php array_push()函数在clone()中的应用

for example：

在此我不再对array_push(),clone()两个函数做过多的描述，下面请看我的代码输出结果，通过结果我们再进行比对：

One:

class MyClass{

private $myArray=array();

function pushSomethingToArray($var){

array_push($this->myArray, $var);

}

function getarray(){

return $this->myArray;

}

}

$myObj=new MyClass();

$myObj->pushSomethingToArray('one');

$myObj->pushSomethingToArray('Two');

$myObjClone=clone $myObj;

$myObj->pushSomethingToArray('three');

print_r($myObj->getarray());

echo "<br>";

print_r($myObjClone->getarray());

输出结果：

Array ( [0] => one [1] => Two [2] => three )

Array ( [0] => one [1] => Two )

Two: （红色部分为改变的部分）






输出结果：

Array ( [0] => one [1] => Two )

Array ( [0] => one [1] => Two [2] => three )
