我有一个员工类,我想从mongodb.findone()返回的数组初始化员工对象。
foreach($res as $key => $value){
echo $value; // here values printed
}
但是我需要做一些事情(如果key =' first_name'那么employee_obj-> set_first_name($ value),如果key =' last_name'那么employee_obj-> set_last_name ($ value)...)你能帮助我吗?

$employee = new Employee;
foreach($res as $key => $value){
if (property_exists($employee, $key)) {
$employee->$key = $value;
}
}
$employee->$key = $value
正在为员工动态分配$key
属性。例如:
$key = "name";
$employee->$key = "John Doe";
echo $employee->name; // John Doe
如果您想使用私有或受保护的属性执行此操作,则需要在类或实例中进行分配:
class Employee {
// ...
private $name;
// lets you assign properties by passing in an array
public function __construct($arr = array()){
if count($arr) {
foreach($arr as $key => $value){
if (property_exists($this, $key)) {
$this->$key = $value;
}
}
}
}
}
$joe = new Employee(array('name' => 'Joe'));
echo $joe->name // Joe

$e = new Employee;
foreach($res as $k => $v){
if($k == 'first_name'){
$e->set_first_name($v);
}elseif($k == 'last_name'){
$e->set_last_name($v);
}else{
$e->$k = $v;
}
}
正是这样。
