没有数组键

Question

Hey I'm trying to get the key of my array in a foreach. But got this error Warning: array_keys() expects parameter 1 to be array, string given on line 10

Here is my array:

$status_de = array
(
    '1' => 'Anfrage',
    '2' => 'Angebot',
    '3' => 'Abgeschlossen'  
);

Here is my code:

<select name="land">
    <?php foreach ($status_de as $status) {
      echo "<option value='" . array_keys($status) . "'>" . $status . "</option>";
    }
    ?>
</select>

Answer 1

You should use:

<?php foreach ($status_de as $key=>$status) {
  echo "<option value='" . $key . "'>" . $status . "</option>";
}
?>

as array_keys() will return array containing all keys (so not applicable to use with strings operators)
