缺少 PHP libevent 函数


我已经安装了 php-pecl-event 库，但是我看不到任何库函数：

[root@server ~]# php -r "var_dump(function_exists('event_free'));"
bool(false)
[root@server ~]# php -r "var_dump(function_exists('event_add'));"
bool(false)
[root@server ~]# php -r "var_dump(function_exists('event_buffer_free'));"
bool(false)

这些是我已经安装的软件包：

这是来自 php -i 的部分：

event

Event support => enabled
Sockets support => enabled
Debug support => disabled
Extra functionality support including HTTP, DNS, and RPC => enabled
OpenSSL support => enabled
Thread safety support => disabled
Extension version => 1.10.2
libevent2 headers version => 2.0.21-stable

有人知道缺少哪些功能吗？

答案1

PECL::事件!=PECL::libevent.
安装 libevent：

# pecl list
Installed packages, channel pecl.php.net:
=========================================
Package  Version State
libevent 0.1.0   beta
# php -r "var_dump(function_exists('event_free'));"
bool(true)
