PHP7 CLI尝试两次加载xdebug - "无法加载Xdebug - 它已经加载了"

Question

将Ubuntu从14.04升级到16.04后,PHP CLI开始抱怨xdebug:

$ php -v
Cannot load Xdebug - it was already loaded
PHP 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.13-0ubuntu0.16.04.1, Copyright (c) 1999-2016, by Zend Technologies
    with Xdebug v2.4.0, Copyright (c) 2002-2016, by Derick Rethans

只有一个.ini文件:

$ ls -la /etc/php/7.0/cli/conf.d/ | grep xdebug
lrwxrwxrwx 1 root root   38 Jan 19 11:41 20-xdebug.ini -> /etc/php/7.0/mods-available/xdebug.ini

它只在以下输出中引用一次php -i:

$ php -i | grep -i configuration
Cannot load Xdebug - it was already loaded
Configuration File (php.ini) Path => /etc/php/7.0/cli
Loaded Configuration File => /etc/php/7.0/cli/php.ini
Configuration

并且在整个目录中只有一个对xdebug的引用(因此它没有被包含两次):

/etc/php/7.0$ grep -r xdebug *
mods-available/xdebug.ini:zend_extension=xdebug.so
mods-available/xdebug.ini:[xdebug]
mods-available/xdebug.ini:xdebug.remote_enable=1
mods-available/xdebug.ini:xdebug.remote_autostart=1
mods-available/xdebug.ini:xdebug.remote_port=9000
mods-available/xdebug.ini:xdebug.idekey=PHPSTORM

如果我这样做,$ phpdismod xdebug我得到以下输出,表明它仍然加载了xdebug:

$ php -v
PHP 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.13-0ubuntu0.16.04.1, Copyright (c) 1999-2016, by Zend Technologies
    with Xdebug v2.4.0, Copyright (c) 2002-2016, by Derick Rethans

完成后,它不再出现在apache配置中,如图所示phpinfo().

我该如何解决？

由于这仍然是一个问题,我发现了一些进一步的细节:

路径:

$ ls -la /usr/bin/php
lrwxrwxrwx 1 root root 21 Apr 18  2017 /usr/bin/php -> /etc/alternatives/php
$ ls -la /etc/alternatives/php
lrwxrwxrwx 1 root root 15 Feb 12 15:43 /etc/alternatives/php -> /usr/bin/php7.1

PHP:

$ php -v
Cannot load Xdebug - it was already loaded

php7.1:

有趣的是,php二进制文件与php7.1完全相同,但是当它被称为特定时,它不会显示已经加载的消息.

编辑,20181006:

我还有这个问题.下图是两个php --ini调用输出的差异.如您所见,加载的ini文件集是相同的.

它们也是符号链接的二进制文件:

ben@ben-work:~$ which php
/usr/bin/php
ben@ben-work:~$ ls -la /usr/bin/php
lrwxrwxrwx 1 root root 21 May 15 16:07 /usr/bin/php -> /etc/alternatives/php
ben@ben-work:~$ ls -la /etc/alternatives/php
lrwxrwxrwx 1 root root 15 May 30 10:13 /etc/alternatives/php -> /usr/bin/php7.1
ben@ben-work:~$ which php7.1 
/usr/bin/php7.1

Answer 1

我已经修复了这个,zend_extension=xdebug.so因为我已经在我的docker容器中启用了它docker-php-ext-enable xdebug.它可能也是为你启用的.

Answer 2

例如，您需要在 PHP 配置目录中搜索 zend_extension 声明

grep -Hnir zend_extension /etc/php/7.2/

该命令将告诉您 files:line 定义扩展名的位置，在我的情况下：

/etc/php/7.2/mods-available/xdebug.ini:2:zend_extension=/usr/lib/php/20170718/xdebug.so
/etc/php/7.2/cli/php.ini:1938:; zend_extension = /usr/lib/php/20170718/xdebug.so
/etc/php/7.2/apache2/php.ini:368:zend_extension = /usr/lib/php/20170718/xdebug.so

在这里，cli/php.ini和apache2/php.ini都是相同的配置文件，但mods-available/xdebug.ini只是另一个只有 xdebug 信息的文件。

您可以将 php.ini 中关于 xdebug 的行注释掉或移动到 xdebug.ini 并在[xdebug]部分下创建一个加入的配置。

例子：

#xdebug.ini
[xdebug]
zend_extension=/usr/lib/php/20170718/xdebug.so
xdebug.collect_params=4
xdebug.collect_vars=on
xdebug.remote_autostart=on

xdebug.var_display_max_children=128
xdebug.var_display_max_data=4086
xdebug.var_display_max_depth=10

Answer 3

zend_extension="xdebug.so"我遇到了同样的问题，并通过删除php.ini 文件中额外的代码行来解决它。

php.ini 可能适用/usr/local/etc/php/于 Mac 用户，但您可以运行以下命令来找到 php.ini 文件：

$ php -i | grep php.ini

Answer 4

在Arch Linux中，软件包xdebug生成以下配置：

/etc/php/conf.d/xdebug.ini
----------
zend_extension=xdebug.so
xdebug.remote_enable=on
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
#xdebug.max_nesting_level=300

这加载了zend_extension=xdebug.so位于相同位置的两倍/etc/php/php.ini
