I am trying to convert a multidimensional array into a string.
Till now I have been able to convert a pipe delimited string into an array.
Will render into the following array:
$x = array( 'group' => array( 'key' => 'value', 'key_second' => 'value' ), );
However, now I want it to be the other way around, where a multidimensional array is provided and I want to convert it to a pipe delimited string just like in the first code example.
Any ideas how to do this ?
PS: Please do note that the array can dynamically have any depth.
$x['group']['sub_group']['category']['key'] = 'value'
