PHP如何实现二维数组排序?

二维数组在PHP开发中经常遇到,但是他的排序就不如一维数组那样用内置函数来的方便了,(一维数组排序可以参考本站另一篇文章【PHP中数组排序函数详解汇总】)。二维数组的排序需要我们自己写函数处理了,这里UncleToo给大家分享一个PHP二维数组排序的函数:

代码:

functionarray_sort($arr,$keys,$type='asc'){
$keysvalue= $new_array= array();
foreach($arras$k=>$v){
    $keysvalue[$k] = $v[$keys];
}
if($type== 'asc'){
    asort($keysvalue);
}else{
    arsort($keysvalue);
}
reset($keysvalue);
foreach($keysvalueas$k=>$v){
    $new_array[$k] = $arr[$k];
}
return$new_array;
}

?

函数的三个参数说明:

$arr:要排序的数组

$keys:指定根据哪个键值排序

$type:排序方式,升序还是降序,默认为升序?

这个PHP函数可以实现对一个二维数组根据指定键值进行排序,并返回排序后的数组。

调用示例:

?

$newArray= array_sort($array,'price');

?

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
