Question

如何按顺序组合顺序数组和关联数组：

示例：

$sequentialArray = [123, 'Jonh'];
$associativeArray = ['ID' => '321', 'name' => 'Paul', 'lastName' => 'Wood'];

mergeArray($sequentialArray, $associativeArray);

返回：

Array
(
    [ID] => 123
    [name] => Jonh
    [lastName] => Wood
)

Answer 1

考虑一下：

<?php
header('Content-Type: text/plain; charset=utf-8');

$sequentialArray  = [ 123, 'Jonh'];
$associativeArray = ['ID' => '321', 'name' => 'Paul', 'lastName' => 'Wood'];

$keys = array_slice(
    array_keys($associativeArray),
    0,
    count($sequentialArray)
);

print_r(
    array_merge(
        $associativeArray,
        array_combine($keys, $sequentialArray)
    )
);
?>

<强>输出：

Array
(
    [ID] => 123
    [name] => Jonh
    [lastName] => Wood
)

这是功能：

<?php
header('Content-Type: text/plain; charset=utf-8');

$sequentialArray  = [ 123, 'Jonh'];
$associativeArray = ['ID' => '321', 'name' => 'Paul', 'lastName' => 'Wood'];

function mergeArray($assoc, $seq){
    $keys = array_slice(array_keys($assoc), 0, count($seq));

    return array_merge($assoc, array_combine($keys, $seq));
}

print_r(mergeArray($associativeArray, $sequentialArray));
?>

Answer 2

试试这个

$sequentialArray = [123, 'Jonh'];
$associativeArray = ['ID' => '321', 'name' => 'Paul', 'lastName' => 'Wood'];
$newArr = array();
$i = 0;
foreach($associativeArray as $key=>$val){
    if(isset($sequentialArray[$i])){
        $newArr[$key] = $sequentialArray[$i];
    }else{
        $newArr[$key] = $val;
    }
    $i++;
 }

<强>输出：

 Array
 (
    [ID] => 123
    [name] => Jonh
    [lastName] => Wood
 )

 print_r($newArr);
