separate data from a api - php

Question

we are trying to make a website for our class, here you can see important news, the class schedule, homework schedule and a contact page for tips and bugs...
So, we want to have the schedule always up to date and a class mate made a api to get the schedule-data from our school site. but now we have an issue... he don't want to help us anymore!!! -,-
here is the question?
The schedule is echo in a table but it stand next to eachother, because the api only separate the days including the lesson. but we want the lesson seperate from the day! and echo the table below each other..
Is there anyone who want to help me / Us out???

}
$i++;
}
array_push($opgeschoond, $tmp);
}
print(json_encode($opgeschoond));
?>
this we use the echo the data!!!!!
<table>
<tr>
<?php
foreach ($maandag as $lesuur)
{
print("<td>");
print($lesuur);
print("</td>");
}
?>
</tr>
<tr>
<?php
foreach ($dinsdag as $lesuur)
{
print("<td id='oneven'>");
print($lesuur);
print("</td>");
}
?>
</tr>
<tr>
<?php
foreach ($woensdag as $lesuur)
{
print("<td>");
print($lesuur);
print("</td>");
}
?>
</tr>
<tr>
<?php
foreach ($donderdag as $lesuur)
{
print("<td id='oneven'>");
print($lesuur);
print("</td>");
}
?>
</tr>
<tr>
<?php
foreach ($vrijdag as $lesuur)
{
print("<td>");
print($lesuur);
print("</td>");

thanks for helping me, a beginner (a)

Answer 1

The data returned from the 'api' is a two dimensional array, with the second dimension variable width, but the first entry is the day. data[0][0] = "Maandag 09-11-2015";.
If I understand correctly, what you want is something like this:
$apidata = file_get_contents($apiurl);
$data = json_decode($apidata, true);
$maandag = array_slice($data[0],1)
$dinsdag = array_slice($data[1],1)
$woensdag = array_slice($data[2],1)
$donderdag = array_slice($data[3],1)
$vrijdag = array_slice($data[4],1)
Then your echo from above will work, the day names removed from the arrays (though also the dates).
Once in this form, building a table for the days is relatively simple (though I'm sure others will have a cleaner way to do it):
<?php
$longest = 0;
for($i=0;$i<5;$i++) {
if($data[$i].count()>$longest) $longest=$data[$i].count();
}
$longest--; // we removed one entry already
?>
<table>
<tr><th>Maandag</th><th>Dinsdag</th><th>Woensdag</th><th>Donderdag</th><th>Vrijdag</th></tr>
<?php
for($i=0;$i<$longest;$i++) {
print "<tr><td>{$maandag[$i]}</td><td>{$dinsdag[$i]}</td><td>{$woensdag[$i]}</td><td>{$donderdag[$i]}</td><td>{$vrijdag[$i]}</td></tr>\n";
}
?>
</table>
That should have you set. There may be runtime errors attempting to access the array entries of the shorter days before the longest day is finished, but you can fix that with another loop adding empty strings.
