PHP looping over multidimensional array with key

Question

I have an array with different arrays in them with values. I want to loop over these arrays inside to get all the values but for some reason It only goes over the first array.

Here's what the array looks like: This array's name is slots.

Array
(
    [41] => Array
        (
            [0] => Array
                (
                    [attractie] => attractie1
                    [start] => 0930
                    [end] => 1200
                    [personen] => 
                    [catering] => 1
                    [bedrijfsnaam] => attractie1
                    [link] => http:
                    [color] => dd0330
                )

            [1] => Array
                (
                    [attractie] => attractie1
                    [start] => 1000
                    [end] => 1230
                    [personen] => 
                    [catering] => 1
                    [bedrijfsnaam] => Bedrijf2
                    [link] => http:
                    [color] => e49fca
                )
        )

    [52] => Array
        (
            [0] => Array
                (
                    [attractie] => attractie2
                    [start] => 0930
                    [end] => 1030
                    [personen] => 
                    [catering] => 1
                    [bedrijfsnaam] => Bedrijf4
                    [link] => http:
                    [color] => f7e300
                )

            [1] => Array
                (
                    [attractie] => attractie2
                    [start] => 0930
                    [end] => 1030
                    [personen] => 
                    [catering] => 0
                    [bedrijfsnaam] => bedrijf5
                    [link] => http:
                    [color] => f78f1e
                )

        )

)

So this is what my loop looks like:

$i=0;
foreach($slots[$attractieIDs[$i]] as $s){

        $myOrders[] = array( 'attractie' => $s['attractie'],
                             'name' => $s['bedrijfsnaam'],
                             'start' => $s['start'],
                             'end' => $s['end'],
                             'link' => $s['link'], 
                             'personen' => $s['personen'],
                             'catering' => $s['catering'],
                             'color' => $s['color'],
                           ); 
         $i++;
}

attractieID is an array with the id's in them the (41 and 52).

When I print out $myOrders I only get to see the values of the array with id 41 it doesn't go to the next array with a new id.

Anyone knows how I can fix this?

Many thanks in advance!

I would like to output the values of the array with id 52 as well — Frank Lucas

Just all the values(name, attractie, etc.) of every item in all the arrays in my big $slots array — Frank Lucas

Man why don't you put desired array structure in your question.? — Death-is-the-real-truth

Your current code will merge entries from 41 and 52 into one array and you will not be able to tell which one was which.

$sourceArray = .... your source array here :)
$attractieIDs = array(41, 52);

foreach($attractieIDs as $id) {
   foreach($sourceArray[$id] as $attr) {
     $myOrders[] = $attr;
   }
}

I get an Illegal offset type and Invalid argument supplied for foreach() error

Marcin Orlowski Over a year ago

Forgot one level. Try now.

trincot Over a year ago

@MarcinOrlowski, I retract my previous comment, however there is something wrong: you should only need 2 loops. Now you will only get values, no keys, since $s is not an array.

trincot Over a year ago

This seems wrong (unless the OP has been very unclear in expressing), because this does not give you the keys "attractie", "bedrijfsnaam", "start".... Only their values are returned in one big array. I put your code here.

Death-is-the-real-truth Over a year ago

Also don't it will restrict because of $attractieIDs = array(41, 52);? what happen if lot of other indexes will come? how much indexes will be hardcoded?

You could use this:

foreach ($attractieIDs as $id) {
    foreach ($slots[$id] as $s) {
        $myOrders[] = $s;
    }
}

See it run on eval.in

Try this loop:

foreach($slots as $outer_arr){

    foreach($outer_arr as $s) {
        $myOrders[] = array( 'attractie' => $s['attractie'],
              'name' => $s['bedrijfsnaam'],
              'start' => $s['start'],
              'end' => $s['end'],
              'link' => $s['link'], 
              'personen' => $s['personen'],
              'catering' => $s['catering'],
              'color' => $s['color'],
        ); 

    }


}

But still not clear with your desired output.

What should $outer_arr be?

Meathanjay Over a year ago

The $outer_arr will contain the array with index 41 and 52 and one more foreach loop for iterate over the array.

If you can add array variable NOT array output I can test it.

Try this one. This loop will output any value inside your array regardless on what index you have.

<?php
$test = array(
    '41' => array( 
        array('attractie' => 'attractie1',
             'start' => '0930',
             'end' => '1200',
             'personen' => NULL,
             'catering' => '1',
             'bedrijfsnaam' => 'attractie1',
             'link' => 'http:',
             'color' =>'dd0330'),
        array('attractie' => 'attractie1',
             'start' => '1000',
             'end' => '1230',
             'personen' => NULL,
             'catering' => '1',
             'bedrijfsnaam' => 'Bedrijf2',
             'link' => 'http:',
             'color' =>'e49fca'),
            ),
    '51' => array( 
        array('attractie' => 'attractie2',
             'start' => '0930',
             'end' => '1030',
             'personen' => NULL,
             'catering' => '1',
             'bedrijfsnaam' => 'Bedrijf4',
             'link' => 'http:',
             'color' =>'f7e300'),
        array('attractie' => 'attractie2',
             'start' => '0930',
             'end' => '1030',
             'personen' => NULL,
             'catering' => '0',
             'bedrijfsnaam' => 'bedrijf5',
             'link' => 'http:',
             'color' =>'f78f1e'),
            )
    );

foreach ($test as $a => $val) {
    echo "<b>Index $a</b><br><br>";
    foreach ($val as $b) {
        foreach ($b as $key => $value) {
            echo "<b>$key</b> - $value<br>";
        }
    }
    echo "<br><br>";
}
?>

Output:

Index 41

attractie - attractie1
start - 0930
end - 1200
personen - 
catering - 1
bedrijfsnaam - attractie1
link - http:
color - dd0330
attractie - attractie1
start - 1000
end - 1230
personen - 
catering - 1
bedrijfsnaam - Bedrijf2
link - http:
color - e49fca


Index 51

attractie - attractie2
start - 0930
end - 1030
personen - 
catering - 1
bedrijfsnaam - Bedrijf4

attractie - attractie2
start - 0930
end - 1030
personen - 
catering - 0
bedrijfsnaam - bedrijf5
