我创建了一个脚本,它读取一个 XML 文件并将其添加到数据库中。我为此使用 XML Reader。问题是我的 XML 中包含 500,000 个产品。这会导致我的页面超时。我有办法做到这一点吗?
我的代码如下:
$z = new XMLReader;
$z->open('files/NAGardnersEBook.xml');
$doc = new DOMDocument;
# move to the first node
while ($z->read() && $z->name !== 'EBook');
# now that we're at the right depth, hop to the next <product/> until the end of the tree
while ($z->name === 'EBook')
{
$node = simplexml_import_dom($doc->importNode($z->expand(), true));
# Get the value of each node
$title = mysql_real_escape_string($node->Title);
$Subtitle = mysql_real_escape_string($node->SubTitle);
$ShortDescription = mysql_real_escape_string($node->ShortDescription);
$Publisher = mysql_real_escape_string($node->Publisher);
$Imprint = mysql_real_escape_string($node->Imprint);
# Get attributes
$isbn = $z->getAttribute('EAN');
$contributor = $node->Contributors;
$author = $contributor[0]->Contributor;
$author = mysql_real_escape_string($author);
$BicSubjects = $node->BicSubjects;
$Bic = $BicSubjects[0]->Bic;
$bicCode = $Bic[0]['Code'];
$formats = $node->Formats;
$type = $formats[0]->Format;
$price = $type[0]['Price'];
$ExclusiveRights = $type[0]['ExclusiveRights'];
$NotForSale = $type[0]['NotForSale'];
$arr[] = "UPDATE onix_d2c_data SET is_gardner='Yes', TitleText = '".$title."', Subtitle = '".$Subtitle."', PersonName='".$author."', ImprintName = '".$Imprint."', PublisherName = '".$Publisher."', Text = '".$ShortDescription."', BICMainSubject = '".$bicCode."', ExcludedTerritory='".$NotForSale."', RightsCountry='".$ExclusiveRights."', PriceAmount='".$price."', custom_category= 'Uncategorised', drm_type='adobe_drm' WHERE id='".$isbn."' ";
# go to next <product />
$z->next('EBook');
$isbns[] = $isbn;
}
foreach($isbns as $isbn){
$sql = "SELECT * FROM onix_d2c_data WHERE id='".$isbn."'";
$query = mysql_query($sql);
$count = mysql_num_rows($query);
if($count >0){
} else{
$sql = "INSERT INTO onix_d2c_data (id) VALUES ('".$isbn."')";
$query = mysql_query($sql);
}
}
foreach($arr as $sql){
mysql_query($sql);
}
谢谢,
