Question

Is there a way to represent/pass a multidimensional array like

array( array('foo' => 'bar') , array('language' => 'php'), ...);

into a GET string?

For simple arrays such as

array(1,2,3,4)

I can represent it like this

?ids=1,2,3,4

But I don’t know how to represent multidimensional arrays

Answer 1

There’s several ways you could do it.

One way is to serialize() it and then unserialize() it on the page that reads it.

Another way is to json_encode() it and then json_decode() it on the page that reads it.

Or, in keeping with the CSV-style it sounded like you prefer, you could just delimit the next layer of the array with a different delimiter, ex.

array(
    0 => array(1, 2, 3),
    1 => array(4, 5, 6),
)

becomes

?array=1|2|3,4|5|6

Finally, PHP will also parse arrays in the querystring like:

?array[0][0]=1&array[0][1]=2&array[0][1]=3&array[1][0]=4&array[1][1]=5&array[1][1]=6
