php - Unusual notation of passing by reference? -

-

in legacy php script found following line of code:

$cachelite =& ( "string" );

which provokes error:

parse error: syntax error, unexpected '(', expecting t_new or t_string or t_variable or '$'

is mistake or way of passing reference or else don't know. have enable/disable in php configuration in order work?

you can't assign reference literal value, or expression, in php; has reference variable. have no idea how line of code got there (why $cachelite being assigned random string anyway?) — mistake in legacy code.
