PHP stdClass()用法及代碼示例

要將數組轉換為對象，請使用 stdClass()。 stdClass() 是一個空類，用於將其他類型轉換為對象。如果將對象轉換為對象，則不會對其進行修改。但是，如果對象類型被轉換/type-casted，則會創建 stdClass 的實例，如果它不是 NULL。如果為 NULL，則新實例將為空。

範例1：它使用 stdClass 將數組轉換為對象。

PHP


<?php
// Function to convert array into
// stdClass object
function ToObject($Array) {
     
    // Create new stdClass object
    $object = new stdClass();
     
    // Use loop to convert array into
    // stdClass object
    foreach ($Array as $key => $value) {
        if (is_array($value)) {
            $value = ToObject($value);
        }
        $object->$key = $value;
    }
    return $object;
}
// Declare an array and initialize it
$Original = array (
    '1' => array(
        'sNo' => '1',
        'Age' => '20',
        'name' => 'A'
    ),
    '2' => array(
        'sNo' => '2',
        'Age' => '21',
        'name' => 'B'
    ),
    '3' => array(
        'sNo' => '3',
        'Age' => '22',
        'name' => 'C'
    ),
    '4' => array(
        'sNo' => '4',
        'Age' => '23',
        'name' => 'D'
    ),
    '5' => array(
        'sNo' => '5',
        'Age' => '24',
        'name' => 'E'
    )
);
// Display the original array
print_r($Original);
// Function call
$convertedObj = ToObject($Original);
// Display the stdClass object
print_r($convertedObj);
?>

輸出：

Array
(
    [1] => Array
        (
            [sNo] => 1
            [Age] => 20
            [name] => A
        )

    [2] => Array
        (
            [sNo] => 2
            [Age] => 21
            [name] => B
        )

    [3] => Array
        (
            [sNo] => 3
            [Age] => 22
            [name] => C
        )

    [4] => Array
        (
            [sNo] => 4
            [Age] => 23
            [name] => D
        )

    [5] => Array
        (
            [sNo] => 5
            [Age] => 24
            [name] => E
        )

)
stdClass Object
(
    [1] => stdClass Object
        (
            [sNo] => 1
            [Age] => 20
            [name] => A
        )

    [2] => stdClass Object
        (
            [sNo] => 2
            [Age] => 21
            [name] => B
        )

    [3] => stdClass Object
        (
            [sNo] => 3
            [Age] => 22
            [name] => C
        )

    [4] => stdClass Object
        (
            [sNo] => 4
            [Age] => 23
            [name] => D
        )

    [5] => stdClass Object
        (
            [sNo] => 5
            [Age] => 24
            [name] => E
        )

)

範例2：它使用 stdClass 將數組轉換為對象。

PHP


<?php
// Function to convert array into
// stdClass object
function ToObject($Array) {
     
    // Create new stdClass object
    $object = new stdClass();
     
    // Use loop to convert array into object
    foreach ($Array as $key => $value) {
        if (is_array($value)) {
            $value = ToObject($value);
        }
        $object->$key = $value;
    }
    return $object;
}
// Declare an array
$Original = array(1, 2, 3, 4, 5, 6);
// Display the array element
print_r($Original);
// Function call to convert object
$convertedObj = ToObject($Original);
// Display the stdClass object
print_r($convertedObj);
?>

輸出：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
)
stdClass Object
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
)
