Have you tried <?php echo $url ?> If it works, then short_open_tag in the php.ini is turned off. That means you will need to either turn it on or use the long open tag <?php throughout your code.

Sounds like you need to enable short_open_tag if your example doesn't work.
<?php
ini_set('short_open_tag', 'on');
$url='test.php';
?>
<html>
<body>
<form name="upload" action="<?=$url?>" method="post" >
<input type="submit" value="submit">
</form>
</body>
</html>
Alternately, write it like this:
<?php
$url='test.php';
?>
<html>
<body>
<form name="upload" action="<?php echo $url ?>" method="post" >
<input type="submit" value="submit">
</form>
</body>
</html>

删除你的单引号：
<form name="upload" action="<?=$url?>" method="post">
