Question

我有一个带有stdClass对象的数组，如下所示。我如何计算Interviewee_Name下的数量？

尝试计数，因为我会做一个数组，但得到一个错误，我不能因为stdClass对象，然后不确定如何从那里继续

Array
(
    [0] => stdClass Object
        (
            [Interviewee_Name] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => rn_Interviewee_Name_DIR_27
                            [value] => Janusz Jasinski
                        )

                )

        )

Answer 1

这将获得from lib import window, widgets from PyQt5.QtCore import pyqtSlot class FileUploader: def __init__ (self, windowObj): self.progressBar = None self.logViewer = None self.closeButton = None self.filePercent = 100 self.totalPercent = 0 self.fileSelectDialog = None self.__createWidgets (windowObj) return def __createWidgets (self, windowObj): vboxObj = widgets.VBox () hboxObj = widgets.HBox () self.progressBar = widgets.ProgressBar (parent=windowObj) self.logViewer = widgets.TextEdit (parent=windowObj) self.closeButton = widgets.PushButton ('&Close', parent=windowObj) hboxObj.addWidget (self.progressBar) hboxObj.addWidget (self.closeButton) vboxObj.insertLayout (0, hboxObj) vboxObj.addWidget (self.logViewer) windowObj.setLayout (vboxObj) (self.closeButton).clicked.connect (self.test) return def acceptInputFiles (self, winTitle, fileFilters, windowObj): (self.progressBar).setRange (0,100) (self.progressBar).setValue (0) self.fileSelectDialog = window.FileDialog (title=winTitle, filter=fileFilters, parent=windowObj) selectedFiles = (self.fileSelectDialog).getSelectedFiles () if len(selectedFiles) == 0: (self.logViewer).append ('No Files to process') return selectedFiles @pyqtSlot() def test (self): print ('clicked')下的元素数量，但它会计算所有元素，而不仅仅是对象。

Interviewee_Name

但是，如果您真的只想在count($arr[0]->Interviewee_Name)中获取对象，则需要array_filter数组才能获取对象，然后算新阵列：

Interviewee_Name

从数组中获取元素的语法类似于count(array_filter($arr[0]->Interviewee_Name, function ($el) { return (gettype($el) == 'object'); }));，但在这种情况下，$arr['index']是对象的属性，因此您需要使用对象语法：Interviewee_Name < / p>

Answer 2

$array = json_decode(json_encode($formData), True);

我在计算之前添加了它，然后才有效！
