也许你可以解析页面的元标记?
葡萄藤页面来源:
<meta property="twitter:card" content="player">
<meta property="twitter:title" content="Jethro Ames's post on Vine">
<meta property="twitter:description" content="SquareVine 1 #howto #favthings #loop">
使用file_get_contents和preg_match:
从php获取描述<?php
$url = "https://vine.co/v/bjHh0zHdgZT";
$data = file_get_contents($url);
preg_match('~<\s*meta\s+property="(twitter:description)"\s+content="([^"]*)~i', $data, $matches);
print_r($matches);
if ( isset($matches[2]) ) {
$description = $matches[2];
}
?>
输出:
Array
(
[0] => <meta property="twitter:description" content="SquareVine 1 #howto #favthings #loop
[1] => twitter:description
[2] => SquareVine 1 #howto #favthings #loop
)
您的描述是$ matches [2]。小心控制这个内容(html实体,sql转义等)
