Let’s talk about how to split an array into 6 parts in PHP

In PHP, we can use the array_chunk function to split an array into several small arrays of the same size of a specified length. If we want to divide an array into 6 small arrays of equal size, we can follow these steps:

Step 1: Create an array containing any number of elements. Suppose we have an array with 100 elements and we want to divide them into 6 smaller arrays of equal size.

$arr = array();
for ($i = 1; $i <= 100; $i++) {
    $arr[] = $i;
}

Step 2: Use the array_chunk function to divide the array into small arrays of equal size.

$result = array_chunk($arr, ceil(count($arr) / 6));

In this example, we use the ceil function to ensure that the last small array is randomly assigned to each small array.

Step 3: Loop through the array to check if the small arrays are separated correctly.

foreach ($result as $key => $value) {
    echo "小数组" . ($key+1) . ": ";
    print_r($value);
}

Run this code and the following will be output:

小数组1: Array([0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 [8] => 9 [9] => 10  ... [15] => 16)
小数组2: Array([0] => 17 [1] => 18 [2] => 19 [3] => 20 [4] => 21 [5] => 22 [6] => 23 [7] => 24 [8] => 25 [9] => 26  ... [15] => 32)
小数组3: Array([0] => 33 [1] => 34 [2] => 35 [3] => 36 [4] => 37 [5] => 38 [6] => 39 [7] => 40 [8] => 41 [9] => 42  ... [15] => 48)
小数组4: Array([0] => 49 [1] => 50 [2] => 51 [3] => 52 [4] => 53 [5] => 54 [6] => 55 [7] => 56 [8] => 57 [9] => 58  ... [15] => 64)
小数组5: Array([0] => 65 [1] => 66 [2] => 67 [3] => 68 [4] => 69 [5] => 70 [6] => 71 [7] => 72 [8] => 73 [9] => 74  ... [15] => 80)
小数组6: Array([0] => 81 [1] => 82 [2] => 83 [3] => 84 [4] => 85 [5] => 86 [6] => 87 [7] => 88 [8] => 89 [9] => 90  ... [9] => 100)

This code successfully divides the array into 6 small arrays of equal size, each small array contains 16 elements.

Summary

In PHP, we can use the array_chunk function to split an array into several small arrays of the same size of a specified length. In this example, we show how to split an array of 100 elements into 6 smaller arrays of equal size. The process is very simple, just use the array_chunk function and the ceil function.
