PHP计数对象的属性发生 [英] PHP count object property occurrences

问题描述

我有一个PHP对象如下图所示，所有我想知道什么的最简单的方法来获得对象的数量，其中财产的typeid = 3

 阵列
（
    [0] =＆GT; ABC对象
        （
            [ID] =＆GT; 13
            [TYPEID] =＆GT; 3
            [中将sortOrder] =＆GT; 0
        ）
    [1] =＆GT; ABC对象
        （
            [ID] =＆GT; 12
            [TYPEID] =＆GT; 2
            [中将sortOrder] =＆GT; 0
        ）
    [2] =＆GT; ABC对象
        （
            [ID] =＆GT; 14
            [TYPEID] =＆GT; 4
            [中将sortOrder] =＆GT; 0
        ）
    [3] =＆GT; ABC对象
        （
            [ID] =＆GT; 15
            [TYPEID] =＆GT; 3
            [中将sortOrder] =＆GT; 0
        ）
）
 

解决方案

一个简单的的foreach 计数器应该做的：

  $计数= 0;
的foreach（$数组作为$对象）{
    如果（$对象 - ＆GT; typeid的== 3）$计数++;
}
 

没有必要过分复杂的事情

I have a PHP object like below and all I want to know whats the the easiest way to get a count of objects where the property 'typeId' = 3

Array
(
    [0] => ABC Object
        (
            [id] => 13
            [typeId] => 3
            [sortOrder] => 0
        )
    [1] => ABC Object
        (
            [id] => 12
            [typeId] => 2
            [sortOrder] => 0
        )
    [2] => ABC Object
        (
            [id] => 14
            [typeId] => 4
            [sortOrder] => 0
        )
    [3] => ABC Object
        (
            [id] => 15
            [typeId] => 3
            [sortOrder] => 0
        )
)

解决方案

A simple foreach counter should do:

$count = 0;
foreach ($array as $object) {
    if ($object->typeId == 3) $count++;
}

No need to over complicate things
