Question

我正在编写从wbsite读取xml。

$jtype = $job_type == 1 ? 'fulltime' : $job_type == 2 ? 'parttime' : $job_type == 3 ? 'contract':'';
    $xml ="http://api.indeed.com/ads/apisearch?";
    $xml .="publisher=9628233567417007";
    $xml .="&q=".$q; //Query. By default terms are ANDed. To see what is possible, use our advanced search page to perform a search and then check the url for the q value.
    $xml .="&l=".$location; //Location. Use a postal code or a "city, state/province/region" combination.
    $xml .="&sort="; //Sort by relevance or date. Default is relevance.
    $xml .="&radius=30"; //Distance from search location ("as the crow flies"). Default is 25.
    $xml .="&st=employer"; //Site type. To show only jobs from job boards use 'jobsite'. For jobs from direct employer websites use 'employer'.
    $xml .="&jt=".$jtype ; //Job type. Allowed values: "fulltime", "parttime", "contract", "internship", "temporary".
    $xml .="&start=0"; //Start results at this result number, beginning with 0. Default is 0.
    $xml .="&limit=10"; //Maximum number of results returned per query. Default is 10
    $xml .="&fromage=".$within; //Number of days back to search.
    $xml .="&filter=1"; //Filter duplicate results. 0 turns off duplicate job filtering. Default is 1.
    $xml .="&latlong=1"; //If latlong=1, returns latitude and longitude information for each job result. Default is 0.
    $xml .="&co=GB";//arch within country specified. Default is us. See below for a complete list of supported countries. 
    $xml .="&v=2";

    $xmlData = new SimpleXMLElement( $xml, null, true);
    $xmls = $xmlData->xpath('results/result');

    $jIndeed = array();
    $iIndeed=1;
    if( !empty($xmls) )
    {
        foreach ( $xmls as $xml )
        {
            $created_at = strftime( dateFormat ,strtotime((string)$xml->date));
            $jIndeed[$iIndeed]['job_id']            = (string)$xml->jobkey;
            $jIndeed[$iIndeed]['jobTitle']          = cleanText( (string)$xml->jobtitle );
            $jIndeed[$iIndeed]['var_name']          = seoUrl( (string)$xml->jobtitle);
            $jIndeed[$iIndeed]['jobDescription']    = (string)$xml->snippet;
            $jIndeed[$iIndeed]['created_at']        = $created_at;
            $jIndeed[$iIndeed]['job_type']          = (string)$xml->typeName;
            $jIndeed[$iIndeed]['companyName']       = (string)$xml->company;
            $jIndeed[$iIndeed]['location']          = (string)$xml->formattedLocation;
            $iIndeed++;
        }
        $smarty->assign('searchIndeed', $jIndeed);
    }

当我在本地计算机上运行时，它工作正常，但当我上传到我的网站时，我收到错误500“页面无法显示”

我已将memery更改为20MB并将帖子更改为1000但仍然失败。我认为我的主机有限制，当我在php中设置仍然失败时，它没有任何差异，

是否有任何xml类我可以用来处理这个网站xml。

更新

放入此ini_set('display_errors', E_ALL);

之后

Answer 1

对于安全季节，php在默认设置中禁用fopen url。您最好根据php curl lib获取xml文件内容并将其保存到本地文件。

然后使用new SimpleXMLElement ($localxml)。

示例代码：

$xml = "http://....";

$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $xml);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

// grab URL and pass it to the browser
$xmlcontent = curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);

file_put_contents('/tmp/xmlfile', $xmlcontent);
$xmlelement = new SimpleXMLElement( $xml, null, true);
.....

Answer 2

试试这个

$xmlData  = simple_xml_load_file(file_get_contents($xml));
print_r($xmlData);

而不是

 $xmlData = new SimpleXMLElement( $xml, null, true);

PHP处理XML数据
