问题描述

我有一个数组,需要按另一个数组的形式对2个字段的邮政编码进行排序并批准

我可以按邮政编码对其进行排序,但无法在批准的字段中进行排序,例如

我需要按60007,60001,60003,60002排序(按照类似排序的顺序)

  $ sortLike = array(60007,60001,60003,60002);$ array1 =数组(数组('ID'=> 138,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 103,'zip_code'=> 60007,'approved'=> 0),array('ID'=> 114,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 105,'zip_code'=> 60003,'approved'=> 0),array('ID'=> 124,'zip_code'=> 60002,'approved'=> 0)) 

因此,60007和经过批准的版本应该比带有0(未批准)的60007和所有60001批准的版本都要比未经批准的所有60001优先(依 $ sortlike 依此类推),这里是完整的php代码

 <?php$ array1 =数组(数组('ID'=> 138,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 103,'zip_code'=> 60007,'approved'=> 0),array('ID'=> 114,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 105,'zip_code'=> 60003,'approved'=> 0),array('ID'=> 124,'zip_code'=> 60002,'approved'=> 0),array('ID'=> 104,'zip_code'=> 60002,'approved'=> 1),array('ID'=> 106,'zip_code'=> 60001,'approved'=> 0),array('ID'=> 188,'zip_code'=> 60022,'approved'=> 0),array('ID'=> 184,'zip_code'=> 60022,'approved'=> 1),);函数sort_results($ a,$ b){$ sortLike = array(60007,60001,60003,60002);如果(!in_array($ a ['zip_code'],$ sortLike)){返回1;}//将未知值推入数组的末尾返回array_search($ a ['zip_code'],$ sortLike)>array_search($ b ['zip_code'],$ sortLike);}usort($ array1,'sort_results');回声< pre>";print_r($ array1);回声</pre>"; 
解决方案

我想您是在问如何也可以按'approved'进行排序,因为您的代码当前缺少该信息./p>

此问题的解决方案是定义一个检查输入数组 $ array1 的键的顺序.

因此,您首先需要检查 zip_code .如果得到结果!= 0,则可以立即返回.但是,如果结果为== 0(邮政编码相等),则需要检查第二个密钥(本例中为'approved').

  $ array1 =数组(数组('ID'=> 138,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 103,'zip_code'=> 60007,'approved'=> 0),array('ID'=> 114,'zip_code'=> 60007,'approved'=> 1),array('ID'=> 105,'zip_code'=> 60003,'approved'=> 0),array('ID'=> 124,'zip_code'=> 60002,'approved'=> 0),array('ID'=> 104,'zip_code'=> 60002,'approved'=> 1),array('ID'=> 106,'zip_code'=> 60001,'approved'=> 0),array('ID'=> 188,'zip_code'=> 60022,'approved'=> 0),array('ID'=> 184,'zip_code'=> 60022,'approved'=> 1),);函数sort_results($ a,$ b){$ sortLike = array(60007,60001,60003,60002);如果(!in_array($ a ['zip_code'],$ sortLike)){返回1;}//将未知值推入数组的末尾$ zip_res = array_search($ a ['zip_code'],$ sortLike)-array_search($ b ['zip_code'],$ sortLike);//检查邮政编码顺序if($ zip_res == 0){//如果邮政编码相等$ zip_res = $ b ['approved']-$ a ['approved'];//按批准"键排序}返回$ zip_res;} 

//编辑

您可以使用lamda函数将 $ sortLike 移出该函数(需要PHP> = 5.3):

  $ sortLike = array(60007,60001,60003,60002);$ sort_results =函数($ a,$ b)use($ sortLike){//创建带有"use"关键字的lambda函数如果(!in_array($ a ['zip_code'],$ sortLike)){返回1;}//将未知值推入数组的末尾$ zip_res = array_search($ a ['zip_code'],$ sortLike)-array_search($ b ['zip_code'],$ sortLike);if($ zip_res == 0){$ zip_res = $ b ['approved']-$ a ['approved'];}返回$ zip_res;};usort($ array1,$ sort_results);//在中传递lambda函数回声< pre>";print_r($ array1);回声</pre>";死(); 

I have array that I need to sort by another array form 2 fields zip code and approve

