PHP数组在同一键上合并两个数组

Question

我正在尝试将以下两个数组合并为一个共享相同密钥的数组：第一个数组：array(3) {  [0]=>   array(1) {   ["Camera1"]=>   string(14) "192.168.101.71"}[1]=>array(1) {  ["Camera2"]=>  string(14) "192.168.101.72"}[2]=>array(1) {  ["Camera3"]=>  string(14) "192.168.101.74"}}第二个数组：array(3) { [0]=>  array(1) {  ["Camera1"]=>  string(2) "VT" } [1]=> array(1) {   ["Camera2"]=>   string(2) "UB" } [2]=> array(1) {  ["Camera3"]=>  string(2) "FX" }}如您所见，它们共享相同的密钥（Camera1，Camera2，Camera3等。）这是我尝试过的： $Testvar = array_merge($NewArrayCam,$IpAddressArray); foreach ($Testvar AS $Newvals){ $cam = array(); foreach($Newvals AS $K => $V){ $cam[] = array($K => $V); }

Answer 1

this would be one of the soluion:

function array_merge_custom($array1,$array2) {

    $mergeArray = [];

    $array1Keys = array_keys($array1);

    $array2Keys = array_keys($array2);

    $keys = array_merge($array1Keys,$array2Keys);

    foreach($keys as $key) {

        $mergeArray[$key] = array_merge_recursive(isset($array1[$key])?$array1[$key]:[],isset($array2[$key])?$array2[$key]:[]);

    }

    return $mergeArray;

}

$array1 = array(

    array("Camera1" => "192.168.101.71"),

    array("Camera2" => "192.168.101.72"),

    array("Camera3" => "192.168.101.74"),

);

$array2 = array(

    array("Camera1" => "VT"),

    array("Camera2" => "UB"),

    array("Camera3" => "FX")

);

echo '<pre>';

print_r(array_merge_custom($array1 , $array2));
