I save signs in array like this: ["151:75:213:Factions"]=> array(2) { ["rank"]=> string(5) "Owner" ["cost"]=> string(3) "500" } using unset($this->signs['151:75:213:Factions']); Does not remove it.
Example: PHP: $array=['string0', 'string1', 'string2'];unset($array[array_search('string1', $array)]);
