我正在尝试使用php启动会话，但是我总是会收到此错误:

I'm trying to start a session with php, but I always get this error:

Fatal error: Call to undefined function session_start() in /www/test/test.php on line 2

我的代码(复制的格式为 php/manual/en/session.examples.basic.php ):

My Code (Copied form php/manual/en/session.examples.basic.php):

<?php session_start(); if (!isset($_SESSION['count'])) { $_SESSION['count'] = 0; } else { $_SESSION['count']++; } ?>

在我的php.ini中，我得到了 extension = session.so .此外，我在会话"部分中的设置是:

[Session] session.save_handler = files session.save_path = "/tmp" session.use_cookies = 1 ;session.cookie_secure = session.use_only_cookies = 1 session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.cookie_httponly = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 100 session.gc_maxlifetime = 1440 session.bug_compat_42 = On session.bug_compat_warn = On session.referer_check = session.entropy_length = 0 ;session.entropy_file = /dev/urandom session.entropy_file = ;session.entropy_length = 16 session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 0 session.hash_function = 0 session.hash_bits_per_character = 4 url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

推荐答案

我必须安装其他 php7-session 软件包.我想您也可以安装它:

I had to install additional php7-session package on Alpine Linux to make it work. I guess you can install it too:

opkg install php5-mod-session
