在PHP中通过整数索引访问关联数组

Question

I want to set the value of an associative array using the array index of the key/value pair. For example:

$my_arr = array( "bling" => "some bling", "bling2" => "lots O bling" );
$my_arr[1] = "not so much bling";  // Would change the value with key bling2.

How can this be accomplish this without using the key string?

Answer 1

Use array_keys.

$keys = array_keys($my_arr);
$my_arr[$keys[1]] = "not so much bling";

Hope this helps.
