curl刮页如果失败[关闭]

Question

$url = 'http://example.com';
$site = curl_init($url);
curl_setopt($site, CURLOPT_RETURNTRANSFER, true);
$site = curl_exec($site);

if(FALSE){//DO SOMETHING}

I try to use curl scrape page, however I need to detect if url is fail.

1. question, which will be better?

   curl or file_get_contents($url)?

Answer 1

Perhaps its easier to do it without file_get_contents.

$siteContent = file_get_contents("http://example.com");

if($siteContent) {
   // do something
}

if you need more options or a post then you have to use curl. For this you have to set the option allow_url_fopen in your php.ini to On.
