php中file_get_contents代替使用curl示例-PHP源码

function Post($url, $post = null) {
$cOntent= http_build_query($post);
$content_length = strlen($content);
$optiOns= array(
'http' => array(
'method' => 'POST',
'header' =>"Content-type: application/x-www-form-urlencoded",
'content' => $post
)
);
return file_get_contents($url, false, stream_context_create($options));
}
