<body>
<form method="post" action="keli.php">
<input type="checkbox" name="orange" value="orange" >橘子<br>
<input type="checkbox" name="apple" value="apple" >苹果<br>
<input type="checkbox" name="banana[$x]" value="banana" >香蕉<br>
<input type="checkbox" name="pear[$x]" id="pear" value="pear" >梨<br>
<input type="submit" name="submit" value="提交" />
<input type="reset" name="reset" value="重置" />
</form>
</body>
<?php
echo $_POST["orange"];
echo $_POST["apple"];
echo $_POST["banana"];
echo $_POST["pear"];
?>
在没选择情况下，提交后老是出来

对,没选择的情况下,表单中的checkbox是不会提交的.
所以就提示了.
=========
你可以判断一下再输出.
if(isset($_POST["orange"])) echo $_POST["orange"];
