PHP array_column - how to keep the keys?
multidimensional-array, php, php-5.5
Solution
foreach(key($parameters) as $key)
{
print($key);
}
You can also store that result in other variables if desired.
And to show both keys and values try this:
foreach ($parameters as $key => $value) {
echo $key . ' = ' . $value . '<br>';
}
Problem
I'm having issues getting the key of `$items` using `array_column`. This is the `$items` array: ``` $items = array( 1 => [ "id" => 5 ], 3 => [ "id" => 6 ], 4 => [ "id" => 7 ], ); var_dump(array_column($items,"id")); ``` Result: ``` array (size=3) 0 => int 5 1 => int 6 2 => int 7 ``` How can I get the desired result below? ``` array (size=3) 1 => int 5 3 => int 6 4 => int 7 ```
