删除重复项,并设置有多少来自多维数组 [英] Remove duplicates and set how many there are from multi-dimensional array
问题描述
我是新来的StackOverflow,我需要一些帮助。
I'm new to stackoverflow and I need some help.
我想从PHP中的多维数组,如删除重复的:
I'm trying to remove the duplicates from a multi-dimension array in PHP such as:
阵列(
[0] =>阵列([开发平台] =>你好[数据] => 2015年1月1日[期限] => PHP
[全] => 1)
[0] => Array ( [Plat] => hello [Data] => 01/01/2015 [Term] => PHP [Quan] => 1 )
[1] =>阵列([开发平台] =>你好[数据] => 2015年1月1日[期限] => PHP
[全] => 1)
[1] => Array ( [Plat] => hello [Data] => 01/01/2015 [Term] => PHP [Quan] => 1 )
[2] =>阵列([开发平台] =>你好[数据] => 2015年3月1日[期限] => PHP
[全] => 1)
[2] => Array ( [Plat] => hello [Data] => 03/01/2015 [Term] => PHP [Quan] => 1 )
[3] =>阵列([开发平台] =>你好[数据] => 2015年3月1日[期限] => PHP
[全] => 1)
[3] => Array ( [Plat] => hello [Data] => 03/01/2015 [Term] => PHP [Quan] => 1 )
[4] =>阵列([开发平台] =>你好[数据] => 2015年3月1日[期限] => PHP
[定量] => 1)
[4] => Array ( [Plat] => hello [Data] => 03/01/2015 [Term] => PHP [Quant] => 1 )
[5] =>阵列([开发平台] =>你好[数据] => 2015年3月1日[期限] => PHP
[全] => 1)
[5] => Array ( [Plat] => hello [Data] => 03/01/2015 [Term] => PHP [Quan] => 1 )
)
和创建一个阵列,消除重复的并且发现这样会增加[拳]重复它的数量(通过数据过滤):
and create a array that removes the duplicates and adds to [Quan] the number of duplicates it as found like this (filtered by data) :
阵列(
[0] =>阵列([开发平台] =>你好[数据] => 2015年1月1日[期限] => PHP
[全] => 2)
[0] => Array ( [Plat] => hello [Data] => 01/01/2015 [Term] => PHP [Quan] => 2 )
[1] =>阵列([开发平台] =>你好[数据] => 2015年3月1日[期限] => PHP
[全] => 4)
[1] => Array ( [Plat] => hello [Data] => 03/01/2015 [Term] => PHP [Quan] => 4 )
)
我的code是如下因素:
$顶部是阵列。
My code is the folowing: $top is the array.
foreach($top as $value){
if(!empty($temp_top)){
for($i =0;$i<sizeof($temp_top);$i++){
if($value['Data'] == $temp_top[$i]['Data'] ){
$temp_top[$i]['Quan'] +=1;
}else{
$temp_top[] = $value;
}
}
}else{
$temp_top[] = $value;
}
}
我已经tryed一些答案,我发现这里的堆栈,如:
i've tryed some answers that I found here on stack such as:
$input = array_map("unserialize", array_unique(array_map("serialize", $top)));
但我不能添加多少有一些为[全] ..
but I can't add how many there are to [Quan]..
推荐答案
我找到了一个解决方案,我与其他职位的帮助。
I found a solution myself with the help of other posts.
下面是我的code的样本:
Here is a sample of my code:
$temp_top = array_map("unserialize", array_unique(array_map("serialize", $top)));
$numvezesfound=0;
foreach($temp_top as $key => $value){
for($i =0;$i<sizeof($top);$i++){
if($value['Data'] == $top[$i]['Data'] ){
$numvezesfound +=1;
}
}
$temp_top[$key]['Quan'] = $numvezesfound;
$numvezesfound = 0;
}
$top = $temp_top;
如果有人能帮助我使这个code更美丽,我会在你的债务:)
if someone can help me make this code more beautifull I would be in your debt :)
