The insecure solution: make lcd4linux a set-uid-root program
(   chmod u+s `which lcd4linux`    should do the trick)

The secure solution: write a very small and obviously correct
program that starts and stops lcd4linux depending on the existance
of a file (or better input from a socket). Now let your PHP
script manipulate that file  (or output to the socket).
