目前对PHP流协议的定义是数据传输过程中，不同数据类型采用不同处理函数的技术规范(个人理解)这一规范比起传统文件处理函数来的更规范(诸如fget，fwrite，fopen，fclose等)
$opts =array( ‘http‘=>array( ‘method‘=>‘GET‘, ‘header‘=>‘Accept-language:zh\r\n‘, ), ); $context = stream_context_create($opts); $fp = file_get_contents(‘https://www.jianshu.com/p/04e5b9f1aecd‘,false,$context); $fw = fopen(‘wuwa.html‘,‘w‘); fwrite($fw,$fp); fclose($fw);
