计算创建PHP类的次数 [英] Count number of times a PHP class is created

问题描述

我有一个php类，可以为其创建多个实例.我想统计一下创建该对象的次数.

I've got a php class that I create several instances for. I'd like to get a count of how many times I've created that object.

<?php
     class myObject {
         //do stuff
     }

    $object1 = new myObject;
    $object2 = new myObject;
    $object3 = new myObject;
?>

是否可以找到我已经创建了3个myObjects的方法?

Is there a way to find that I've created 3 myObjects?

推荐答案

您可以创建构造函数时递增一个>被称为.

You can create a static counter and increment it each time your constructor is called.

<?php
class BaseClass {
    public static $counter = 0;

    function __construct() {
        self::$counter++;
    }
}

new BaseClass();
new BaseClass();
new BaseClass();

echo BaseClass::$counter;
?>
