记录繁多的Xml foreach loop, 限制按类别和数目分列的记录
原标题:Xml foreach loop with lots of records, limit records pulled by category and number
$feed =  myfeed ;

$xml = simplexml_load_file($feed);

foreach( $xml->productinfo as $productinfo )
{
$product_category = $productinfo->category;
$product_description = $productinfo->description;

now i inserv each product categor and description into my table.
}

我把产品数据、类别和描述储存在我的数据库中。

www.un.org/Depts/DGACM/index_spanish.htm 问题是,10类的饲料有大约5,000种产品。 我无需为每个类别获得数百种产品,我只需要约50种产品。 我如何限制 for虫,例如,它通过50个微波炉 lo、停机和休息时间。

任何杀??

最佳回答

ok,如果不知会纠正,你需要这样的东西:

$feed =  myfeed ;

$xml = simplexml_load_file($feed);

foreach( $xml->productinfo as $productinfo )
{
  $product_category = $productinfo->category;
  $$product_category++;
  if($$product_category>50) continue;
  $product_description = $productinfo->description;

//now i inserv each product categor and description into my table.
}

如果你有产品——类别,请说:

$product_category= tv ;
$$product_category=$tv;

并且如果你有产品——类别的话,可以说微波:

$product_category= microwave ;
$$product_category=$microwave;
