xml simpleXML_load_file(), simpleXML_load_string()

xml.xml文件

<?xml version='1.0'?>
<man>
    <att>
        <name>lin3615</name>
        <sex>M</sex>
        <age>26</age>
    </att>
    <att>
        <name>lin361500</name>
        <sex>mmm</sex>
        <age>20</age>
    </att>
</man>

用simpleXML_load_file()实现

<?php
$ff = 'http://localhost/test.xml';
$str = simpleXML_load_file($ff);
print_r($str);
foreach($str->att as $v) print_r($v);

function get_contents($url){
     if (ini_get("allow_url_fopen") == "1") {
                $response = file_get_contents($url);
        }else{
                $ch = curl_init();
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
                curl_setopt($ch, CURLOPT_URL, $url);
                $response =  curl_exec($ch);
                curl_close($ch);
        }

return $response;
}

用simpleXML_load_string()实现

<?php
$ff = get_contents("http://localhost/test/test.xml");
$str = simpleXML_load_string($ff);
print_r($str);
foreach($str->att as $v) print_r($v);

function get_contents($url){
     if (ini_get("allow_url_fopen") == "1") {
                $response = file_get_contents($url);
        }else{
                $ch = curl_init();
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
                curl_setopt($ch, CURLOPT_URL, $url);
                $response =  curl_exec($ch);
                curl_close($ch);
        }

return $response;
}

结果都为:

SimpleXMLElement Object
(
    [att] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [name] => lin3615
                    [sex] => M
                    [age] => 26
                )

[1] => SimpleXMLElement Object
                (
                    [name] => lin361500
                    [sex] => mmm
                    [age] => 20
                )

)

)
