match mysql nbsp Stock table

抓取網頁資料如何存入mysql資料庫
請問以下的Code有沒有什麼問題呢??
主要是要抓取table內指數的資料,
表是stock(內無資料),
程序執行後stock表內仍是空白,
連接資料庫是沒問題的,
請幫忙協助修改為正確的代碼,
謝謝!!

$contents = file_get_contents('http://www.indexq.org');
preg_match_all('/

/iUs', $contents, $match);
mysql_connect("localhost", "root", "root") or die("無法連結主機");
mysql_select_db("testdb") or die("無法連結資料庫");
mysql_query("SET NAMES utf8");
$SQL = "INSERT INTO stock VALUES('{$match}')";
mysql_query($SQL);
mysql insert
------解决方案--------------------
$match应该是个数组类型,而你的 $SQL = "INSERT INTO stock VALUES('{$match}')";
把它当成了字符串类型。
鉴于你的匹配模式 s ,[\s\S]* 和 .* 表达的是一个意思,且 .* 效率会高一点
<br />preg_match_all('/<table class="marketdatatable"(.*)<\/table>/iUs', $contents, $match);<br />// ...<br />$SQL = "INSERT INTO stock VALUES('{$match[1]}')";<br />mysql_query($SQL) or die(mysql_error());
Copy after login

PHP code?1234preg_match_all('/

还有个最关键的地方忘了说了,你的stock表有哪些字段,不可能就这一个字段还把主键兼了。
你要给哪个字段写入抓取的内容?这个需要在SQL语句写清楚。

對,現在問題是在於stock內欄位該如何設定才算是正確的對應到$match上的資料,
若需要完整的表格資料,$match[1]……
我没看到你用的是 preg_match_all
这样 $match将会至少是个二维数组,即$match[1]会包含很多项。
你可以把这些用 implode连接成一个字符串
