错误：不能将标量值用作数组

Question

 Cannot use a scalar value as an array in C:\xampp\htdocs\testing\check_array.php on line 12

见下面的程序：

<?php
    $array=array(1,2,3,3);
    $array_second=array(2,4,3,6);
    $result_array=array();

    for($start=0;$start<count($array);$start++)
    {
        $result_array[$start]=$array[$start];
        for($start_second=0;$start_second<count($array_second);$start_second++)
        {
            $result_array[$start][$start_second]=$array_second[$start_second];
        }
    }

    print_r($result_array);
?>

请告诉我我做错了什么？ 对我来说真的很有帮助

Answer 1

<?php

$array = array(1, 2, 3, 3);
$array_second = array(2, 4, 3, 6);
$result_array = array();

for ($start = 0; $start < count($array); $start++) {
// $result_array[$start] should be array, not scalar!
//    $result_array[$start] = $array[$start];
    for ($start_second = 0; $start_second < count($array_second); $start_second++) {
        // this line caused the error, cant do 0[1] = 5
        $result_array[$start][$start_second] = $array_second[$start_second];
    }
}

var_dump($result_array);
