Intercepting yahoo.com.cn news [experimental only]
There are many programs for intercepting homepage news, but they are not successful.
Their working principles are nothing more than two. One is to use the back-end database interface called backend by some websites, and the other is to intercept directly based on the html code. This program uses the latter. It should be said that the fault tolerance performance is relatively good.
$open = fopen("http://www.yahoo.com.cn/index.html", "r");//Webpage address
$read = fread($open, 15000);
fclose($open);
$search = eregi("(.*)", $read, $printing );//Intercept a piece of source code, it is best to analyze the source code first
//Start extracting the remaining source code below
$printing[1] = str_replace("href="/homer/?", "href="" , $printing[1]);
$printing[1] = str_replace("href="/headlines/fullcoverage/", "href="http://www.yahoo.com.cn/headlines/fullcoverage/", $printing[1]);
$printing[1] = str_replace("", "", $printing[1 ]);
$printing[1] = str_replace("", "", $printing[1]);
$printing[1] = str_replace(" class=sbody", " ", $printing[1]);
$printing[1] = str_replace("", "", $printing[1]);
$content = $printing[1];
$content = explode("-", $content);
$headlines = sizeof($content);
for ($i = 0; $i < $headlines; $i++) {
print "News".($i+1 ).") : $content[$i]
";//The exciting moment has arrived! It shows!
}
?>
