I am having trouble getting Phpstorm type hints working on arrays of objects when I test the array with is_array() before iterating over the array. Can anyone shed some light on why is_array() removes the type hinting of the objects? $test = new Test(); $testers = $test->getAll(); // Type hinting WORKS for $test foreach($testers as $test) { $test->getId(); // Type hinting works } /
我在迭代数组之前用is_array（）测试数组时遇到了Phpstorm类型提示处理对象数组的问题。 任何人都可以点亮一下为什么is_array（）删除对象的类型提示？ $test = new Test(); $testers = $test->getAll(); // Type hinting WORKS for $test foreach($testers as $test) { $test->getId(); // Type hinting works } // Type hinting does NOT work for $test if(is_array($testers)) { foreach($testers as $tes
I've been using inline @var declarations for type hinting PHP to use the prediction and reference jumping in Eclipse but what is the structure when it is a member variable like in the example below? (the below does not seem to work) /* @var $this->obj AbcObj */ $this->obj = Factory::get(...); *Assume a wide variety of object types can come out of the factory. In the class declarati
我一直在使用inline @var声明来提示PHP在Eclipse中使用预测和引用跳转，但是当它是如下例所示的成员变量时，它的结构是什么？ （以下似乎不起作用） /* @var $this->obj AbcObj */ $this->obj = Factory::get(...); *假设各种各样的对象类型可以从工厂出来。 在$this代表的类声明中，如果你已经声明$obj为一个类变量，那么在其上放一个docblock： class Foo { /** * @var AbcObj */ $obj = null; }
Is there a way to hint WebIDE that a variable has some type? I have to iterate an array of objects, and there's no auto-completion available. This helps in ZendStudio: /* @var ClassName $object */ I know there's a feature in JetBrains to declare an array of objects: /** * @return ClassName[] */ But this works only with function's return type. /* @var ClassName $object */ is
有没有办法提示WebIDE，一个变量有一些类型？ 我必须迭代一个对象数组，并且没有可用的自动完成。 这有助于ZendStudio： /* @var ClassName $object */ 我知道JetBrains中有一个用于声明一个对象数组的特性： /** * @return ClassName[] */ 但是这只适用于函数的返回类型。 /* @var ClassName $object */是一个无效的PHPDOC注释，不会在当前版本的Web IDE中解析。 使用双星号使其工作： /** @var ClassName $object *
This question already has an answer here: Reference — What does this symbol mean in PHP? 18 answers When comparing values in PHP for equality you can use either the == operator or the === operator. What's the difference between the 2? Well, it's quite simple. The == operator just checks to see if the left and right values are equal. But, the === operator (note the extra “=”) actu
这个问题在这里已经有了答案： 参考 - 这个符号在PHP中的含义是什么？ 18个答案 当比较PHP中的值时，您可以使用==运算符或===运算符。 2的区别是什么？ 那么，这很简单。 ==运算符只是检查左右值是否相等。 但是，===运算符（注意额外的“=”）实际上检查左右值是否相等，并检查它们是否具有相同的变量类型（例如它们是否都是布尔值，int等）。 http://www.programmerinterview.com/index.php/php-questions/difference
