当存储在变量中时，CURL POST / GET URL不起作用

In a nutshell...

Doesn't work

$url = "http://www.example.com/test/index.php?id=1&token=723648723";  <-- Set by previous Curl   
$ch = curl_init(); 
    curl_setopt ($ch, CURLOPT_URL, $url); 
    curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
    curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); 
    $html = curl_exec ($ch); 
    echo $html;

Works

$ch = curl_init(); 
    curl_setopt ($ch, CURLOPT_URL, "http://www.example.com/test/index.php?id=1&token=723648723"); 
    curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
    curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); 
    $html = curl_exec ($ch); 
    echo $html;

What gives? I have tried urlencode, urldecode, rawurlencode without success.

Evidently, posting the url in the browser works fine.

EDIT: I should probably add the url is obtained from another curl running right before this one. If I stored the url in a variable it works, but if I let the other curl set the variable, it doesn't.

try this:

$url = "http://www.example.com/test/index.php?id=1&token=723648723"; // < -- Set by previous Curl
$ch      = curl_init($url); // init with the given $url here

// remove curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);

$html = curl_exec($ch);
if ($html === false) // check for errors
{
    // throw new Exception('Curl error: ' . @curl_error($ch));
    echo 'Curl error: ' . @curl_error($ch);
}

@curl_close($ch); // close properly
echo $html;

UPDATE 3: clean html, spaces, new lines, replace & and force string data type ...

$url = (string) trim(strip_tags($url));
$url = str_replace('&', '&', $url);
$ch  = curl_init($url);
// etc
