Code sample for HTTP API



<?php

$url    = 'ez4usms.com';

// open a socket to ez4usms server
$socket = fsockopen($url, 80, $errorno, $error, 30);

if( $socket == false )
{
    // something went wrong!
}
else
{
    // initialize request variables
    $username = urlencode('x');
    $password = urlencode('x');
    $from     = urlencode('x');
    $to       = urlencode('306991231111,6941236546');
    $message  = urlencode('test message');

    // construct the request path with all required parameters
    $path   = '/api/http/send.php?';
    $path  .= "username={$username}&";
    $path  .="password={$password}&";
    $path  .="from={$from}&";
    $path  .="to={$to}&";
    $path  .="message={$message}";

    // create request headers
    $req  = "GET {$path} HTTP/1.1\r\n";
    $req .= "Host: {$url}\r\n";
    $req .= "Connection: Close\r\n\r\n";

    $output = '';

    // make request
    if( fputs($socket, $req) === false )
    {
        // something went wrong with the request
        return;
    }

    // read server response
    while( !feof($socket) )
        $output .= fgets($socket, 1024);

    // manage response
    $lines  = explode("\n", $output);
    $result = end($lines);
    $parts  = explode(":", $result);


    if( $parts[0] == 'Error' )
    {
        // an error occured
        // output the error message
        echo $parts[1];
    }
    else if( $parts[0] == 'ID' )
    {
