can any one tell me how to use curl or file_get_contents for downloading specific data from a website and then save those specific data into my mysql database. I want to get latest additions of films from this website http://www.traileraddict.com/ and i want to save it in my database(on a daily basis; this text and html link will be shown on my website). I just need the text and html link.(highlighted in the pic)
我到处搜索过，但没有找到任何有用的教程.我有两个主要问题要问
i have searched everywhere but i didnt find any useful tutorial. i have two main questions to ask
1)如何使用cURL或file_get_contents获取特定数据.
1) How can i get specific data using cURL or file_get_contents.
2)如何将特定内容保存到我的mysql数据库表(一列中的文本，另一列中的链接)
2) How can i save the specific content to my mysql database table( text in one column and link in another column)
使用cURL:
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, 'http://www.something.com');
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
然后，您可以将元素加载到DOM对象中，并为特定数据解析dom.您也可以尝试使用搜索字符串来解析数据，但是在HTML上使用正则表达式的做法却不那么受欢迎.
Then you can load the element into a DOM Object and parse the dom for the specific data. You could also try and parse the data using search strings, but using regex on HTML is highly frowned upon.
$dom = new DOMDocument();
$dom->loadHTML( $content );
// Parse the dom for your desired content
