$this->"variable value" OOP PHP

本文关键字：quot OOP PHP value variable this- gt | 更新日期: 2023-09-27

我想知道这是否可能，如果是的话，我应该如何实现:

$this->id <——我有这样的东西。但为了使它更有用，我想有$this->(and here to change the values)

为例:我可能有$this->id $this->allID $this->proj_id

我怎样才能使我有$this->($myvariable here, that has a unique name in it)呢?

您可以简单地使用:

 $variable = 'id';
 if ( isset ( $this->{$variable} )  ) 
 {
    echo $this->{$variable};
 }

解决方案如下:http://www.php.net/manual/en/language.oop5.overloading.php#language.oop5.overloading.members

使用它的一个例子是:

class myClass {
    /**  Location for overloaded data.  */
    private $myProperties = array();
    public function __set($name, $value)
    {
        $this->myProperties[$name] = $value;
    }
    public function __get($name)
    {
        if (array_key_exists($name, $this->myProperties))
        {
            return $this->data[$name];
        }
    }
}

您应该查看PHP站点上的变量手册。这样，它看起来就像:

<?php
   echo ${'this->'.$yourvariable};  
?>

我更喜欢使用call_user_func并将参数传递为array。

public function dynamicGetterExample()
{
    $property = 'name'; // as an example...
    $getter = 'get'.ucfirst($property);
    $value = call_user_func(array($this,$getter));
    if (empty($value)) {
        throw new 'Exception('Required value is empty for property '.$property);
    }
    return $value;
}
