Random fixed-length integers and various server request methods are listed

1. Randomly generate integer function (number of generated digits: $pw_length)

public function randk($pw_length)
 {
 $randpwd = '';
 for ($i=0;$i<$pw_length;$i++)
 {
 $randpwd .= chr(mt_rand(48,57));
 }
 return $randpwd;
 }


2. Request a list of various methods

"Method 1."

$url="http://www.test.com/ssl/...";

$opts = array(
 'http'=>array (
 'timeout' => 25,
 'method' => "GET",
 'header' => "Accept-language: enrn" .
 "Cookie: foo=barrn",
 )
 );
 $context = stream_context_create($opts);
 $xmlstr = file_get_contents($url,false,$context);
 $xmlstr = trim($xmlstr);

《Method 2.》

function cuel_get_contents($url, $timeout=1) {
 $curlHandle = curl_init();
 curl_setopt( $curlHandle , CURLOPT_URL, $url );
 curl_setopt( $curlHandle , CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt( $curlHandle , CURLOPT_TIMEOUT, $timeout );
 $result = curl_exec( $curlHandle );
 curl_close( $curlHandle );
 return $result;
}
$hx =cuel_get_contents('http://www.test.com');

《Method 3.》

$url="http://www.test.com/ssl/...";

echo "";
