上传文件 - php://input在表单POST是否无效?
<code><form action="http://localhost/post.php" method="POST" name="aform"> <input type="file" name="myfile" id="myfile"> <input type="submit" value="提交"> </form> </code>
HTML页面中使用上面这段代码。在PHP中如此接收:
<code>$postdata = file_get_contents("php://input"); </code>
一直获取到的只有文件名,获取不到文件。想问问php://input在表单POST是否无效?是否只能走AJAX的时候才能获取到?还是说需要其他配置?
回复内容:
<code><form action="http://localhost/post.php" method="POST" name="aform"> <input type="file" name="myfile" id="myfile"> <input type="submit" value="提交"> </form> </code>

php://input
可以接受所有 body 内容。
但是遗憾的是:enctype="multipart/form-data"
时 php://input
无效
参见官方文档
php://input is not available with enctype="multipart/form-data".
大意:enctype="multipart/form-data" 的时候 php://input 是无效的。
哎。我以前也写php,但后来发现他是一个难接触到更深层次东西的语言。这不符合我的性格,所以我放弃了。php在io方面的能力。真的是。。。哎。
还是老老实实地用 file_upload 之类的函数吧。虽然很低效,但是又能怎么样呢?
祝你好运。
