Yet another php example for using http stream

[AutomGuy]

Hi Christian,
i have made another php example for http stream to distribute sensor datas,

/*
Short example of an TCP client written in PHP for rtl_433.

You need to have `php_cli` installed.

To run this as service use these systemd service files for
ubuntu, lubuntu, xubuntu, debian, ubuntu core and so on.

## Service file to start the rtl_433 process

[Unit]
Description=rtl433 tcp service
After=network.target
[Service]
Restart=always
RestartSec=5
RemainAfterExit=no
User=root
ExecStart=/bin/sh -c "/usr/bin/rtl_433 -f 433920000 -f 433920000 -H 120 -F http:127.0.0.1:8433"

[Install]
WantedBy=multi-user.target

## Service file to start the php udp server

[Unit]
Description=http 433 tcp service
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=root
ExecStart=/usr/bin/php /home/user/rtl_433/examples/rtl_433_custom_http_stream.php

[Install]
WantedBy=multi-user.target

#!/usr/bin/php
<?php

// Function to check $needle 
// with given $haystack 
function startsWith ($haystack, $needle) 
{ 
    $len = strlen($needle); 
    return (substr($haystack, 0, $len) === $needle); 
} 

// Function to check the $haystack is ends  
// with given $needle or not 
function endsWith($haystack, $needle) 
{ 
    $len = strlen($needle); 
    if ($len == 0) { 
        return true; 
    } 
    return (substr($haystack, -$len) === $needle); 
}

//Function to check $haystack if
//$needle in $haystack
function str__contains($haystack,$needle)
{ 
  $ret = false;
  if (strpos($haystack, $needle) !== false) 
  { 
      $ret = true; 
  } 
  return $ret;
} 


//main
$adr  = "127.0.0.1";
$port = "8433";
$url  = $sdr . ":" . $port . "/stream";

$fp = stream_socket_client("tcp://" . $url , $errno, $errstr, 70);
if (!$fp) {
    //optional error output
    //echo "$errstr ($errno)<br />\n";
} else {
    fwrite($fp, "GET / HTTP/1.0\r\nHost: " . $adr . "\r\nAccept: */*\r\n\r\n");
    while (!feof($fp)) {
        $line = fgets($fp, 1024);
        //time is available in all received records, that is the filter word 
        //for sensor data
        if(str__contains($line,"time"))
        {
         //raw output of json
         print_r($line);
          /*
          do something with content of $line
          for example decode $line into a array
          $arr = json_decode($line,true);
  
          do something with that array and
          puted into a file as json  
          file_put_contents('test.json', json_encode($arr, JSON_PRETTY_PRINT);
          */
        }
    }
    fclose($fp);
}
?>

i think it is quite simple example in a other programing language. Could you upload this into the example folder?

Best Regards
