PHP, UI/UX Design | What does unexpected T_DOUBLE_ARROW means in PHP programming?

Sample PHP error statement

PHP: Parse error: syntax error, unexpected T_DOUBLE_ARROW in .\rvunits_controller.php on line 152

It is a syntax error in the coding. Check the line number indcated in the error to see how the values have been assigned to variables. There should be an array that should have been used in that place and the value assignment seems to happen outside the said boundaries – like “xyz” => “name” should be changed to array(“xyz” => “name”) instead.
