PHP:按照值的长度对数组进行排序? 8个答案

I am new in php and i have an array like below

我是php的新手,我有一个如下所示的数组

$sv = array(
      "my name is john", // length 15
      "i am living in london from my childwood", // length 39
      "i am 13 years old", // length 17
      "i like to become software engineer in future" // length 44
);

Now i want to try to keep highest length value on top position in my array and lowest in the bottom of the array.

现在我想尝试在数组的顶部位置保持最高长度值,在数组底部保持最低值。

and my output will be

我的输出将是

Array
(
  [0] => i like to become software engineer in future
  [1] => i am living in london from my childwood
  [2] => i am 13 years old
  [3] => my name is john
)

If anyone can know the answer then please share it.

如果有人能够知道答案,请分享。

I think you should try

我想你应该试试

usort($sv, create_function('$a,$b','return strlen($b) - strlen($a);'));
