我正在尝试将网站中的数据保存到 mysql 数据库中。我能够保存我想保存的大部分内容,但我有一个特殊的问题。我提取的链接正在保存,但我希望链接与其他属性在同一行中。下面是我的 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->getAttribute('href')”与我试图保存的其他内容分开保存。链接首先保存,然后是其余数据,使一些行为空,但我试图一次保存所有内容,即填充每一行,然后它们移动到第二行,直到 for each 语句完成。请问我该怎么做?任何帮助,将不胜感激 !!
