PHP -将两个数组压缩在一起

<?php
// 定义两个数组
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);

// 使用array_merge()函数合并数组
$mergedArray1 = array_merge($array1, $array2);
print_r($mergedArray1);

// 使用+操作符合并数组
$mergedArray2 = $array1 + $array2;
print_r($mergedArray2);
?>

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);

$mergedArray = array_merge_recursive($array1, $array2);
print_r($mergedArray);
?>

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);

ksort($array1);
ksort($array2);

$mergedArray = array_merge($array1, $array2);
print_r($mergedArray);
?>