I am able to sort it by zip code but unable to do it with approved field so for eg

I need to sort by 60007,60001,60003,60002 (as per sortlike order)all zip code from 60007 and approved should come first so

$sortLike=array(60007,60001,60003,60002);
$array1= array(
    array ('ID' => 138,'zip_code' => 60007,'approved' => 1),
    array('ID' => 103,'zip_code' => 60007,'approved' => 0),
    array('ID' => 114,'zip_code' => 60007,'approved' => 1),
    array('ID' => 105,'zip_code' => 60003,'approved' => 0),
    array('ID' => 124,'zip_code' => 60002,'approved' => 0)
)

so 60007 and aproved should come first than 60007 with 0(unapproved) and than all 60001 approved than all 60001 unapproved(and so on as per $sortlike) here is complete php code

<?php
$array1= array(
    array ('ID' => 138,'zip_code' => 60007,'approved' => 1),
    array('ID' => 103,'zip_code' => 60007,'approved' => 0),
    array('ID' => 114,'zip_code' => 60007,'approved' => 1),
    array('ID' => 105,'zip_code' => 60003,'approved' => 0),
    array('ID' => 124,'zip_code' => 60002,'approved' => 0),
    array('ID' => 104,'zip_code' => 60002,'approved' => 1),
    array('ID' => 106,'zip_code' => 60001,'approved' => 0),
    array('ID' => 188,'zip_code' => 60022,'approved' => 0),
    array('ID' => 184,'zip_code' => 60022,'approved' => 1),
);
function sort_results ($a, $b) {
   $sortLike=array(60007,60001,60003,60002);
   if (!in_array ($a['zip_code'], $sortLike)) { return 1; } // Push unknown values at the end of the array
   return array_search($a['zip_code'], $sortLike) > array_search($b['zip_code'], $sortLike);
}

usort ($array1, 'sort_results');
echo "<pre>";
print_r($array1);
echo "</pre>";
解决方案

I guess you're asking how you can also sort by 'approved', because that is currently missing in your code.

The solution to this question is to define an order in which the keys of your input array $array1 are checked.

So you need to check zip_code at first. If you get a result != 0, you can return immediately. But if the result is == 0 (the zip codes are equal) you need to check the second key ('approved' in your case).

$array1= array(
    array ('ID' => 138,'zip_code' => 60007,'approved' => 1),
    array('ID' => 103,'zip_code' => 60007,'approved' => 0),
    array('ID' => 114,'zip_code' => 60007,'approved' => 1),
    array('ID' => 105,'zip_code' => 60003,'approved' => 0),
    array('ID' => 124,'zip_code' => 60002,'approved' => 0),
    array('ID' => 104,'zip_code' => 60002,'approved' => 1),
    array('ID' => 106,'zip_code' => 60001,'approved' => 0),
    array('ID' => 188,'zip_code' => 60022,'approved' => 0),
    array('ID' => 184,'zip_code' => 60022,'approved' => 1),
);
function sort_results ($a, $b) {
    $sortLike=array(60007,60001,60003,60002);
    if (!in_array ($a['zip_code'], $sortLike)) { return 1; } // Push unknown values at the end of the array
    $zip_res = array_search($a['zip_code'], $sortLike) - array_search($b['zip_code'], $sortLike); // check zip_code order
    if($zip_res == 0){ // if the zip_codes are equal
        $zip_res = $b['approved'] - $a['approved']; // sort by the 'approved' key
    }
    return $zip_res;
}

//edit

You can use a lamda function to move $sortLike out of the function like this (requires PHP >= 5.3):

$sortLike=array(60007,60001,60003,60002);
$sort_results = function ($a, $b) use ($sortLike){ // create lambda function with "use" keyword
    if (!in_array ($a['zip_code'], $sortLike)) { return 1; } // Push unknown values at the end of the array
    $zip_res = array_search($a['zip_code'], $sortLike) - array_search($b['zip_code'], $sortLike);
    if($zip_res == 0){
        $zip_res = $b['approved'] - $a['approved'];
    }
    return $zip_res;
};

usort ($array1,$sort_results); // pass lambda function in
echo "<pre>";
print_r($array1);
echo "</pre>";
die();
