FOREACH with a DATE COMPARE condition (PHP) - php

Question

I have a JSON source and I am trying to loop trough it and show some results (up to 9 results) which is not a problem
The problem is that I want to show only the results that are matching a certain date, where the date might be exact or between 2 dates.
For example I want to show only the events where let say the date 2019-11-17 is within timeFrom timeTo of the event or timeFrom or timeTo is equal to it. In that example it will be event 1 and 3
This is the source sample
{
"title":"event 1",
"timeFrom":"2019-11-16 19:00:00",
"timeTo":"2019-11-18 22:00:00",
"listText":"text of the event",
"url":"https://url",
"imageUrl":"https://image.jpg",
"locations":{
"title":"Location name",
"url":"https://location"
}
},
{
"title":"event 2",
"timeFrom":"2019-11-20 19:00:00",
"timeTo":"2019-11-20 22:00:00",
"listText":"text of the event",
"url":"https://url",
"imageUrl":"https://image.jpg",
"locations":{
"title":"Location name",
"url":"https://location"
}
},
{
"title":"event 3",
"timeFrom":"2019-11-17 19:00:00",
"timeTo":"2019-11-17 22:00:00",
"listText":"text of the event",
"url":"https://url",
"imageUrl":"https://image.jpg",
"locations":{
"title":"Location name",
"url":"https://location"
}
And this is the foreach I have at the moment
foreach(array_slice($arr, 0, 9) as $data) {
//then I will show the result
}
So, I can't figure out how to make that condition within the foreach.

Answer 1

This function iterates through the events data, looking for events whose from and to dates surround the given date:
function find_events($events, $date) {
$date = new DateTime($date);
foreach ($events as $event) {
$from = (new DateTime($event['timeFrom']))->setTime(0,0,0);
$to = (new DateTime($event['timeTo']))->setTime(0,0,0);
if ($date >= $from && $date <= $to) {
echo "{$event['title']} ({$event['listText']}) from {$event['timeFrom']} to {$event['timeTo']}\n";
}
}
}
$events = json_decode($json, true);
find_events($events, '2019-11-17');
Output:
event 1 (text of the event) from 2019-11-16 19:00:00 to 2019-11-18 22:00:00
event 3 (text of the event) from 2019-11-17 19:00:00 to 2019-11-17 22:00:00

Try this code:
$date = "2019-11-17";
$events = json_decode($json_output, true);
foreach ($events as $event)
{
if (($date > $event['timeFrom'] && $date < $event['timeTo']) || in_array($date, array($event['timeFrom'], $event['timeTo'])))
{
$filtered_events[] = $event;
}
}
$sliced_events = array_slice($filtered_events, 0, 9);
print_r($sliced_events);
