Hello Friends Today, through this tutorial, I will tell you how can i return minimum key value of array in php Script Code with html. There are two main ways to return the minimum key value of an array in PHP:
1. Using `min` with `array_keys`:
This method combines the `min` function and the `array_keys` function to achieve the desired result.
<?php $my_array = ["apple" => 10, "banana" => 5, "orange" => 8]; $min_value = min($my_array); // Get the minimum value $min_key = array_keys($my_array, $min_value)[0]; // Find the key of the minimum value echo "Minimum key: " . $min_key; // Output: Minimum key: banana ?>
* `min($my_array)` finds the minimum value in the array.
* `array_keys($my_array, $min_value)` returns an array of keys associated with the minimum value.
* We access the first element of the returned array using `[0]` to get the single key with the minimum value.
2. Looping and comparison:
This method iterates through the array, keeping track of the key and value with the current minimum value.
<?php
$my_array = ["apple" => 10, "banana" => 5, "orange" => 8];
$min_key = null;
$min_value = null;
foreach ($my_array as $key => $value) {
if ($min_value === null || $value < $min_value) {
$min_key = $key;
$min_value = $value;
}
}
echo "Minimum key: " . $min_key; // Output: Minimum key: banana
?>
* We initialize variables `min_key` and `min_value` to null.
* We iterate through the array using a `foreach` loop.
* Inside the loop, we check if `min_value` is null or if the current value is less than the current `min_value`.
* If the condition is true, we update both `min_key` and `min_value` with the current values.
Both methods achieve the same result. The first method is more concise and efficient, while the second method might be easier to understand for beginners due to its explicit logic.
