PHP Time / Date message evaluation

Hello ... Im trying to implement a status message based on the day of the week and time of day

ie:

if Sunday -> display "We are closed"
if Saturday between the hours of 0800 and 1800 -> display "We are open"
if Mon-Fri between the hours of 0800 and 1800 -> display "We are open"
else display "We are closed"

It works fine when i use either the day of week or the time of day, but it is giving odd results when i try to implement the two together.

heres what i have so far
$current_day = date(l);

if ($current_day == "Sunday") {
echo "Closed";
}
elseif ($current_day == "Saturday" && date('H') > 8 && date("H") < 19) {
echo "Open";

elseif ($current_day != "Saturday" || $current_day != "Sunday" || date("H") < 8) {
echo "Closed";

elseif ($current_day != "Saturday" || $current_day != "Sunday" && date("H") > 18) {
echo "Closed"
}

Open in new window


it seems like its hitting the day evaluation and stopping there.

Any suggestions?

The parameter of the date function is a string, you need quotes around your l.

$current_day = date("l");

It looks like you are missing your closing braces for the elseif statements


$current_day = date(l);

if ($current_day == "Sunday") {
echo "Closed";
}
elseif ($current_day == "Saturday" && date('H') > 8 && date("H") < 19) {
echo "Open";
}
elseif ($current_day != "Saturday" || $current_day != "Sunday" || date("H") < 8) {
echo "Closed";
}
elseif ($current_day != "Saturday" || $current_day != "Sunday" && date("H") > 18) {
echo "Closed"
}

You could also try...

if (date("H") > 8 && date("H"<18){
$status = "Open";
}else{
$status = "Closed";
}
if(date("l")=="Sunday"){
$status = "Closed";
}
echo $status;

Have a look at this article.  I'll try to show you how I might code this.  (Actually I would probably use a data base, but maybe there is a straight PHP solution).

Maybe like this: http://www.laprbass.com/RAY_temp_nriddock.php
<?php // RAY_temp_nriddock.php
error_reporting(E_ALL);
echo "<pre>";

// PROBLEM DEFINITION
/*
if Sunday -> display "We are closed"
if Saturday between the hours of 0800 and 1800 -> display "We are open"
if Mon-Fri between the hours of 0800 and 1800 -> display "We are open"
else display "We are closed"
*/


// REQUIRED PHP 5.1+
date_default_timezone_set('America/Chicago');


// FUNCTION TO SAY IF WE ARE OPEN
function areWeOpen($datetime='Now')
{
    // TABLE OF HOURS OF OPERATION
    static
    $hop
    = array
    ( 'Sun' => FALSE
    , 'Mon' => array ('a' => '0800', 'z' => '1800')
    , 'Tue' => array ('a' => '0800', 'z' => '1800')
    , 'Wed' => array ('a' => '0800', 'z' => '1800')
    , 'Thu' => array ('a' => '0800', 'z' => '1800')
    , 'Fri' => array ('a' => '0800', 'z' => '1800')
    , 'Sat' => array ('a' => '0800', 'z' => '1500') // CHANGED THIS ON PURPOSE FOR THE DEMO
    )
    ;

    // CONVERT FUNCTION ARGUMENT TO A UNIX TIMESTAMP OR FAIL ON ERROR
    if (!$ts = strtotime($datetime))
    {
        error_log("Bogus input to AreWeOpen($datetime)");
        return 'We have no idea if we are open or not!';
    }

    $day = date('D', $ts);
    $now = date('Hi', $ts);
    if ($hop[$day])
    {
        $hrs = $hop[$day];

        // LOOK FOR $now BETWEEN OPENING AND CLOSING
        if ($now >= $hrs['a'])
        {
            if ($now <= $hrs['z'])
            {
                return "We are open";
            }
        }
    }

    // NOT OPEN
    return "We are closed";
}


// A FUNCTION TO TEST THE FUNCTION
function testAreWeOpen($x='Now')
{
    echo PHP_EOL . $x . ' ' . AreWeOpen($x);
}


// RUN SOME TESTS TO SEE IF IT WORKS
testareweopen();
testareweopen('Sunday');
testareweopen('Saturday 3:00pm');
testareweopen('Saturday 3:01pm');
testareweopen('Tuesday 2:00pm');
testareweopen('Yesterday 1:35pm');
testareweopen('Yesterday 1:35am');
testareweopen('Tomorrow 1:35pm');
testareweopen('Tomorrow 1:35am');
testareweopen('Now+84000 seconds');
testareweopen('May 15, 2012 10:00am');
testareweopen('Foobar');
