  One efficient method to sort a PHP array of cryptocurrencies by key is to use the array_multisort() function. This function allows you to sort multiple arrays or a multi-dimensional array by one or more columns. In your case, you can use it to sort the array of cryptocurrencies by their keys. Here's an example: ``` $keys = array_keys($cryptocurrencies); array_multisort($keys, $cryptocurrencies); ```

  If you prefer a more object-oriented approach, you can use the uasort() function in PHP. This function allows you to define a custom comparison function to sort the array. Here's an example: ``` function compareKeys($a, $b) { return strcmp($a['key'], $b['key']); } uasort($cryptocurrencies, 'compareKeys'); ```
