通过特定的键的值筛选二维数组 [英] Filter 2D array by value of a particular key

问题描述

我如何过滤这个数组只有保持与项目【类别】= GT; 1 ？

  [0] =＆GT;排列
    （
        [链接] =＆GT;指数
        [图片] =＆GT;点
        【类别】= GT; 0
    ）[1] =＆GT;排列
    （
        [链接] =＆GT;测试
        [图片] =＆GT;一尘不染
        【类别】= GT; 0
    ）[2] =＆GT;排列
    （
        [链接] =＆GT; differentcat
        [图片] =＆GT; spotly
        【类别】= GT; 1
    ）
 

解决方案

使用 array_filter 。

您想这样的事情（你想保持与条目类presuming 1）

 函数categoryone（$ VAR）
{
    回报（is_array（$ VAR）及和放大器;是$ var ['类'] == 1）;
}的print_r（array_filter（$ your_arraycategoryone））;
 

How can I filter this array to only keep items with [category] => 1?

[0] => Array
    (
        [link] => index
        [image] => spot
        [category] => 0
    )

[1] => Array
    (
        [link] => test
        [image] => spotless
        [category] => 0
    )

[2] => Array
    (
        [link] => differentcat
        [image] => spotly
        [category] => 1
    )

解决方案

Use array_filter.

You want something like this (presuming you want to keep entries with category 1):

function categoryone($var)
{
    return (is_array($var) && $var['category'] == 1);
}

print_r(array_filter($your_array, "categoryone"));
