Replace two dots ".." to dereference operator "->"

Probably the easiest way would be to add something like this to your user keybinds file:

{ "keys": [".", "."], "command": "insert_snippet", "args": {"contents": "->"}, "context": [ { "key": "selector", "operator": "equal", "operand": "source.php" } ] }

it is not working,

Well try just

{ "keys": [".", "."], "command": "insert_snippet", "args": {"contents": "->"} }

and ensure you have a comma between every {"keys"...} section.

many thanks Joel

what other users use this like functionalty while writing their OOP PHP script?

or they type as "-" key then ">" key (but it's to slow)
