Php 为什么具有一个数组的多维数组与具有多个数组的多维数组不同?
我不确定我的措辞是否正确,但基本上,我有两个数组(见下文)。第一个数组只有一个“段”数组,但在执行var_转储时,它会显示它的子数组(或者根本不显示) 较大的数组有多个“段”数组,在var_转储中,可以看到数组(5) 背景是我从用php解码的json字符串中获取这两个数组 以下是阵列: Json: 数组:Php 为什么具有一个数组的多维数组与具有多个数组的多维数组不同?,php,arrays,json,multidimensional-array,Php,Arrays,Json,Multidimensional Array,我不确定我的措辞是否正确,但基本上,我有两个数组(见下文)。第一个数组只有一个“段”数组,但在执行var_转储时,它会显示它的子数组(或者根本不显示) 较大的数组有多个“段”数组,在var_转储中,可以看到数组(5) 背景是我从用php解码的json字符串中获取这两个数组 以下是阵列: Json: 数组: array(1) { ["css"]=> array(1) { ["segment"]=> array(3) { ["type"]=&g

我的问题是,当“段”中只有1个数组时,如何强制执行数组,或者为什么会发生这种情况
编辑:
我要问的是,为什么它在较小的数组中,只有一个“段”数组,我对它进行计数,如图3所示。它显示“注释”、“类型”和数组“规则”,它们都是“段”的子级。现在,在更大的数组中,有超过1个“段”行,计数为5,每个“段”都有一个带有“注释”、“类型”和数组“规则”的数组,而不是直接子数组。您可以共享json字符串吗?您可以发布您收到的json字符串吗?@JayD。您的
JSON
在值中包含值,因此它创建了一个多维数组
@JayD。每件事都完全按照它应该的那样工作。var_dump以这种方式表示数组,因为这就是json字符串的含义。我认为您误解了var_dump值。它表示有一个具有5个类型值的段,而不是5个段。
