php如何返回数组

<?php
function getArray() {
    $array = array(
        "name" => "John",
        "age" => 30,
        "city" => "New York"
    );
    return $array;
}

$result = getArray();
print_r($result);
?>

function getArray() {
    $array = array(); // 确保数组被初始化
    $array["name"] = "John";
    $array["age"] = 30;
    $array["city"] = "New York";
    return $array;
}

function getArray() {
    $array = array(
        "name" => "John", // 确保键名拼写正确
        "age" => 30,      // 确保值类型正确
        "city" => "New York"
    );
    return $array;
}

function getArray($limit = 10) {
    $array = array();
    for ($i = 0; $i < $limit; $i++) {
        $array[] = array(
            "id" => $i,
            "value" => "Item $i"
        );
    }
    return $array;
}
