如何設置xml屬性並將更改保存到文件？

Question

我需要使用PHP（即名稱，電話1，電話2）更改xml屬性。已更改的屬性值需要保存到代碼從其中獲取的文件中。 任何人都可以讓我走上正軌嗎？

Answer 2

你可以簡單地使用PHP：XMLWriter的這個： http://php.net/manual/de/function.xmlwriter-write-element.php

還用於讀取XML文件： http://php.net/manual/en/simplexml.examples-basic.php

它是一個遠程XML或本地在您的Web服務器上？ - 事情是你不能編輯遠程文件，我想。 最好的方法是取出舊的，在解析XML的同時更改值並再次保存。
