Get values from custom array using php

Question

I have got the below array

Array
(
    [0] => Array
        (
            [0] => Contact Number
            [1] => 35443545
        )

    [1] => Array
        (
            [0] => Address
            [1] => vvvv
        )

)

I would like to display as

Contact Number
35443545
<hr>
Address
vvvv

My code

foreach($address_box_content as $k=>$address)
{
    echo '<h2>'.$address[$k].'</h2><p>'.$address[$k+1].'</p>';
}

But for some reason it is printing the first 2 lines and then displaying a notice 'Undefined offset:2'

echo '<h2>'.$address[0].'</h2><p>'.$address[1].'</p><hr>'; — t3chguy

Should rename your vars, name $address to $property and it will be more clear — DarkBee

What you have is an array. One whose elements are (also) arrays. Each array that you have stored has 2 elements, 0 and 1.

When you loop, $k is the index of the main (outer) array. Its value doesn't make any sense in the inner array. You just need to loop over the outer array, and print the 0 and 1 elements from the inner one.

foreach($address_box_content as $address)
{
    echo '<h2>'.$address[0].'</h2><p>'.$address[1].'</p>';
}

Well you're getting undefined offset error because you're using $k which is the index of the outer array

You can do something like:

foreach($address_box_content as $addresses){
    foreach($addresses as $address){
        echo '<h2>', $address, '</h2><p>', $address, '</p>';
    }
}

And if you want to get the index of inner array:

foreach($address_box_content as $addresses){
    foreach($addresses as $key => $address){
        echo '<h2>', $address[$key], '</h2><p>', $address[$key], '</p>';
    }
}

This is your array 
$data = Array
(
    [0] => Array
        (
            [0] => Contact Number
            [1] => 35443545
        )

    [1] => Array
        (
            [0] => Address
            [1] => vvvv
        )

)
simple way to print array 
for($i=0;$<count($data);$i++)
{
  echo  "<h2>".$data[$i][$0]."</h2>"."<p>".$value[$i][1]."</p>"."<hr />";
}

well, for each element you define a key and a value which are $k and $address.

$k will be 0 and 1, $address will be 0 and 1, and then 0 and 1.

the undefined offset error is because you call $k plus 1 that on the second foeach iteration try to access to position 1+1 (2) doesn't find anything.

you could use something like:

foreach($address_box_content as $data => $value) {

    echo    "<h2>" . $value[0] . "</h2>"
          . "<p>" . $value[1] . "</p>"
          . "<hr />";

}
