这是我关于获取div内容的问题的后续行动。第二个功能是我很难用的。我很确定我可以从另一个调用一个函数,但我不确定如何将它们放在另一个像我在这里做的那样。它显然是一个使代码工作的愚蠢尝试,因为它给了我一个错误:
Blackline Frostbyte:有货。 :$ 139.99
致命错误:无法重新声明第69行/home/rambazar/public_html/cron.php中的get_string_between()(先前在/home/rambazar/public_html/cron.php:69中声明) < / p>
正如我所看到的,代码部分正常,因为它获得了产品库存信息和价格标签,但代码停止了,我无法弄清楚 get_string_between 重新声明的位置,因为它是只叫。请帮我整理一下,谢谢!

答案 0 :(得分:1)
从get_string_between()
功能中取出getprice()
你应该很高兴:
function get_string_between($string, $start, $end)
{
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0)
return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
function getprice($itemId)
{
$data = file_get_contents("http://www.newegg.com/Product/Product.aspx?Item=".$itemId);
$pricediv = get_string_between($data, '<div class="current" id="singleFinalPrice"><span class="label">Now:', '</div');
$price = strip_tags($pricediv);
return $price;
}
