Is it possible to use php to make a request to another server and get its response?

For instance user.php -> make a post request to a server http://www.exampe.com, example.com redirects to user.php and puts some post parameters as well to user.开发者_运维百科php.

I want a function in php to do that? Anyone with a solution for me?

I cannot use ajax for this.

Yes, you can achieve such functionality using cURL from PHP. Check out the examples in the PHP documentation.

For simple requests file_get_contents() will do the trick.

For more complex requirements, you van use cURL, a simple example (returning both headers and resonse body):

<?php
function curlPull($url) {
    $cPtr = curl_init();
    curl_setopt_array($cPtr, array(CURLOPT_URL => $url, CURLOPT_HEADER => true, CURLOPT_RETURNTRANSFER => true));
    return curl_exec($cPtr);
}
print_r( curlPull('http://www.example.com') );
?>

cURL allows for many more options to be tweaked, take a look at curl_setopt

I'll speculate that eventually such questions as

• Is remote access feasible withOUT cURL? and

• Are asynchronous requests possible?

will arise. While stackoverflow already abounds in explorations of these, I'll recommend http://www.ibm.com/developerworks/web/library/os-php-multitask/
