即使 file_exists() 声明文件存在,require() 也会失败
这是我的代码:
if (file_exists('config.php')) {
require('config.php'); // This is line 38
}
以某种方式产生错误:
警告:require(config.php) [function.require]:打开流失败:第 38 行的/path/name/file.php 中没有这样的文件或目录
Warning: require(config.php) [function.require]: failed to open stream: No such file or directory in /path/name/file.php on line 38
这怎么可能?
更新:以下确实工作:
if (file_exists(getcwd(). '/config.php')) {
require(getcwd(). '/config.php');
}
推荐答案
尝试忽略包含路径:
if (file_exists('config.php')) {
require('./config.php'); // This is line 38
}
如果它有效,你就错过了.目录到包含路径中,您必须选择包含它或使用相对路径文件名
if it works you are missing . directory into the include path and you have to choose to include it or using relative path file names
您可以使用 php 配置指令更改您的 include_path(如果您可以更改 php 配置文件)或使用 get_include_path() 和 set_include_path()文件/项目库
You can change your include_path with a php configuration directive (if you can change the php config file) or resort to get_include_path() and set_include_path() on a per file/project base
ex: set_include_path('.'. PATH_SEPARATOR . get_include_path());
在你的 php 的第一行(或在一个通用的配置文件中);
ex: set_include_path('.'. PATH_SEPARATOR . get_include_path());
in your first line of php (or in a common configuration file);
