如何检查PHP数组中的任何键中是否存在值 [英] How to check if a value exists in any key in PHP array
问题描述
Hello All，
我有一个大约20个关键项的数组，每个键有13个值。如果存在，我需要在所有键中搜索特定值，如果存在，我需要该值的键索引。
例如我有
数组
（
[0] =>数组
（
[0] => abc
[1] => def
[2] => ghi
[3] => jkl
[4] => mno
[5] => dfdsg
[6] => PIC
[7] => pqr
[8] => 1543
[9] => stu
[10] => wx
[11] => yz
[12] =>我们
[13] => fewfw
）
）
从这里我需要搜索def，我需要关键索引def 。
请帮忙。
我尝试过的事情：
$ ids = array_column（$ array，'1'）;
if（isset（$ ids [$ array [$ ind] [1]]））
{
}
Hello All,
I have an array of around 20 key items with 13 value in each key. I need to search specific value in all the keys if exists and if it exists I need the key index of that value.
For e.g. I have
Array
(
[0] => Array
(
[0] => abc
[1] => def
[2] => ghi
[3] => jkl
[4] => mno
[5] => dfdsg
[6] => PIC
[7] => pqr
[8] => 1543
[9] => stu
[10] => wx
[11] => yz
[12] => we
[13] => fewfw
)
)
From this I need to search for "def" and I need the key index of "def".
Please help .
What I have tried:
$ids = array_column($array, '1');
if(isset($ids[$array[$ind][1]]))
{
}
推荐答案
ids = array_column（
ids = array_column(
array，'1'）;
if（isset（
array, '1');
if(isset(
ids
