Spent some time figuring out what "recursive" means in the contect of the 
function. So maybe instead of $local_table it can be just $table.

As for the code: lots of tests with trigraphs if $local_table is non-empty? 
Why? The SQL will be broken anyway if it isn't. If you do want a check do a 
"if ($local_table==='' || $mm_table==='') { rerurn FALSE; }" at the beginning.

And commenting the name: the "_rec_" part is perhaps misleading as it it is 
currently mostly used as a shorthand for "record". Please use "recursive" 
(unless you rename it, see above why).
