一个php数据流应用的小例子，供大家学习参考。
复制代码 代码如下:
<?php
/**
php数据流应用
date：2013/2/19
*/
$count = 5;
start:
if($count < 5) echo "You can try {$count} time, ";
echo "Put Password: ";
$handle = fopen ("php://stdin","r");
$line = fgets($handle);
if(trim($line) != '123456'){
$count--;
if(!$count) goto error;
goto start;
}
goto success;
error:
echo "Please try after 1 hour! http://www.jb200.com";
goto out;
success:
echo "Logined!";
out:
?>
效果图如下所示：
