Question

我有以下代码：

class Orders{
    /**
     *
     * @var Supplier
     */
    private $suppliers; //Array of Supplier

    function loopAllSuppliers(){
        foreach($this->suppliers as $supplier){
            $supplier->/*no suggestion*/ //Can't get the method's to show here

            $this->suppliers->getSupplierName(); //methods in class Supplier show normally here
        }
    }
}

问题很简单。我只是希望能够为变量$supplier声明一个类型，就像我使用$suppliers一样。

注意：

供应商是一个具有公共方法getSupplierName（）。
我正在使用Netbeans IDE。

Answer 1

class Orders{
    /**
     *
     * @var Supplier
     */
    private $suppliers;

    function loopAllSuppliers(){
        foreach($this->suppliers as $supplier){ /* @var $supplier Supplier */
      //Must declare the type again inside the foreach as Netbeans doesn't support
      // defining variable as arrays in doc blocks, yet.
        }
    }
}

Answer 2

这应该有效：

class Orders
{
    /**
     * @var Supplier[]
     */
    private $suppliers;

    public function loopAllSuppliers()
    {
        foreach($this->suppliers as $supplier) {
        }
    }
}

Answer 3

对我来说这不起作用：

foreach ($suppliers as /* @var $supplier Supplier */ $supplier) {
    $supplier->/*should have suggestions*/
}

我的解决方案：

foreach ($suppliers as $supplier) {
    if($suppliers instancof Supplier) {
        $supplier->
    }
}

Answer 4

如果$ this-＆gt;供应商是一个数组，请尝试此操作：

function loopAllSuppliers(){
    foreach($this->suppliers as $key => $supplier){
        $supplier->/*no suggestion*/ //Can't get the method's to show here

        $this->suppliers[$key]->getSupplierName(); //should work

        $this->suppliers->getSupplierName(); //methods in class Supplier show normally here
    }
}

Answer 5

您可以通过执行以下操作来实现此目标（在netbeans中）：

    foreach ($suppliers as /* @var $supplier Supplier */ $supplier) {
        $supplier->/*should have suggestions*/
    }

Answer 6

通过PHP7和PHPStorm，我可以使用：

use path/to/Supplier; //needs the path for your class Supplier

foreach ($suppliers as /* @var $supplier Supplier */ $supplier) {
    echo $supplier->getName(); //Output each Name
}

自动完成foreach中的变量
