php - 警告 : session_start(): failed: Permission denied (13)

Question

我收到错误:

Warning: Unknown: open(/tmp/sess_beaac196b5082a77131f957bcfa35ee7, O_RDWR) failed: Permission denied (13) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

我检查了/tmp 目录，它是可写的(使用这段代码):

$filename = '/tmp';
if (is_writable($filename)) {
    echo 'The file is writable';
} else {
    echo 'The file is not writable';
}

php.ini 文件说 session.save_path 是/tmp

我是否遗漏了一些明显的东西？

编辑:我已经尝试设置一个新的 session 路径，但即使在 CHMOD 777 之后它也会告诉我:

Warning: session_start(): open(/sessions/sess_beaac196b5082a77131f957bcfa35ee7, O_RDWR) failed: No such file or directory (2) 

Answer 1

在页面开始处使用session_save_path()
