In a multidimensional array, how do I replace a null key with "None" ?
Here is an example:
'None' → array(1) {
[""] => array(4) {
[0] => array(10) {
'store' → str•2 '11'
'supplier_number' → str•4 '6303'
}
Should look like:
'None' → array(1) {
'None' => array(4) {
[0] => array(10) {
'store' → str•2 '11'
'supplier_number' → str•4 '6303'
}
