composer is good news for phper, but sometimes, it also gives us some little troubles, such as the following error:
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
This is a very common conflict, and the impact of this conflict on composer operation is still quite severe Big, when we enable the Xdebug function, it will slow down our composer by 3-4 times. In other words: xdebug is very important for our program debugging, but it increases memory usage and process time for composer.
Composer official website provides a solution
Now I will talk about my troubleshooting ideas.
Method 1: Disable Xdebug globally through the php configuration file.
First of all, this is definitely a conflict caused by enabling Xdebug. We need to find where Xdebug is enabled.
Write a page containing the phpinfo() function and open it in the browser.
Configuration Parameters | Value |
Configuration File (php.ini) Path | /usr/local/etc/php/5.6 |
Loaded Configuration File | /usr/ local/etc/php/5.6/php.ini |
Scan this dir for additional .ini files | /usr/local/etc/php/5.6/conf.d |
Additional .ini files parsed | /usr/local/etc/php/5.6/conf.d/ext-igbinary.ini, /usr/local/etc/php/5.6/conf.d/ext-mcrypt.ini, /usr/local/etc/php /5.6/conf.d/ext-redis.ini, /usr/local/etc/php/5.6/conf.d/ext-xdebug.ini |
可见 php 调用了 php.ini 配置文件和 conf.d 目录里面的所有 ini 配置文件。
禁用 php.ini 中的 "xdebug" 模块
用分号注释掉调用语句:
;zend_extension = "/path/to/my/xdebug.so"
去除 Xdebug 相关的配置文件
如果 Xdebug 的调用不在主配置文件 php.ini 中,那么有可能在扩展配置文件夹中,比如我的环境就是如此,见上图表:
我们可以将 conf.d/ext-xdebug.ini 重命名为 ext-xdebug.bak 或者删除。这样 php 服务重启就不会调用了。当面,我们也可以参照上面的步骤,在 conf.d/ext-xdebug.ini 中将相应的 Xdebug 语句注释掉,效果相同。
方法2:通过给 composer 设置别名防止调用 Xdebug
设置别名的需要了解你自己在哪个 shell 环境下,我的机子用的是 zsh ,所以编辑 .zshrc 这个文件即可。
➜ ~ cd ➜ ~ vi .zshrc
然后根据下面两种情况选择一种方式设置你的别名,或者设置 两个别名 。
调用不含 Xdebug 模块的配置文件
对于 Xdebug 调用在 php.ini 中的情况,我们可以通过复制一份不含 Xdebug 的配置文件(xdebug-disabled-php.ini),然后建立以下别名:
alias comp='php -c /path/to/xdebug-disabled-php.ini /path/to/composer.phar'
不调用任何 php 配置文件
这种方式可以解决像我一样已经将一些扩展配置路径编译进 php 的情况:
/path/to 为你实际的文件或命令路径
OK ,现在我们执行 composer -V 试试,是否还有错误提示出现。
Good,完美解决。
以上就是解决 Composer 运行时的 Xdebug 冲突的内容,更多相关内容请关注PHP中文网(www.php.cn)!

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

The article discusses various methods for page redirection in PHP, focusing on the header() function and addressing common issues like "headers already sent" errors.

Article discusses type hinting in PHP, a feature for specifying expected data types in functions. Main issue is improving code quality and readability through type enforcement.
