Why I get empty search result from array_search()?

PHP
1

I am trying to search multidimensional array but I get alwayes empty result. Here is my code:

public $tenant;
    
$this->tenant = array( 
    "store" => "grocery1",
    array(
        "station" => "st1", 
        "times" => array(
            "day" => "Monday", 
            "from1" => "8:00", 
            "to1" => "12:00", 
            "from2" => "13:00", 
            "to2" => "17:30"
        ),
        array(
            "day" => "Wednesday", 
            "from1" => "8:00", 
            "to1" => "13:00", 
            "from2" => "", 
            "to2" => ""
        ),
        array(
            "day" => "Friday", 
            "from1" => "8:00", 
            "to1" => "12:00", 
            "from2" => "13:00", 
            "to2" => "20:00"
        ),
        array(
            "day" => "Saturdays", 
            "from1" => "10:00", 
            "to1" => "13:00", 
            "from2" => "", 
            "to2" => ""
        ),
    )
);

$key = array_search( 
    "8:00", 
    array_column($this->tenant, 'from1')
);
echo $key;

The only element in the [0][‘times’] array is the first set (Monday) data. The rest of the sets are at indexes [0][0], [0][1], and [0][2].

I suspect you wanted to build the array as -

$this->tenant = array( 
    "store" => "grocery1",
    array(
        "station" => "st1", 
        "times" => array(
			array("day" => "Monday", 
				"from1" => "8:00", 
				"to1" => "12:00", 
				"from2" => "13:00", 
				"to2" => "17:30"
			),
			array(
				"day" => "Wednesday", 
				"from1" => "8:00", 
				"to1" => "13:00", 
				"from2" => "", 
				"to2" => ""
			),
			array(
				"day" => "Friday", 
				"from1" => "8:00", 
				"to1" => "12:00", 
				"from2" => "13:00", 
				"to2" => "20:00"
			),
			array(
				"day" => "Saturdays", 
				"from1" => "10:00", 
				"to1" => "13:00", 
				"from2" => "", 
				"to2" => ""
			),
		)
    )
);

You would then need to use the following array_column statement to access the values -

array_column($this->tenant[0]['times'], 'from1')

“from1” is column of $this->tenant[0].

Thanks but I still get empty search result

5

How exactly are you coming up with this array?

6

I am trying to use data for stores open hours to work on it

7

Not helpful. What is the source of this data and how does it end up in this array?

8

If you are getting a zero (0), that’s the key of the 1st ‘8:00’ in the data. If you are getting a false (which would not display when echoed), that would mean that the value wasn’t found.

9

source is example documentation. for example I have many stores and store 1 has these open hours, store 2 has another different open hours so I am the person who made this array to use it on some operations like decide open and close times.

10

The array is not constructed properly. Can you provide a link to the documentation you mention?

use it on some operations like decide open and close times

Can you please provide more details on this.

Here is the instructions:

Mondays, Tuesdays, and Thursdays from 8:00–12:00 and 13:00–17:30 Wednesdays from 8:00–13:00 Fridays from 8:00–12:00 and 13:00–20:00 Saturdays from 10:00–13:00

I need to send a time and get back if this store is closed or opened

12

We are getting there…

Is this to determine if a store is open for the current date and time or checking some random day and time? What is the high level overview of what you are doing?

Thanks. I just need to send a timestamp with date and time and I need to return open or close.

14

I was able to fix it to get the key now. But if I did this array in wrong way please advise.

Start here…
* Take note: Timezone is hard coded for Los Angeles

<?php

function storeIsOpen() {
    $status = FALSE;
    $storeSchedule = [
        'Mon' => ['08:00 AM' => '05:00 PM'],
        'Tue' => ['08:00 AM' => '05:00 PM'],
        'Wed' => ['08:00 AM' => '05:00 PM'],
        'Thu' => ['08:00 AM' => '05:00 PM'],
        'Fri' => ['08:00 AM' => '05:00 PM']
    ];

    //get current West Coast US time
    $timeObject = new DateTime('America/Los_Angeles');
    $timestamp = $timeObject->getTimeStamp();
    $currentTime = $timeObject->setTimestamp($timestamp)->format('H:i A');

    // loop through time ranges for current day
    foreach ($storeSchedule[date('D', $timestamp)] as $startTime => $endTime) {

        // create time objects from start/end times and format as string (24hr AM/PM)
        $startTime = DateTime::createFromFormat('h:i A', $startTime)->format('H:i A');
        $endTime = DateTime::createFromFormat('h:i A', $endTime)->format('H:i A');

        // check if current time is within the range
        if (($startTime < $currentTime) && ($currentTime < $endTime)) {
            $status = TRUE;
            break;
        }
    }
    return $status;
}

echo storeIsOpen() ? 'Store Open' : 'Store Closed';

Thanks friend benanamen

Hint: For multiple stores, pass the hours array as a parameter to the function like so…

function storeIsOpen($storeSchedule) 

echo storeIsOpen($storeSchedule1) ? 'Store Open' : 'Store Closed';
echo storeIsOpen($storeSchedule2) ? 'Store Open' : 'Store Closed';
echo storeIsOpen($storeSchedule3) ? 'Store Open' : 'Store Closed';
