数组中同名的值 [英] Value with same name in Array

问题描述

我想检查数组中是否有同名的值，如果有一个同名的值，我怎样才能得到它.假设我有

I want to check is there a value with same name in array, if there is a value with same name, how can i get it. Let's say i have

    <?php
if (is_array(Yii::app()->session['cart_values']))
{
    foreach ( Yii::app()->session['cart_values'] as $value) {


?>

接下来是什么，再次遍历另一个包含 $files 名称的数组，并检查是否存在同名文件.

and what is next, again go through another array which contain $files name and check it if there is file with same name.

我尝试了几个解决方案，但没有得到它.

I try few solutions but not get it.

推荐答案

尝试这样的事情

<?php
if (is_array(Yii::app()->session['cart_values']))
{
    foreach ( Yii::app()->session['cart_values'] as $values) {
    // get the uniques (assuming that $values is an array)
    $uniques = array_unique($values);

     // get the common values on each arrays so you get the repeated values
     $union = array_diff($values, $uniques);
    }
}
?>

希望这会有所帮助.
