JSON Question

PHP: Loop through json comparing current time with time range based on two keys values

I'm basically trying to make an epg viewer based on some json data.

I need some help to figure out how to:


  1. Loop through the json data.

  2. Get the "start" and "stop" values (unix timestamps) of each program.

  3. Make a time range for each program based on the start/stop
    timestamps.

  4. Compare the time range of each program with the current unix time.

  5. Display the program which has a time range that fits the current time.



This is what the json data looks like:

This is the PHP I have so far: (I know it isn't much. I just don't know how to go on from here)

<?php
$channel = '1';
$current_unix = time();
$json = json_decode(file_get_contents('http://tvtid-app-backend.tv2.dk/api/tvtid/v1/dayviews/'.date('Y-m-d').'?ch='.$channel), true);
$programs = $json[0]['programs'];
$programs_length = count($programs);
for ($i = 0; $i < $programs_length ; $i++)
{
$begin = [$programs[$i]['start']];
$end = [$programs[$i]['stop']];
$title = [$programs[$i]['title']];
}
?>


And this how the output should look: (Example time is 16:41)

<ul>
<li class="program">
<div class="title_now">TV AVISEN med Sporten og Vejret</div>
<div class="duration_now">
<div class="now_begin">16:30</div><span class="begin">1476030600</span>
<div class="progress_bar"><div class="progress"></div></div>
<div class="now_end">17:00</div><span class="end">1476032400</span></div>
</li>
<li class="program">
<div class="title">Guld i Købstaden - en hurtig handel</div>
<div class="duration">17:00-17:05</div>
</li>
<li class="program">
<div class="title">Atlanterhavet: Verdens vildeste hav</div>
<div class="duration">17:05-18:00</div>
</li>
<li class="program">
<div class="title">Bedrag II</div>
<div class="duration">18:00-19:00</div>
</li>

etc...

</ul>


I hope this makes sense and that someone is able to help me out.

Answer

It is far simpler using foreach to process over a complete array.

$channel = '1';
$current_unix = time();

// note I have removed the TRUE option from json_decode()

$json = json_decode(file_get_contents('http://tvtid-app-backend.tv2.dk/api/tvtid/v1/dayviews/'.date('Y-m-d').'?ch='.$channel));
//print_r($json);

echo '<ul>';

foreach ($json as $data) {

    echo '<li>';
    foreach ($data->programs as $prog) {

        if ( $current_unix < $prog->start ) {

            // add your own HTML instead of the simple echo
            echo $prog->title . '<br>';
            echo $prog->start . '<br>';
            echo $prog->stop . '<br>';
            echo $prog->id . '<br>';
            if ( isset($prog->category)) {
                echo $prog->category . '<br>';
            }
        }
    }
    echo '</li>';
}
echo '</ul>';
