PHP通过多维数组循环

Question

Hi I have this multi dimensional array in PHP:

$team_arrays = array (
                        "lakers" => array (
                                        24 => "Bryant",
                                        6  => "Price",
                                        17 => "Lin"
                        ),

                        "knicks" => array (
                                        7 => "Anthony",
                                       22 => "Shumpert",
                                       12 => "Jackson"
                        ),

                        "thunder" => array (
                                       35 => "Durant",
                                       0  => "Westbrook",
                                       13 => "Miller"
                        )
                    );

I wanted to display something like this:

Team Name: lakers

1. Bryant = 24
2. Price = 6
3. Lin = 17

Team Name: knicks

1. Anthony = 7
2. Shumpert = 22
3. Jackson = 12

...

This is the code that I tried but seems not to work:

foreach ($team_arrays as $names => $team) {
                        echo "<h2>Team Name: " . $names . "</h2>";
                        echo "<ol>";
                            foreach ($team_arrays as $jersey => $names) {
                                echo "<li>" . $names . " = " . $jersey . "</li>";
                            }
                        echo "</ol>";
                    }

It generates this kind of error

Notice: Array to string conversion in

Would anyone tries for a help. Please.

I found this solution from other question but seems I can't relate to it.

Answer 1

There is only one small problem in your code

foreach ($team_arrays as $jersey => $names) {
         ^ // again looping over the same outer array?

That inner loop is wrong, you should loop over $team and not $team_arrays because your outer loop picks up each team using $team variable.

foreach ($team as $jersey => $names) {

Rest of your code and logic is already fine.
