PHP xml_parse_into_struct() 函数
PHP XML Parser 函数
定义和用法
xml_parse_into_struct() 函数把 XML 数据解析到数组中。
该函数把 XML 数据解析到 2 个数组中：
- Value 数组 - 包含来自被解析的 XML 的数据
- Index 数组 - 包含指向Value 数组中值的位置的指针
如果成功，则该函数返回 1。否则返回 0。
语法
xml_parse_into_struct(parser,xml,value_arr,index_arr)
| 参数 | 描述 |
|---|---|
| parser | 必需。规定要使用的 XML 解析器。 |
| xml | 必需。规定要解析的 XML 数据。 |
| parser | 必需。规定 XML 数据的目标数组。 |
| parser | 可选。规定 index 数据的目标数组。 |
提示和注释
注释：xml_parse_into_struct() 若失败返回 0，成功则返回 1。这和 false 与 true 不同，使用例如 === 运算符时要注意。
例子
XML 文件：
<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>George</to>
<from>John</from>
<heading>Reminder</heading>
<body>Don't forget the meeting!</body>
</note>
PHP 代码：
<?php
//无效 xml 文件
$xmlfile = 'test.xml';
$xmlparser = xml_parser_create();
// 打开文件并读取数据
$fp = fopen($xmlfile, 'r');
$xmldata = fread($fp, 4096);
xml_parse_into_struct($xmlparser,$xmldata,$values);
xml_parser_free($xmlparser);
print_r($values);
?>
//无效 xml 文件
$xmlfile = 'test.xml';
$xmlparser = xml_parser_create();
// 打开文件并读取数据
$fp = fopen($xmlfile, 'r');
$xmldata = fread($fp, 4096);
xml_parse_into_struct($xmlparser,$xmldata,$values);
xml_parser_free($xmlparser);
print_r($values);
?>
