PHP implements separating arrays by specified number_PHP tutorial

Copy code The code is as follows:

/**
*
* Separate the array by the specified number
* @param array $array The array to be divided
* @param int $groupNum The number of groups
*/
public function splitArray($array, $groupNum){
if(empty($array)) return array();

//The total length of the array
$allLength = count($array);

//Number
$groupNum = intval($groupNum);

//Starting position
$start = 0;

//The number of elements in the divided array
$enum = (int)($allLength/$groupNum);

//Result set
$result = array();

if($enum > 0 ){

//The part of the divided group that can be divided into the number of elements in the array
$firstLength = $enum * $groupNum;
$firstArray = array();
for($i=0 ; $i<$firstLength; $i++){
                 array_push($firstArray, $array[$i]);                                                                                                                              i=0; $i<$groupNum; $i++){

                                                                                                                                                                                                                                          //Intercept elements from the specified starting position and length in the original array and put them into the new array. $firstArray, $start, $enum);

//The starting position plus the number of accumulated elements

            array_push($result[$ i], $array[$i + $firstLength]);
}
}else{
for($i=0; $i<$allLength; $i++){
