Conditional based on day of week and time range

I'm trying to find a solution to a conditional based on the day of the week and a time range within that day. I've managed to hunt down the code for the day of the week but I can't find how to incorporate a time frame within the day?

For example: 

IF today is Monday AND between 2pm and 4pm THEN do THIS

This is what I have...

<?php   
date_default_timezone_set('Australia/Perth'); // PHP supported timezone
$script_tz = date_default_timezone_get();
// get current day:
$currentday = date('l'); ?>
<?php if ($currentday == Monday){ ?>
Monday
<?php } elseif ($currentday == Tuesday){ ?>
Tuesday
<?php } elseif ($currentday == Wednesday){ ?>
Wednesday
<?php } elseif ($currentday == Thursday){ ?>
Thursday
<?php } elseif ($currentday == Friday){ ?>
Friday
<?php } elseif ($currentday == Saturday){ ?>
Saturday
<?php } elseif ($currentday == Sunday){ ?>
Sunday
<?php } else { ?>
<?php } ?>

I'm not sure if this may help for the time frame? Check day of week and time

All the conditions packed into an array is easier for maintenance.

A simplified example:

$ranges = [
  ['Monday',12,14, function(){echo "do something";}],
  ['Tuesday',12,14, function(){echo "do something on Tue";}],
  //: more
];

$curWeekDay = date('l');
$hours = date("G");
foreach($ranges as $range){
  if($curWeekDay == $range[0] AND $hours >= $range[1] AND $hours < $range[2]){
    $range[3]();
  }
}

Output on Tue 13:25:

do something on Tue

This code here checks a DateTime is between a start and end time.

<?php

$date = new DateTime('2019-11-18 12:49');

$start = new DateTime('2019-11-18 09:00');
$end = new DateTime('2019-11-18 17:00');

if ($date > $start && $date < $end) {
    echo 'In the zone!';
}

Note.

$date->format('l'); will return Monday or whatever day it is.

$date->format('H:i'); will return 13:15 or whatever time it is.

You'd better user date('N') as it is not language dependant and date('H') to take advantage of the 24h format that is better fit for time comparison.

function date_in_frame($test_date, $day, $start, $end){
    $d = new Datetime($test_date);
    return $d->format("N") == $day && $d->format("H") >= $start && $d->format("H") < $end;
}
//test if "now" is Monday between 2pm (14:00) and 4pm (15:59)
var_dump(date_in_frame("now", 0, 14, 16));

Basically this:

<?php

if (date('l') === 'Monday' && date('G') >= 2 && date('G') < 4) {
    // do something
}

You were missing quotes around the day names.

The condition I wrote will evaluate to true on Monday between 2 PM and 4 PM (while 4 PM itself will not, e.g. the last allowed values is 3:59 PM).

you could use different date/time components to streamline the code:

function between($value, $start, $end)
{
    return $value > $start && $value <= $end;
}

$hours = date("G");

switch( date("N"))
{
    case 1:  //monday
        if (between($hours,12 + 2,12 + 4 )) //using 24h format to avoid checking am/pm
        {
            // IF today is Monday AND between 2pm and 4pm THEN do THIS
        }
    break;

    case 2: //tuesday
    break;


    //....

}
