PHP shortest/longest string length in array

Question

I have an array like this

$data = array(
    "163",
    "630",
    "43",
    "924",
    "4",
    "54"
);

How can I select the smallest and largest values from it according to string length NOT number value. (for this example it is 1 (smallest) and 3 (largest).

Answer 1

Seems like you should use an array_map()

  // Convert array to an array of string lengths
$lengths = array_map('strlen', $data);

  // Show min and max string length
echo "The shortest is " . min($lengths) .
     ". The longest is " . max($lengths);

Note that the $lengths array is unsorted, so you can easily retrieve the corresponding number for each string length.
