如何在php中将两个数组与相应的递增键合并？

I have a two arrays in php

我在php中有两个数组

$arr1 = array(1=>332, 2=>333, 3=>74, 4=>78);
$arr2 = array(1=>'heading1', 3=>'heading2');

Note:Second array keys should not be changed.

注意:不应更改第二个数组键。

这个给出了所需的输出..

$arr1 = array(1=>332, 2=>333, 3=>74, 4=>78);
$arr2 = array(1=>'heading1', 3=>'heading2');
$arr3 = array();
$total = count($arr1) + count($arr2);
for($i=1; $i<= $total; $i++)
{
    if(isset($arr2[$i])) {
        $arr3[$i] = $arr2[$i];
        continue;
    }

    $arr3[$i] = array_shift($arr1);
}

print_r($arr3);
