[英]remove duplicates from the two array in php
我坚持以下删除数组重复的问题
$result=array(2) { [0]=> object(stdClass)#489 (5) { ["id"]=> string(2) "64" ["block_from_id"]=> string(3) "117" ["block_to_id"]=> string(3) "329" ["block_status"]=> string(1) "0" ["username"]=> string(5) "pppoo" } [1]=> object(stdClass)#490 (5) { ["id"]=> string(2) "65" ["block_from_id"]=> string(3) "117" ["block_to_id"]=> string(3) "590" ["block_status"]=> string(1) "0" ["username"]=> string(3) "Pet" } }
$customerlist= array(7) { [0]=> object(stdClass)#491 (5) { ["customer_name"]=> string(4) "User" ["profile_image"]=> string(47) "http://pet.huarisnaque.com/pet/upload/90113.png" ["jid"]=> string(18) "user128@canopus-pc" ["customer_id"]=> string(3) "128" ["phone"]=> string(10) "4784784784" } [1]=> object(stdClass)#494 (5) { ["customer_name"]=> string(6) "Khatru" ["profile_image"]=> string(46) "http://smartpetmanagement.com/upload/61694.png" ["jid"]=> string(20) "khatru321@canopus-pc" ["customer_id"]=> string(3) "321" ["phone"]=> string(10) "9686838386" } [2]=> object(stdClass)#495 (5) { ["customer_name"]=> string(5) "pppoo" ["profile_image"]=> string(46) "http://smartpetmanagement.com/upload/35210.png" ["jid"]=> string(17) "yyy329@canopus-pc" ["customer_id"]=> string(3) "329" ["phone"]=> string(10) "9525538835" } [3]=> object(stdClass)#496 (5) { ["customer_name"]=> string(7) "Xitxitx" ["profile_image"]=> NULL ["jid"]=> string(21) "xitxitx330@canopus-pc" ["customer_id"]=> string(3) "330" ["phone"]=> string(10) "6535383535" } [4]=> object(stdClass)#497 (5) { ["customer_name"]=> string(25) "The Following Document yf" ["profile_image"]=> string(46) "http://smartpetmanagement.com/upload/13712.png" ["jid"]=> string(39) "the following document yf589@canopus-pc" ["customer_id"]=> string(3) "589" ["phone"]=> string(10) "9535383535" } [5]=> object(stdClass)#498 (5) { ["customer_name"]=> string(3) "Pet" ["profile_image"]=> NULL ["jid"]=> string(17) "pet590@canopus-pc" ["customer_id"]=> string(3) "590" ["phone"]=> string(10) "6560530537" } [6]=> object(stdClass)#499 (5) { ["customer_name"]=> string(10) "Sanjay Pra" ["profile_image"]=> NULL ["jid"]=> string(24) "sanjay pra599@canopus-pc" ["customer_id"]=> string(3) "599" ["phone"]=> string(10) "2828282822" } }
有两个数组,我们需要从数组中删除重复的记录,该记录包含结果中两个元素,而结果中的顾客列表中的元素。 这是我的方法
for($i=0;$i<count($customerslist);$i++)
{
for($j=0;$j<count($result);$i++)
{
// if($result[$j]->block_to_id==$customerslist[$i]->customer_id)
{
unset($customerslist[$i]);
}
echo $result[$j]->block_to_id."<br/>";
}
}
找到具有重复的索引后,可以取消设置值。 因为如果在检查重复项的for循环中取消设置它,则将产生此错误,因为数组的大小/计数更改并且索引不再匹配:
注意:未定义的偏移量:2
所以我的解决方案是您可以将匹配的索引放在另一个数组上,然后在下面显示的另一个for循环上取消设置它们:
$result=array(
array('id' => 64,
"block_from_id" => 117,
"block_to_id" => 329,
"block_status" => 0,
"username" => "pppoo"),
array("id"=> 65,
"block_from_id"=> 117,
"block_to_id"=> 590,
"block_status"=> 0,
"username"=> "Pet"
)
);
$customerlist= array(
array("customer_name" => "User" ,"profile_image" => "http://pet.huarisnaque.com/pet/upload/90113.png" ,"jid" => "user128@canopus-pc" ,"customer_id" => "128" ,"phone" => "4784784784"),
array("customer_name" => "Khatru" ,"profile_image" => "http://smartpetmanagement.com/upload/61694.png" ,"jid" => "khatru321@canopus-pc" ,"customer_id" => "321" ,"phone" => "9686838386"),
array("customer_name" => "pppoo" ,"profile_image" => "http://smartpetmanagement.com/upload/35210.png" ,"jid" => "yyy329@canopus-pc" ,"customer_id" => "329" ,"phone" => "9525538835"),
array("customer_name" => "Xitxitx" ,"profile_image " => NULL ,"jid" => "xitxitx330@canopus-pc" ,"customer_id" => "330" ,"phone" => "6535383535"),
array("customer_name" => "The Following Document yf" ,"profile_image" => "http://smartpetmanagement.com/upload/13712.png" ,"jid" => "the following document yf589@canopus-pc" ,"customer_id" => "589" ,"phone" => "9535383535"),
array("customer_name" => "Pet" ,"profile_image " => NULL ,"jid" => "pet590@canopus-pc" ,"customer_id" => "590" ,"phone" => "6560530537"),
array("customer_name" => "Sanjay Pra" ,"profile_image " => NULL ,"jid" => "sanjay pra599@canopus-pc" ,"customer_id" => "599" ,"phone" => "2828282822")
);
echo "Before:". sizeof($customerlist) ."<br>";
print_r($customerlist);
echo "<br>";
echo "<br>";
$match = array();
for ($i=0; $i < sizeof($result) ; $i++) {
for ($ii=0; $ii < sizeof($customerlist) ; $ii++) {
if ($result[$i]['block_to_id'] == $customerlist[$ii]['customer_id']) {
$match[] = $ii;
echo " Match INDEX on result $i == customerlist $ii<br>";
}
}
}
for ($i=0; $i < sizeof($match) ; $i++) {
$ii = $match[$i];
unset($customerlist[$ii]);
}
echo "<br>";
echo "After: ". sizeof($customerlist) ."<br>";
print_r($customerlist);
输出:
