I did some research and tried using the below code, but it return something else.
foreach($elements as $key => $value) {
echo $value['label'];
echo $value['id'];
}
Kindly help me out.
CodePudding user response:
With such structure of array you should iterate twice:
foreach ($elements as $key => $value) {
foreach ($value['elements'] as $element) {
echo $element['label'];
echo $element['id'];
}
}
