PCRE uses hyphens to indicate character ranges instead of '..',
so you probably want

  $PageTextVarPatterns['var::'] = 
    '/^([-a-zA-Z_]+)\\s*::[ \\t]?(.*)$/m';

Perhaps

  $PageTextVarPatterns['var::'] =
    '/^([-a-zA-Z_]+)\\s*::[ \\t]?(.*?)\\s*$/m';

And I'm assuming that you're deliberately not allowing digits
in your page text variables... if you want digits also, then

  $PageTextVarPatterns['var::'] =
    '/^(\\w[-\\w]*)\\s*::[ \\t]?(.*?)\\s*$/m';

This last version also prevents a page text variable from
beginning with a hyphen.
