[SOLVED] PHP getdate echo if yday equals

PHP getdate echo if yday equals

Using PHP getdate(); I get the following array output:

Array (
    [seconds] => 54 
    [minutes] => 26 
    [hours] => 19 
    [mday] => 10 
    [wday] => 5 
    [mon] => 12 
    [year] => 2021 
    [yday] => 343 
    [weekday] => Friday 
    [month] => December 
    [0] => 1639164414
)

I want to use if the value [yday] equals a particular number then echo message but unsure how this can be done. The idea is to have a different message echo each day - I know how to do this in JavaScript but been tasked with doing it in PHP which is something I'm still learning.

For example if yday = 100 echo message, if yday = 200 echo different message.

So, if there is 365 days in a year I simply want to output (echo) a different message every day of the year based on the yday number. It doesn't need to be an exact time/zone, the message must stay static and we don't want it to be random, or use cookies with random to store it for 24 hours.

There might even be a better way of doing this without yday, any help appreciated.

Solution

Create an array of messages you want to show for each day, with the day number as key. Then print the message for that day:

<?php

$messages = [
    0 => 'foo bar',
    1 => 'hello world',
    100 => 'message',
    200 => 'different message',
    343 => 'lorem ipsum',
];

$today = getdate();
$yday = $today['yday'];
echo $messages[$yday];
