Question

Having problems getting the right data out of this multidimensional(?) array that I retrieve when using FirePHP to see what I’m working with:

array(
    ['day'] => 'Wed'
    ['is_used'] => 1
    [0] =>
    array(
        ['day'] =>
        'Wed'
        ['title'] =>
        'onsdag denna veckan 2'
        ['content'] =>
        ['price'] =>
    )
    [1] =>
    array(

        ['day'] =>
        'Wed'
        ['title'] =>
        'onsdagslunchen'
        ['content'] =>
        ['price'] =>
        123123
    )
)

I want to use the 0, 1 array in the array if that makes any sense…? Or is this array broken?

When I try

foreach ($foo as $bar){
    echo $bar
}

I’m getting 4 results, day, is_used and the 0, 1 arrays.

The code is returning the values correctly. It’s returning the first children of the $foo array, which are:

day
is_used
0
1

day and is_used are strings, but because 0 and 1 are arrays, you’ll need to cycle through them again to get their values:

foreach ($foo as $fooKey=>$bar){
    if(is_array($bar))
        // cycle through the array
        foreach ($bar as $key=>$value)
            // Echo out the string of the array
            echo "$fooKey $key = $value<br />";
        }
    } else {
        // Echo out the string
       echo "$fooKey = $bar<br />";
    }
}

That should echo out the following:

day = Wed
is_used = 1
0 day = Wed
0 title = onsdag denna veckan 2
0 content =
0 price =
1 day = Wed
1 title = onsdagslunchen
1 content =
1 price = 123123
