Remote file localization with STREAM_ series functions, how to prevent card death

Remote file localization with STREAM_ series functions, how to prevent the card from dying
Or I wrote the first two days of code, has been used to collect content, today used to improve the acquisition of the content of the image and other remote file localization, sometimes will be stuck, master see how to prevent the card to die.
Code below, this code also provides two ways to achieve localization comparison, the current situation proves that this flow mode implementation efficiency is improved.

PHP Code

  
  '; $timeStart = Microtime (true); function Getmorecontent ($urls) {$timeout = 30;    $rs = Array ();    $sockets = Array ();    $userAgent = $_server[' http_user_agent ');        foreach ($urls as $id = + $url) {$tmp = Parse_url ($url);        $host = $tmp [' Host '];        $path = Isset ($tmp [' path '])? $tmp [' Path ']: '/'; Empty ($tmp [' query ']) or $path. = '? '.        $tmp [' query '];        if (Empty ($tmp [' Port ')]) {$port = $tmp [' scheme '] = = ' https '? 443:80;        } else $port = $tmp [' Port '];        $fp = Stream_socket_client ("$host: $port", $errno, $errstr, $timeout);            if ($fp) {$rs [$id] = ';            $sockets [$id] = $fp;        Fwrite ($fp, "GET $path http/1.1\r\nhost: $host \r\nuser-agent: $userAgent \r\nconnection:close\r\n\r\n");        }}//Now, wait for the results to come back in while (count ($sockets)) {$read = $sockets; This is the Magic function-explained below if (Stream_select ($read, $write = null, $e = NULL, $timeout)) {//readable sockets either has data for us, or is failed connection attempts foreach ($read as $r)                {$id = Array_search ($r, $sockets);                $data = Fread ($r, 8192);                    if (strlen ($data) = = 0) {fclose ($r);                    $tmp = Explode ("\r\n\r\n", $rs [$id], 2);                    $rs [$id] = Strpos ($tmp [0], ' $ ')? $tmp [1]: ';                Unset ($sockets [$id]);            } else $rs [$id]. = $data; }}} return $rs;} $rs = Getmorecontent ($urls), foreach ($rs as $k = = $v) {@file_put_contents ($dir. ' B_ '. BaseName ($urls [$k]), $v);} $timeEnd = Microtime (True), Echo sprintf ("Spend time:%s second (s) \ n", $timeEnd-$timeStart); >

------Solution--------------------
Since PHP does not have timers, you cannot interrupt the execution of a function that does not interrupt the interface.
So the underlying function is only suitable for the ideal condition

I still suggest you use multiple curl to do your job.

PHP code

 $urls = Array (' http://www.jxcms.com/upload/2011/ 0518/0337319304.jpg ', ' http://www.jxcms.com/upload/2011/0310/0951568835.jpg ', ' http://www.tzksgs.com/upload/       Banner1.jpg ', ' http://www.tzksgs.com/upload/banner2.jpg '); $mh = Curl_multi_init (); foreach ($urls as $i = = $url) {       $conn [$i] = Curl_init ($url);       curl_setopt ($conn [$i], curlopt_returntransfer,1); Curl_multi_add_handle ($MH, $conn [$i]);}  do {curl_multi_exec ($MH, $active); In this loop, you have the opportunity to interrupt the execution of the program.  Curl_getinfo provides various information about the connection}while ($active); foreach ($urls as $i = = $url) {$FN = basename ($url);  File_put_contents ($FN, Curl_multi_getcontent ($conn [$i]); Curl_close ($conn [$i]);}
