问题描述

嗨!



如何计算阵列的数量?请看例子。我通过一个例子更容易解释。



示例:

Hi!

How can I count the quantity of an array? Please see example. It is easier for me to explain through an example.

Example:

$_SESSION['products'] = array('123', '123', '456', '456', '456', '789', '789', '789', '789');



显示应为:


Display should be:

Item | Qty.
123  | 2
456  | 3
789  | 4 

推荐答案

_SESSION [' products'] = array(' 123'' 123' 456'' 456' ' 456'' 789'' 789'' 789'' 789') ;
_SESSION['products'] = array('123', '123', '456', '456', '456', '789', '789', '789', '789');



显示应该是:


Display should be:

Item | Qty.
123  | 2
456  | 3
789  | 4

foreach(
countedStuff = NULL; foreach(
