使用此DOMXpath查询来从其他页面检索某些列。将DOMXpath的结果插入到MySQL中
$html = file_get_contents("http://localhost:8888/stockPrices.php");
libxml_use_internal_errors(true);
$doc = new \DOMDocument();
if($doc->loadHTML($html))
{
$result = new \DOMDocument();
$result->formatOutput = true;
$table = $result->appendChild($result->createElement("table"));
$thead = $table->appendChild($result->createElement("thead"));
$tbody = $table->appendChild($result->createElement("tbody"));
$table->setAttribute('class', 'table table-hover');
$xpath = new \DOMXPath($doc);
$newRow = $thead->appendChild($result->createElement("tr"));
foreach($xpath->query("//table[@id='kurstabell']/thead/tr/th[position()=2 or position()=3 or position()=8 or position()=9 or position()=10]") as $header)
{
$newRow->appendChild($result->createElement("th", trim($header->nodeValue)));
}
foreach($xpath->query("//table[@id='kurstabell']/tbody/tr") as $row)
{
$newRow = $tbody->appendChild($result->createElement("tr"));
foreach($xpath->query("./td[position()=2 or position()=3 or position()=8 or position()=9 or position()=10]", $row) as $cell)
{
$newRow->appendChild($result->createElement("td", trim(htmlentities($cell->nodeValue))));
}
}
echo $result->saveXML($result->documentElement);
}
这产生四列,aktier
,senaste
,högst
,lägst
和omsatt
。但我不知道如何将其插入MySQL表。即时通讯思想首先生成结果的阵列,如:
Array
(
[1] => stdClass Object
(
[aktie] => AAK AB
[senaste] => 634,50
[högst] => 638,50
[lägst] => 622,50
[omsatt] => 32 094 048
)
[2] => stdClass Object
(
[aktie] => ABB Ltd
[senaste] => 162,80
[högst] => 163,30
[lägst] => 161,90
[omsatt] => 167 481 268
)
(you get the hang of it..)
)
然后循环阵列到表中。像这样?
$sql = "INSERT INTO stock_list (`aktie`, `senaste`, `högst`, `lägst`, `omsatt`, `timestamp`) VALUES
(:aktie, :senaste, :högst, :lägst, :omsatt)";
$query = $database->prepare($sql);
foreach($data as $stock){
$query->execute(array(':aktie' => $stock->stock,
':senaste' => $stock->prevclose,
':högst' => $stock->high,
':lägst' => $stock->low,
':omsatt' => $stock->volume
));
}
我的问题:
- 我如何使用数据填充数组?
- 我如何在mysql查询中循环结果?
你正在使用哪个框架? –
'':timestamp'=> NOW()'这只是所有错误的阴影......正如$ query-> database-> prepare()'+'$ query-> execute' ...'$是什么查询“,你期待它是什么? –
@AjeetKumar我不使用框架。 – Adam
