Question

I have set up a multidimensional array in PHP like this:

$contents = array(
    "Header1" => array(
         "Section 1" => array (
               "Description1",
               "Notes1",
         ),
         "Gap" => "Gap",
         "Section 2" => array (
               "Description2",
               "Notes2",
         ),
         "Gap" => "Gap",
         "Section 3" => array (
               "Description3",
               "Notes3",
         ),
    ),
);

then I loop through this array as follows:

foreach ($contents as $header => $section) {
      foreach ($section as $title => $details) {
            echo $title."<br>";
      }
}

The output will be:

Section1
Gap
Section2
Section3

Why isn’t the second “Gap” showing?

Thanx

Answer 1

Because you can’t have duplicate array keys. The second one overwrites the first.

Use Gap2 or something for your next array key. Or, better yet, nest it:

array(
    'Gap' => array(
        'Gap1',
        'Gap2'
    )
);
