使用php在多维数组中删除和插入重复元素的计数

我有一套多维数组的借书

排列 ( [0]=>阵列 ( [投标]=>1 [begindate]=>2015-02-03 [标题]=>编程 )

)

我已经有了删除副本的代码

0: begindate: "2015-02-03", bid: "1",title: "programming"    
3: begindate: "2015-02-03", bid: "4", title: "english"    
4: begindate: "2015-02-04"bid: "4"title: "english"

我想要的是在数组中插入重复的计数，这样我就可以得到这样的结果

0: begindate: "2015-02-03", bid: "1",title: "programming", count:"3"    
3: begindate: "2015-02-03", bid: "4", title: "english", count:"1"    
4: begindate: "2015-02-04", bid: "4", title: "english", count:"2"

这并不漂亮，但这会满足你的要求：

//main array here is $books
$clean = array();
foreach($books as $k1=>$v1){
    $exists = false;
    //does an entry already exist in $clean?
    foreach($clean as $k2=>$v2){
        if($v1["begindate"]==$v2["begindate"]&&$v1["bid"]==$v2["bid"]&&$v1["title"]==$v2["title"]){
            $exists = $k2;
            break;
        }
    }
    if($exists===false){
        //begin count, insert
        $v1["count"] = 1;
        array_push($clean,$v1);
    }else{
        //increment count
        $clean[$exists]["count"]++;
    }
}
print_r($clean);

只需使用一个容器来保存计数，每次重复出现时递增重复数据消除代码是什么？如果你只是简单地使用一个索引数组，那么很容易：每次遇到重复的数组时，只需增加

count

。粘贴你的代码即可删除重复的数组。我只需这样做代码sir$data=array\u map（“unserialize”，array\u unique（array\u map（“serialize”），array\u unique（array\u map（“serialize”），$data））；副本应以起始日期和投标日期为基础。对不起，我只是一个处理多维数组的初学者

//main array here is $books
$clean = array();
foreach($books as $k1=>$v1){
    $exists = false;
    //does an entry already exist in $clean?
    foreach($clean as $k2=>$v2){
        if($v1["begindate"]==$v2["begindate"]&&$v1["bid"]==$v2["bid"]&&$v1["title"]==$v2["title"]){
            $exists = $k2;
            break;
        }
    }
    if($exists===false){
        //begin count, insert
        $v1["count"] = 1;
        array_push($clean,$v1);
    }else{
        //increment count
        $clean[$exists]["count"]++;
    }
}
print_r($clean);
