php multidimension array dynamically - php

Question

This is the static multidimension array and i converted to json.
$mailmsg = array(
'type'=> 'line',
'data' => array(
'labels' => array("1","2","3","4","5"),
'datasets' => array(array("label"=>"A","fill"=>"false","yAxisID"=>"A","borderColor"=>"#bae755","data"=>array(100, 96, 84, 76, 69)),array("label"=>"B","fill"=>"false","yAxisID"=>"B","borderColor"=>"#55bae7","data"=>array(1, 1, 1, 1, 0)),array("label"=>"C","fill"=>"false","yAxisID"=>"C","borderColor"=>"#e755ba","data"=>array(5, 15, 10, 10, 0)))),
' '=>array("scales"=>array("yAxes"=>array(array("scaleLabel"=>array("display"=>"true","labelString"=>"Prn1"),"id"=>"A","type"=>"linear","position"=>"left"),array("scaleLabel"=>array("display"=>"true","labelString"=>"Prn2"),"id"=>"B","type"=>"linear","position"=>"left"),array("scaleLabel"=>array("display"=>"true","labelString"=>"Prn3"),"id"=>"C","type"=>"linear","position"=>"left")))
));
echo $json = json_encode((object)$mailmsg, JSON_NUMERIC_CHECK);
Result:
{
"type": "line",
"data": {
"labels": ["1","2","3","4","5"],
"datasets": [{
"label": "A",
"fill": "false",
"yAxisID": "A",
"borderColor": "#bae755",
"data": [100, 96, 84, 76, 69]
}, {
"label": "B",
"fill": "false",
"yAxisID": "B",
"borderColor": "#55bae7",
"data": [1, 1, 1, 1, 0]
}, {
"label": "C",
"fill": "false",
"yAxisID": "C",
"borderColor": "#e755ba",
"data": [5, 15, 10, 10, 0]
}]
},
"options": {
"scales": {
"yAxes": [{
"scaleLabel": {
"display": "true",
"labelString": "Prn1"
},
"id": "A",
"type": "linear",
"position": "left"
}, {
"scaleLabel": {
"display": "true",
"labelString": "Prn2"
},
"id": "B",
"type": "linear",
"position": "left"
}, {
"scaleLabel": {
"display": "true",
"labelString": "Prn3"
},
"id": "C",
"type": "linear",
"position": "left"
}]
}
}
}
I need to above static array to change dynamically using foreach.

Answer 1

just pass the reference to the specific data in the array:
foreach($mailmsg['data']['datasets'] as $key => $value){
}
