用file_get_contents获取字符串问题
我有两个页面
a.php

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php echo '1';?>
Copy after login

b.php
PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$opts = array('http'=>array('method'=>"GET",'timeout'=>3,));$context = stream_context_create($opts);$open =file_get_contents("http://127.0.0.1/a.php", false, $context);if($open=='1'){echo '2'}
Copy after login


为什么$open=='1' 为false?

a.php改怎么写才能让$open=='1' 为true?

------解决方案--------------------
刚代码没出来,嘿嘿,现在看到你代码了。

a.php修改成

1

即可.

file_get_contents() 函数把整个文件读入一个字符串中。注意把整个文件读入一个字符串


------解决方案--------------------
请去确认 allow_url_fopen = On
------解决方案--------------------
楼主,我测试是没有问题的啊,$open=='1'是成立的。
------解决方案--------------------
亲测,没有问题,可能是你fopen没有打开
