PHP set object properties dynamically
提问by Ben
I have a function, that should read array and dynamically set object properties.
我有一个函数，它应该读取数组并动态设置对象属性。
class A {
public $a;
public $b;
function set($array){
foreach ($array as $key => $value){
if ( property_exists ( $this , $key ) ){
$this->{$key} = $value;
}
}
}
}
$a = new A();
$val = Array( "a" => "this should be set to property", "b" => "and this also");
$a->set($val);
Well, obviously it doesn't work, is there a way to do this?
好吧，显然它不起作用，有没有办法做到这一点？
EDIT

It seems that nothing is wrong with this code, the question should be closed
这段代码好像没什么问题，应该关闭问题

You can using Reflection, I think.
你可以使用Reflection，我想。
<?php
function set(array $array) {
$refl = new ReflectionClass($this);
foreach ($array as $propertyToSet => $value) {
$property = $refl->getProperty($propertyToSet);
if ($property instanceof ReflectionProperty) {
$property->setValue($this, $value);
}
}
}
$a = new A();
$a->set(
array(
'a' => 'foo',
'b' => 'bar'
)
);
var_dump($a);
Outputs:
输出：
object(A)[1]
public 'a' => string 'foo' (length=3)
public 'b' => string 'bar' (length=3)

You only need to remove brackets {} and will work! -> $this->$key = $value;
您只需要删除方括号 {} 就可以了！->$this->$key = $value;
