Test #1: PHP 5.3-5.6 Implement reading from file and print out info like in an example. Your function must do: - Read from file - Split data by rows into an array - Filter the array in such a way that only rows containing only numbers remain in it - Summarize the numbers in each line - Sort the received amounts in descending order - Return the result Code example: # Path to the file $file = __DIR__ . '/datalist.txt'; # Passing the data to the function that returns the result $result = getResult( $file ); # Printing result echo '<pre>'; var_export( $result ); function getResult ( $file ) { # @TODO Your code... } Output example: array ( 82 => 16396, 19 => 16169, 71 => 15864, 73 => 15224, 81 => 14244 ...
