How to know whether the server has no data while reading the response of a request which is keep alive because the socket read function waits for the server to send data if we have made a request with keep alive option.
I am writing a socket program to fetch a webpage.
My request header has no connection close header so by default the connection is keep alive.
I open a connection, send the request header using socket_write and getting using a while loop to receive data
if it is a Connection Close request the everything works well.
if it is keep alive and after i have read the content the socket_read function is still waiting for data which causes the code to hand in there.
Here how do we know whether the server has completed sending the resource though it is keep alive...
i have a work around like checking the content-length response header to know how much data is received and accordingly i can stop reading
if response header has transfer-encoding as chunked then i can write more code to find the end of the response
yet without the above two workarounds how to check whether the socket_recv is still waiting for data?
Besides, i was thinking that since we are setting the read buffer length (like 1024 in this code) and the socket_recv is returning the no of bytes read and if the bytes read is less than 1024 then i can assume that the next read will not return anything and by this time i can quit the while loop.... BUT http server sends different length response so my logic will not work.
Here is my request header and the while loop in which i receive date from the server
//i have commented the connection close header so that by default it will be keep alive
$o = 'GET /search?hl=en&q='.$query.'&start='.$start.' HTTP/1.1'."\r\n";
$o.= 'Host: www.google.co.in'."\r\n";
$o.= 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0'."\r\n";
//$o.= 'Connection: close'."\r\n";
//writing $o to the socket resource//receiving the response
$bytes = socket_recv($f, $tbuf, 1024, 0x40);
if($bytes === false)
die("\r\nUnable to read headers - ".socket_strerror(socket_last_error()));
In the above code after i have received the complete html of a webpage the control is in the line where i am reading the response. Which i assume the code is still waiting for data from the server.
Hello guys, I need to use Google image with my own program. When I save the WWW.image.google.com I am not able to see the camera Icon beside the search button. I need this camera icon to click on it automatically.
can anyone tell me what is the nature of this camera icon!? is it a button or just a clickable icon!?
Thanks and regards
Thanks, I wanted to do the image searching in an automathic way so I just was not able to find the button when i saved the page. Using the advices from other friends in this webpage, I found that the camera is just an icon and behind it there is a href which addresses a java scrips code.
So thanks every one for help
I've problem with send email using php. I used this code:
$mail = new PHPMailer();
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "ssl"; // sets the prefix to the server
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = "email@example.com"; // GMAIL username
$mail->Password = "mypassword"; // GMAIL password
