似乎您应该使用

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);

请注意，$lengths数组未排序，因此您可以轻松地为每个字符串长度检索相应的数字.

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