Sublim hit a null press TAB will automatically become Is_null (Var), how to turn off

Sublim hit the null press TAB will automatically become Is_null (Var), how to turn off?
Note: I am under the. php file. And I don't know if this is auto-complete or snippet. But I checked my snippet. There is no null in it, so it should be auto-complete? How do I turn this off?

Try turning off Auto Completion:

In the setting-User configuration file, add the following line:
"Auto_complete": false
