Compare Array key value with the given name - php

Question

Hi i am working on some array operations with loop.
I want to compare array key value with the given name.
But i am unable to get exact output.
This is my array :
Array
(
[0] => Array
(
[label] =>
[value] =>
)
[1] => Array
(
[label] => 3M
[value] => 76
)
[2] => Array
(
[label] => Test
[value] => 4
)
[3] => Array
(
[label] => Test1
[value] => 5
)
[4] => Array
(
[label] => Test2
[value] => 6
)
)
This is my varriable which i need to compare : $test_name = "Test2";
Below Code which i have tried :
$details // getting array in this varriable
if($details['label'] == $test_name)
{
return $test_name;
}
else
{
return "NotFound";
}
But every time its returns NotFound.
Not getting what exactly issue.

#Manthan Dave try with array_column and in_array() like below:
<?php
if(in_array($test_name, array_column($details, "label"))){
return $test_name;
}
else
{
return "NotFound";
}

Answer 2

$details is a multidimensional array, but you are trying to access it like a simple array.
You need too loop through it:
foreach ($details as $item) {
if($item['label'] == $test_name)
{
return $test_name;
}
else
{
return "NotFound";
}
}
I hope your array can never contain a label NotFound... :)

Answer 3

You have array inside array try with below,
if($details[4]['label'] == $test_name)
{
return $test_name;
}
else
{
return "NotFound";
}
Although foreach loop should work but if not try as,
for($i=0; $i<count($details); $i++){
if($details[$i]['label'] == $test_name)
{
return $test_name;
}
else
{
return "NotFound";
}
}

Answer 4

Traverse your array like this,
array_walk($array, function($v) use($test_name){echo $v['label'] == $test_name ? $test_name : "NotFound";});

Answer 5

Just use in_array and array_column without use of foreach loop as
if (in_array($test_name,array_column($details, 'label')))
{
return $test_name;
}
else
{
return "NotFound";
}

Answer 6

You need to check only the if condition like below because else meet at first time it will return the "notfound" then it will not execute.
$result = 'NotFound';
foreach ($details as $item) {
if($item['label'] == $test_name)
{
$result = $test_name;
}
}
return $result;
or
$result = 'NotFound';
if (in_array($test_name,array_column($details, 'label')))
{
$result = $test_name;
}
return $result;
