使用curl exec返回true时退出循环

Question

-------的1.txt -----------

wrongpass1   <----- return 120
wrongpass2   <----- return 120
truepass     <----- return 1000
wrongpass3   <----- return 120

------的login.php ---------

 $file = fopen("1.txt","r");

while(! feof($file))
{
	$line = fgets($file);
	$leng = strlen($line);
	//echo $leng;
	//echo $line;
	
		$ch = curl_init();                    // initiate curl
			$url = "http://localhost/login.php"; // where you want to post data
			$pass = "pass=".$line;
			$data_string = $pass;                                                                                   

			$ch = curl_init('http://localhost/login.php');                                                                      
			curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
			curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

				$data_len = strlen ($result);

总是返回120,120,120,120。 如何修复它以显示120,120,1000,120？

如果删除wrongpass3，它将返回120,120,1000。 但如果真正的通过是其中之一，它只返回120,120,120,120。

还有其他方法可以确定发回的字节数。例如：

$file = fopen("1.txt","r");

while(! feof($file)) {
    $line = fgets($file);
    $leng = strlen($line);
    $ch = curl_init();
    $url = "http://localhost/login.php";
    $pass = "pass=".$line;
    $data_string = $pass;
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
    if($infp['size_download'] > 120){
        echo "{$infp['size_download']}<br />";
        echo $line;
        break;
    }
}
fclose($file);
