Question

我有一个数组，我想聚合其中的每个单词并计算它们，如下：

 Array
    (
        [0] => Notice
        [1] => co
        [2] => co
        [3] => Notice
        [4] => co
        [5] => co
        [6] => sls
    )

应如下所示：

Array
(
    [Notice] => 2
    [co] => 4
    [sls] => 1
)

这样做的方法是什么？

感谢

Answer 1

您需要查看array_count_values()

<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>

输出：

Array
(
    [1] => 2
    [hello] => 2
    [world] => 1
)

Answer 2

试试这样：

<?php
$array = array("Notice", "co", "co", "Notice", "co", "co", "sls");
print_r(array_count_values($array));
?>

输出

Array
(
    [Notice] => 2
    [co] => 4
    [sls] => 1
)
