给file_get_contents函数设置超时时间

$opts = array(
‘http‘=>array(
‘method‘=>"GET",
‘timeout‘=>60,
)
);

$context = stream_context_create($opts);

$html =file_get_contents(‘http://www.example.com‘, false, $context);

这样，file_get_contents获取数据时，超出60秒将会自动退出.

还可以利用file_get_contents函数实现post功能

function Post($url, $post = null)
{
$context = array();

if (is_array($post)) {
ksort($post);

$context[‘http‘] = array (
‘timeout‘=>60,
‘method‘ => ‘POST‘,
‘content‘ => http_build_query($post, ‘‘, ‘&‘),
);
}

return file_get_contents($url, false, stream_context_create($context));
}

$data = array (
‘name‘ => ‘test‘,
‘email‘ => ‘[email protected]‘,
‘submit‘ => ‘submit‘,
);

echo Post(‘http://www.example.com‘, $data);
