Hi,
Say I have an array containing a reference to itself:
$myArray = array();
$myArray['self'] =& $myArray;
How can I, looping iteratively through the array, detect the fact that
$myArray['self'] will "take" me to where I have already been? The print_r()
and var_dump() functions print *RECURSION* in such a case (though only after
the "second round"). Setting a flag seems to be the only solution, but I
don't want to modify the array in question - I want to produce a visual
representation of its contents like var_dump(), but formatted to my taste. I
had considered parsing the output of var_dump(), but first, that format
might change in a future version of PHP and second, an array key might be a
string resembling part of the output (like $myArray['["myArray"]=>']), which
seems to be difficult to detect by the parsing code.
Is there another way of doing this?
Greetings,
Thomas
