How to get value of array based on matching on key - php

Question

Hi i am working on some operations where i need to get value of array from its key.
I have $attr_color variable with the value red.
So if red is in the array then it needs to be return its value.
Below is my array :
Array
(
[0] => Array
(
[label] =>
[value] =>
)
[1] => Array
(
[label] => red
[value] => 32
)
[2] => Array
(
[label] => green
[value] => 33
)
[3] => Array
(
[label] => pink
[value] => 34
)
[4] => Array
(
[label] => black
[value] => 35
)
[5] => Array
(
[label] => white
[value] => 36
)
)
I have tried below code but it returns blank :
$attr_color = "red";
//$response is my array which i have mention above.
if(in_array($attr_color,array_column($response,"label")))
{
$value = $response['value'];
echo "Value".$value;
exit;
}
Help ? where i made mistake ?

Answer 1

Use array_search, and check for false:
$index = array_search($attr_color, array_column($response,"label"));
if ($index !== false) {
echo $response[$index]['value'];
}

Answer 2

In your case it's enough to use a regular foreach loop:
$attr_color = "red";
$value = "";
foreach ($response as $item) {
if ($item['label'] == $attr_color) {
$value = $item['value'];
break; // avoids redundant iterations
}
}

Answer 3

Try this simple solution, hope this will help you out. Here we are using array_column for getting columns and indexing it with keys and values, Where keys are labels and values as value
Try this code snippet (with sample inputs)
$result=array_column($array, 'value',"label");
$result=array_filter($result);
echo $result["red"];

Answer 4

By using array_column with third parameter and array_search as
$attr_color="red";
$arr = array_filter(array_column($response, "label", 'value'));// pass thired parameter to make its key
if (array_search($attr_color, $arr)) {// use array search here
echo array_search($attr_color, $arr);
}

Answer 5

Try below code : using array match function :
$your_value = array_search($attr_color, array_column($response,"label"));
if ($index !== false) {
echo $response[$your_value]['value'];
}

Answer 6

Try:
$attr_color = "red";
//$response is my array which i have mention above.
$index = array_search($attr_color, array_column($response, 'label'));
if($index!==false){
$value = $response[$index]['value'];
echo "Value:".$value;
exit;
}
Here $index will get the index of the array with label red

Answer 7

Use array_search instead of in_array
$attr_color = "red";
if(($index = array_search($attr_color,array_column($response,"label")))!==FALSE)
{
$value = $response[$index]['value'];
echo "Value".$value;
exit;
}
