<?php
function morgen($vandaag) {
$dagen = array ('ma','di', 'wo','do', 'vr', 'za', 'zo');
return $dagen[$vandaag];
}
echo morgen(2);
echo "<br>";I am new on Php. I called (wo) and I wanna call the next one (vr) how can I do that?
The next one after Wednesday is Thursday…
anyway i guess you should increase the $vandaag value
$vandaag++;
But what if your on the last day? Day number 6 or sunday? Then tomorrow will be day 0 or monday. So you must add an overflow protection.
while($vandaag > 6) {
$vandaag -= 7;
}
The whole function should then look like this
function morgen($vandaag) {
$dagen = array ('ma','di', 'wo','do', 'vr', 'za', 'zo');
$vandaag++;
while($vandaag > 6) {
$vandaag -= 7;
}
return $dagen[$vandaag];
}
[edit]
date(´w´) gives a numeric representation of the day of the week 0 (for Sunday) through 6 (for Saturday). To use that you should start wit Sunday in your array and ending with Saturday.
Now you are using the ISO-8601 numeric representation of the day of the week. But that one starts with one instead of zero. In that case you could forget the $vandaag++; rule and change the while condition to while($vandaag > 7)

So, what is the actual problem rather than your attempted solution?
If you just want to find out what tomorrow is,
function tomorrow() {
$date = new DateTime();
return $date->modify('+1 day');
}
echo tomorrow()->format('Y-m-d');
// outputs 2020-05-27
