Php 如何在xml中存储数据？

我有一个php文件，其中我通过以下代码显示xml文件的数据

<?php
    $xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");
    foreach($xml->xpath('//agent') as $item) { 
    $row = simplexml_load_string($item->asXML());
    $v = $row->xpath('//id[. ="1"]');
    if($v[0]){ 
        print $item->id; 
        print $item->image; 
        print $item->name; 
        print $item->company; 
        print $item->street; 
        print $item->city;
        print $item->phone; 
    }
    else{
        echo 'No records';
    }
?>

在第一个文档中启动您的会话

<?php
    session_start();

    $xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");
    foreach($xml->xpath('//agent') as $item) { 
    $row = simplexml_load_string($item->asXML());
    $v = $row->xpath('//id[. ="1"]');
    if($v[0]){ 
        print $item->id; 
        print $item->image; 
        print $item->name; 
        print $item->company; 
        print $item->street; 
        print $item->city;
        print $item->phone; 
    }
    else{
        echo 'No records';
    }

   $name = $_session['name'][$item->name]; // dont quote ''
?>

您的会话代码无效，您可以尝试此代码

$name=$\会话['name'][$item->name]

<?php
    session_start();

    $xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");
    foreach($xml->xpath('//agent') as $item) { 
    $row = simplexml_load_string($item->asXML());
    $v = $row->xpath('//id[. ="1"]');
    if($v[0]){ 
        print $item->id; 
        print $item->image; 
        print $item->name; 
        print $item->company; 
        print $item->street; 
        print $item->city;
        print $item->phone; 
    }
    else{
        echo 'No records';
    }

   $name = $_session['name'][$item->name]; // dont quote ''
?>
