  Sure! You can use the usort() function in PHP to sort the array based on a specific key value. Here's an example code snippet: $currencyArray = [ ['name' => 'Bitcoin', 'price' => 50000], ['name' => 'Ethereum', 'price' => 3000], ['name' => 'Litecoin', 'price' => 150] ]; function sortByPrice($a, $b) { return $a['price'] - $b['price']; } usort($currencyArray, 'sortByPrice'); This code will sort the array in ascending order based on the 'price' key value. You can modify the sortByPrice() function to sort based on other key values as well. Hope this helps!

  No problem! You can use the array_multisort() function in PHP to achieve this. Here's an example code snippet: $currencyArray = [ ['name' => 'Bitcoin', 'price' => 50000], ['name' => 'Ethereum', 'price' => 3000], ['name' => 'Litecoin', 'price' => 150] ]; $price = array_column($currencyArray, 'price'); array_multisort($price, SORT_ASC, $currencyArray); This code will sort the array in ascending order based on the 'price' key value. You can modify the SORT_ASC parameter to sort in descending order. I hope this helps!

  You can use the ksort() function in PHP to sort the array by key value. Here's an example code snippet: $currencyArray = [ 'BTC' => ['name' => 'Bitcoin', 'price' => 50000], 'ETH' => ['name' => 'Ethereum', 'price' => 3000], 'LTC' => ['name' => 'Litecoin', 'price' => 150] ]; ksort($currencyArray); This code will sort the array by the keys in ascending order. If you want to sort in descending order, you can use krsort() instead. I hope this helps! If you have any further questions, feel free to ask.
