问题描述

在PHP中,我必须比较一个整数变量是否小于数组的值,但是我在代码中出错并偶然发现了意外行为。

In PHP I had to compare if an integer variable was less than a value of an array, but I had an error in the code and I found by chance an unexpected behavior.

我正在将整数与数组本身进行比较,并且返回真。你知道为什么吗?

I was comparing the integer with the array itself and it was returning true. Do you know why?

我一直在StackOverflow和php.net中搜索此内容(PHP类型比较),但我没有找到具体的答案。

I've been searching about this in StackOverflow and php.net (PHP types comparisons) and I didn't found a specific answer.

这里有一些代码可以对此进行测试。

Here you have a little code to test this.

<?php

$myArray = array();
$myInt = 1;

if($myInt < $myArray){
    echo "Int less than array\n";
}

if($myInt == $myArray){
    echo "Int equal to array\n";
}

if($myInt > $myArray){
    echo "Int greater than array\n";
}

我为 $ myInt $ myArray 的不同内容,它总是打印以下内容:

I've tried different values for $myInt and different contents for $myArray and it always prints this:

Int less than array


推荐答案

数组对其他任何数组的结果总是大于数组:

Comparing an array to anything else result in array is always greater :

请参阅php doc-与各种类型的比较
