Question

我正在尝试将数据从网站保存到mysql数据库中。我能够保存我想保存的大部分内容，但我有一个特别的问题。我提取的链接正在保存，但我希望链接与其他属性位于同一行.Below是我的CURL和mysql查询，用于提取信息并将其保存到数据库中。

$target_url = "http://www.ucc.ie/modules/descriptions/BM.html";
$codeS = "BM";
$html = file_get_contents("http://www.ucc.ie/modules/descriptions/BM.html"); 
@$doc = new DomDocument(); 
@$doc->loadHtml($html); 
//discard white space   
@$doc->preserveWhiteSpace = false; 
$xpath = new DomXPath($doc);

//Read through dd tags
$options = $doc->getElementsByTagName('dd');

//Go into dd tags and look for all the links with class modnav 
$links = $xpath->query('//dd //a[@class = "modnav"]'); 

//Loop through and display the results for links
foreach($links as $link){    
echo $link->getAttribute('href'), '<br><br>';
}   

foreach ($options as $option) { 

    $option->nodeValue;
    echo "Node Value (Module name/title)= $option->nodeValue <br /><br /> <br />"; 

      // save both for each results into database
$query3 = sprintf("INSERT INTO all_modulenames(code,module_name,description_link,gathered_from) 
     VALUES ('%s','%s','%s','%s')",
     mysql_real_escape_string ($codeS),
     mysql_real_escape_string($option->nodeValue),
     mysql_real_escape_string($link->getAttribute('href')),
     mysql_real_escape_string($target_url));
     mysql_query($query3) or die(mysql_error()."<br />".$query3); 

    } 
    echo "<br /> <br /> <br />";


Here is the table
-- ----------------------------
-- Table structure for `all_modulenames`
-- ----------------------------
DROP TABLE IF EXISTS `all_modulenames`;
CREATE TABLE `all_modulenames_copy` (
`code` varchar(255) NOT NULL,
`module_name` varchar(255) NOT NULL,
`description_link` varchar(255) NOT NULL,
`gathered_from` varchar(255) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

-- ----------------------------
-- Records of all_modulenames
-- ----------------------------

所以问题是“$ link-＆gt; getAttribute（'href'）”与我试图保存的其他内容分开保存。首先保存链接，然后是其余数据，然后将一些行留空但我试图一次性保存所有内容，即填充每一行，然后移动到第二行，直到每个语句完成。我怎么能这样做？任何帮助将不胜感激!!

未经测试（因此需要调试）但我会接近这样的事情：

...etc
@$doc->preserveWhiteSpace = false;  

//Read through dd tags 
$options = $doc->getElementsByTagName('dd'); 

foreach ($options as $option) {  

    // Get the links and find the one with the right class
    $href = '';
    $links = $option->getElementsByTagName('a');
    foreach ($link as $link) {
        if ($link->hasAttribute('class') && $link->hasAttribute('href')) {
            $aClasses = explode(' ', $link->getAttribute('class'));
            if (in_array('modnav', $aClasses)) {
                  $href=$link->getAttribute('href');
            }
        }
    }

    Insert in to SQL etc, $href is the link text belonging to the dd ...

链接与mysql数据库中的其他数据分开保存
