PHP Array to JSON -> Adding Value Names - php

Question

PHP Script Snippet (only one holiday):
<?PHP
function calculateBankHolidays($yr) {
$bankHols = Array();
// New year's:
switch ( date("w", strtotime("01-01-$yr 12:00:00")) ) {
case 6:
$bankHols[] = "03-01-$yr";
break;
case 0:
$bankHols[] = "02-01-$yr";
break;
default:
$bankHols[] = "01-01-$yr";
}
// Good friday:
$bankHols[] = date("d-m-y", strtotime( "+".(easter_days($yr) - 2)." days", strtotime("21-03-$yr 12:00:00") ));
// Easter Monday:
$bankHols[] = date("d-m-y", strtotime( "+".(easter_days($yr) + 1)." days", strtotime("21-03-$yr 12:00:00") ));
// May Day:
if ($yr == 1995) {
$bankHols[] = "08-05-1995"; // VE day 50th anniversary year exception
} else {
switch (date("w", strtotime("01-05-$yr 12:00:00"))) {
case 0:
$bankHols[] = "02-05-$yr";
break;
case 1:
$bankHols[] = "01-05-$yr";
break;
case 2:
$bankHols[] = "07-05-$yr";
break;
case 3:
$bankHols[] = "06-05-$yr";
break;
case 4:
$bankHols[] = "05-05-$yr";
break;
case 5:
$bankHols[] = "04-05-$yr";
break;
case 6:
$bankHols[] = "03-05-$yr";
break;
}
}
return $bankHols;
}
header('Content-Type: application/json');
$bankHolsThisYear = calculateBankHolidays(2017);
echo (json_encode($bankHolsThisYear, JSON_PRETTY_PRINT));
?>
Result:
[
"02-01-2017",
"14-04-17",
"17-04-17",
"01-05-2017",
"2017-05-29",
"2017-08-28",
"2017-12-25",
"2017-12-26"

Desired Outcome:
{
"Holiday Name": {
"Start Date": ,
"End Date": ,
"Holiday type": ,
"Where it is observed": ,
},
Questions:
How do I add a "Holiday Name" to the parent of each value?
How do I add "Start Date" to each current value?

Answer 1

You could create an multidimensional associative array of objects and do something like:
$listOfHolidays=array(
'halloween'=>array('start'=>'10-31','end'=>'10-31','type'=>'trick or treat','celebratedBy'=>'childhood'),
'newYear'=>array('start'=>'12-31','end'=>'01-01','type'=>'new year','celebratedBy'=>'everyone'),
);
echo json_encode($listOfHolidays);
Tested: this is my output:
{
"halloween":
{"start":"10-31",
"end":"10-31",
"type":"trick ortreat",
"celebratedBy":"childhood"
},
"newYear":
{"start":"12-31",
"end":"01-01",
"type":"new year",
"celebratedBy":"everyone"
}
}
EDIT: as you commented about a switch, i'm not sure i understand the precision but you can easily get the 'holidays' by using the associative keys like so:
$boo=$array['halloween'];
And then get the value from this holiday with:
$boo['type']; //trick ortreat
OR you could alternativly get the value straight from the original array:
echo $array['newYear']['end']; //01-01
further more you can also add a value to the array:
$array['newYear']['bonus']='300$';
Also, just a friendly reminder that you can resotre the aray from jason simply by using the TRUE switch in json_decode like so:
$array=json_decode($json,true);
As for the switch, still i don'T see how you could be using a switch unless you loop through the holidays:
foreach($array as $k=>$v){
switch($k){
case 'halloween': echo $v['end']; break; //10-31
case 'newYear': echo $v['bonus']; break; //300$
default: echo 'normal work day'; break;
}
}
Hope this helps.
