php操作xml最快的速度學習

做分享做總結

不多嗶嗶，直接上代碼：掌握php如何通過dom對象創建xml文件，php如何讀取xml及如何讀取xml文件，獲取到讀取的xml對象就可以直接操作了

//創建一個新的DOM文檔
$dom = new DOMDocument();
//在根節點創建departs標籤
$departs = $dom->createElement("departs");
$dom->appendChild($departs);
//在departs下創建一個子標籤depart
$depart = $dom->createElement("depart");
//將depart標籤插入到departs標籤中
$departs->appendChild($depart);
//在depart標籤中添加子標籤employees
$employees = $dom->createElement("employees");
$depart->appendChild($employees);
//在employees下創建employee標籤
$employee = $dom->createElement("employee");
$employees->appendChild($employee);
//爲employee標籤添加值節點100001
$employee_num = $dom->createTextNode("100001");
$employee->appendChild($employee_num);
$file_xml = $dom->saveXML();
echo $file_xml;//輸出xml
//讀取xml
$xml_object = simplexml_load_string($file_xml);
var_dump($xml_object);
//讀取xml文件
$xml_file_object = simplexml_load_file("file_xml.xml");
var_dump($xml_file_object);
