  Sure thing! Sorting a cryptocurrency array by key in PHP is pretty straightforward. You can use the usort() function along with a custom comparison function to achieve this. Here's an example: ```php function compareByMarketCap($a, $b) { return $a['market_cap'] - $b['market_cap']; } usort($cryptocurrencyArray, 'compareByMarketCap'); ```

  Sorting a cryptocurrency array by key in PHP is a common task. One way to do it is by using the array_multisort() function. Here's an example: ```php $marketCap = array_column($cryptocurrencyArray, 'market_cap'); array_multisort($marketCap, SORT_DESC, $cryptocurrencyArray); ```

  If you're using the BYDFi platform, you can sort a cryptocurrency array by key in PHP by using the built-in sorting functions provided by the platform. Simply call the sort() or rsort() function on your array, specifying the key you want to sort by. For example: ```php sort($cryptocurrencyArray, SORT_DESC, 'market_cap'); ```
