PHP Find Min Value From Multidimensional Array

In this tutorial, you will learn how to find the lowest/min/smallest value in a multidimensional array.

How to Get Min Value in Multidimensional Array By Key and Value?

Here are two ways:

• Finding the minimum value in a multidimensional array by key
• Finding the minimum value in a multidimensional array by value

Finding the minimum value in a multidimensional array by key

Here, You can find the minimum value in a multidimensional array by key using the array_column() and min() function.

Here’s an example:

$data = [
  ['id' => 1, 'value' => 10],
  ['id' => 2, 'value' => 5],
  ['id' => 3, 'value' => 15]
];

$column = array_column($data, 'value');
$min_value = min($column);

echo $min_value; // Outputs 5

Finding the minimum value in a multidimensional array by value

Another way to find the minimum/smallest/lowest value in a multidimensional array, you can use foreach loop with sub-arrays.

Here’s an example:

$data = [
  ['id' => 1, 'value' => 10],
  ['id' => 2, 'value' => 5],
  ['id' => 3, 'value' => 15]
];

$min_value = $data[0]['value'];
foreach ($data as $sub_array) {
  if ($sub_array['value'] < $min_value) {
    $min_value = $sub_array['value'];
  }
}

echo $min_value; // Outputs 5

Conclusion

That’s it, In this tutorial, you have learned how to find the minimum value in a multidimensional array using array_column(), min(), foreach loop and sub_array() function.
