I’ve got a dictionary where both the keys and values are strings. I would like to print each key-value pair on its own line with the key left justified and the value right justified.
Key1 Test Key2 BlahBlah
Etc…
What’s the best way to do this in PHP? Perhaps a clever way to do with printf?

Answer
Try this:
printf("%-40s", "Test");
The 40
tells printf to pad the string so that it takes 40 characters (this is the padding specifier). The -
tells to pad at the right (this is the alignment specifier).
See the conversion specifications documenation.
So, to print the whole array:
$max_key_length = max(array_map('strlen', array_keys($array))); $max_value_length = max(array_map('strlen', $array)); foreach($array as $key => $value) { printf("%-{$max_key_length}s %{$max_value_length}sn", $key, $value); }
