But they user could have used \/ which is valid, but your "fix" denies
him this possibility. I wouldn't add an extra test, but use @ in the
test and maybe add a not to the TS error stack for the admin panel.

Simpel change for readability:

if (preg_match('|^/.+/$|', $needle))

Preferred change that allows / and | to be used as regexp "brackets":

if (preg_match('#^/.+/$|^.+|$#', $needle))
