My task is call a cgi script to execute some function and process the return data. Well, here i'll mention on how to call external cgi and the process part can be settled using PHP string processing.
Let's start by example:
cgi domain location: www.xincube.com/script/handler/api.cgi
The code will strip header below and return the content of the response data.
HTTP/1.1 200 OK
Date: Sat, 06 Jun 2009 02:23:33 GMT
Server: Apache
Proxy-x-forwarded-for: 203.116.10.206
X-returncode: 0
X-returndesc: Access denied
Cache-control: no-cache
Pragma: no-cache
Connection: close
Transfer-Encoding: chunked
Content-Type: text/plain
Date: Sat, 06 Jun 2009 02:23:33 GMT
Server: Apache
Proxy-x-forwarded-for: 203.116.10.206
X-returncode: 0
X-returndesc: Access denied
Cache-control: no-cache
Pragma: no-cache
Connection: close
Transfer-Encoding: chunked
Content-Type: text/plain
We can do anything we want to get the information we need in $content.
CODE:
/* sample for calling cgi */
$host = 'www.xincube.com';
$path = '/scripts/handler/API.cgi';
$data_to_send = 'action=GetSupportedData';
PostToHost($host, $path, $data_to_send);
/* function that will call cgi */
function PostToHost($host, $path, $data_to_send) {
$header = "not yet";
$content = '';
$fp = fsockopen($host,80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)\n";
}
else {
fputs($fp, "POST $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
fputs($fp, "Content-length: ".strlen($data_to_send)."\n");
fputs($fp, "Connection: close\n\n");
fputs($fp, $data_to_send);
while(!feof($fp)) {
//echo fgets($fp, 4000);
$line = fgets( $fp, 4000 );
if( $line == "\r\n" && $header == "not yet" ) {
$header = "passed";
}
if( $header == "passed" ) {
$content .= $line;
}
}
echo $content;
fclose($fp);
}
}
