PHP Find Min Value From Multidimensional Array

If you are working with array of multidimensional. And you have to find the lowest/minimum/smallest value in multidimensional array by its key and value. Then you are looking for the right tutorial, 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 Value

• 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.

$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

When you use array_column () function. So this function returns a single column from a multidimensional array. By specifying the key you want to extract as the second parameter, you can extract all values associated with that key across all subarrays And when you have done this, then you have to use the min () function. Which will give you the minimum/lowest/smallest value as you can see in the above example.

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.

$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

In the example above, you initialize the minimum value with the first value in the array and then use a foreach loop to iterate over all the subarrays. And then in each sub-array compare the ‘value’ key with the current minimum value and if you find a smaller value then update the minimum value.

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.

Php smallest in array

Description

Alternative signature (not supported with named arguments):

If the first and only parameter is an array, min() returns the lowest value in that array. If at least two parameters are provided, min() returns the smallest of these values.

Note:

Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be compared to an int as though it were 0 , but multiple non-numeric string values will be compared alphanumerically. The actual value returned will be of the original type with no conversion applied.

Be careful when passing arguments of different types because min() can produce unpredictable results.

Parameters

An array containing the values.

Return Values

min() returns the parameter value considered «lowest» according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and ‘abc’ ) the first provided to the function will be returned.

Errors/Exceptions

If an empty array is passed, min() throws a ValueError .

Changelog

Version	Description
8.0.0	min() throws a ValueError on failure now; previously, false was returned and an E_WARNING error was emitted.

Examples

Example #1 Example uses of min()

echo min ( 2 , 3 , 1 , 6 , 7 ); // 1
echo min (array( 2 , 4 , 5 )); // 2

// The string ‘hello’ when compared to an int is treated as 0
// Since the two values are equal, the order they are provided determines the result
echo min ( 0 , ‘hello’ ); // 0
echo min ( ‘hello’ , 0 ); // hello

// Here we are comparing -1 < 0, so -1 is the lowest value
echo min ( ‘hello’ , — 1 ); // -1

// With multiple arrays of different lengths, min returns the shortest
$val = min (array( 2 , 2 , 2 ), array( 1 , 1 , 1 , 1 )); // array(2, 2, 2)

// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 4 < 5
$val = min (array( 2 , 4 , 8 ), array( 2 , 5 , 1 )); // array(2, 4, 8)

// If both an array and non-array are given, the array is never returned
// as comparisons treat arrays as greater than any other value
$val = min ( ‘string’ , array( 2 , 5 , 7 ), 42 ); // string

// If one argument is NULL or a boolean, it will be compared against
// other values using the rules FALSE < TRUE and NULL == FALSE regardless of the
// other types involved
// In the below examples, both -10 and 10 are treated as TRUE in the comparison
$val = min (- 10 , FALSE , 10 ); // FALSE
$val = min (- 10 , NULL , 10 ); // NULL

// 0, on the other hand, is treated as FALSE, so is «lower than» TRUE
$val = min ( 0 , TRUE ); // 0
?>

min() (and max()) on DateTime objects compares them like dates (with timezone info) and returns DateTime object.
$dt1 = new DateTime ( ‘2014-05-07 18:53’ , new DateTimeZone ( ‘Europe/Kiev’ ));
$dt2 = new DateTime ( ‘2014-05-07 16:53’ , new DateTimeZone ( ‘UTC’ ));
echo max ( $dt1 , $dt2 )-> format ( DateTime :: RFC3339 ) . PHP_EOL ; // 2014-05-07T16:53:00+00:00
echo min ( $dt1 , $dt2 )-> format ( DateTime :: RFC3339 ) . PHP_EOL ; // 2014-05-07T18:53:00+03:00
?>

It works at least 5.3.3-7+squeeze17

NEVER EVER use this function with boolean variables .
Or you’ll get something like this: min(true, 1, -2) == true;

Just because of:
min(true, 1, -2) == min(min(true,1), -2) == min(true, -2) == true;

A function that returns the lowest integer that is not 0.
/* like min(), but casts to int and ignores 0 */
function min_not_null (Array $values ) return min ( array_diff ( array_map ( ‘intval’ , $values ), array( 0 )));
>
?>

A way to bound a integer between two values is:

function bound($x, $min, $max)
return min(max($x, $min), $max);
>

So if you wanted to bound an integer between 1 and 12 for example:

PHP Get Min/Minimum Value in Array

Sometimes, you may need to find the minimum value from an array in PHP. This is a common task in programming, and fortunately, PHP provides several built-in functions to help you achieve this.

PHP gets the min or minimum or lowest value in the array. This tutorial has the purpose to explain to you several easy ways to find or get the min or minimum or lowest value from an array in PHP.

How to Find/Get Min/Minimum/Lowest value From an array

• Method 1: Using the min() function
• Method 2: Using a loop
• Method 3: Using the sort() function

Method 1: Using the min() function

The simplest and most straightforward way to find the minimum value from an array in PHP is to use the built-in min() function. This function takes an array as its argument and returns the minimum value from the array.

Syntax

min(array) or min(value1, value2, value3 … valueN)

Example 1 – Get min value in array PHP using min() function

Let’s take the first example, you will use the PHP min() function to find the smallest or minimum value in the array. Let’s see the example below:

The output of the above program is: 1

Example 2 – Find min value from an array without using PHP array functions

Let’s take the second example, in this example, you will find or get the min or minimum number in array PHP without function. Let’s see the example below:

 $val) < if($min >$val) < $min = $val; >> // get lowest or minimum value in array php using foreach print $min; ?>

The output of the above program is: 10

Example 3 – PHP get min value in array using for loop

Let’s take the third example, to find the minimum or min or smallest value in array PHP without using any function. Let’s look at the examples below:

The output of the above program is: 4

Method 2: Using a loop

Another way to find the minimum value from an array is to use a loop. This method is more complex than using the min() function, but it gives you more control over the process.

$numbers = array(5, 3, 8, 2, 9, 1); $min = $numbers[0]; for ($i = 1; $i < count($numbers); $i++) < if ($numbers[$i] < $min) < $min = $numbers[$i]; >> echo "The minimum value is: " . $min;

In this example, you initialize the $min variable to the first element of the array. You then loop through the remaining elements of the array and compare each element with the current value of $min. If the current element is smaller than $min, then update the value of $min to the current element.

Method 3: Using the sort() function

Another way to find the minimum value from an array is to sort the array in ascending order and then get the first element of the sorted array.

$numbers = array(5, 3, 8, 2, 9, 1); sort($numbers); $min = $numbers[0]; echo "The minimum value is: " . $min;

In this example, you use the sort() function to sort the array in ascending order. After sorting the array, and get the first element of the array, which is the minimum value.

Conclusion

Finding the minimum value from an array in PHP is a common task in programming. In this article, you have discussed three different ways to find the minimum value from an array in PHP. You can choose the method that suits your needs and preferences. The simplest and most straightforward method is to use the min() function. If you want more control over the process, you can use a loop. Finally, if you don’t mind modifying the original array, you can use the sort() function to find the minimum value.
