It works like a charm.
Thanks, Andrej

I know there must be a more elegant way with array_reduce or something, but
I would simply write a function called
function array_intersect_m($m_array) {
$intersection = $m_array[0];
for ($i=1; $i < count($m_array); $i++) {
$intersection = array_intersect($m_array[$i], $intersection);
}
return $intersection;
}
and put that into my library. O and while i'm at it, the array_reduce
way would prob be:
$m_array =
array(array("green","red","blue"),array("green","yellow","red"),array("green","red","purple"),array("green","red","yellow"));
array_reduce($m_array, 'array_intersect');
but this could be wrong, havent done much with these 'meta' functions.

Dear all,
I have to perform an intersection on array of arrays. The fact is
that php does not support intersection on multidimensional arrays.
So, the first simple example using only one dimensional arrays works
well:
$array1 = array("green", "red", "blue");
$array2 = array("green", "yellow", "red");
$array3 = array("green", "red", "purple");
$array4 = array("green","red","yellow");
$result = array_intersect($array1,$array2,$array3,$array4);
print_r($result);
And the result is: Array ( [0] => green [1] => red )
The question is how to perform intersection on the following structure:
$products =
array(array("green","red","blue"),array("green","yellow","red"),array("green","red","purple"),array("green","red","yellow"));
Thanks in advance for any suggestions.
Best, Andrej
