls for self::array_key_exists

Thank you very much in advance for your help!
