源码下载

之前写过一篇文章里面附带的有源码安装 php 的教程。

所以这里只需要下载 GMP 源码即可。

对于下载源码这件事,还是去官网(gmplib)比较好。

现在 GMP 的最新版本是 GMP 6.0.0.
然后在下载页面有三个压缩格式的文件。
我选择gmp-6.0.0a.tar.xz.
因为我的压缩工具只能解压缩这个文件。

解压缩 tar.xz 文件

对于 tar.xz 这中压缩文件我之前没有见过,不过还是有对应的压缩命令的。
我是在 CSDN 上找到的。

# -k 保持压缩文件
xz -k ***.tar.xz
tar -xzvf  ***.tar
Copy after login

安装 GMP

安装命令也是在官网安装教程页看到的。

简单说就是

./configure
make
make install
Copy after login

php 附加 gmp 源码编译

在 php 官网的 gmp 安装教程页 可以看到编译 php 的时候加上 --with-gmp 参数即可。

./configure --enable-shmop
make
make install
Copy after login

安装完之后重启一下服务器即可。

动态 添加 php 模块 扩展

编译 php 时指定需要用的模块扩展肯定可以成功,但是大多数时候我们并不想再次编译php源码。
而且我们也不记得当时编译的时候的参数了。
即使记得那些参数,编译一次也要很长时间,我们也不想等那个时间。
于是动态添加模块扩展这个需求必须要解决。

然后我在 php 的官网上随便找了一个扩展, 比如 pecl .
在目录中的最后一行可以看到 Compiling PECL extensions statically into PHP.
大概意思就是将扩展编译到php中去。

然后在第四和第五行可以看到 Compiling shared PECL extensions with the pecl command 和 Compiling shared PECL extensions with phpize.
大概意思就是 php 有两种方法动态添加模块扩展,一种是使用 pecl 命令, 另一种是使用 phpize.

接下来我们分别来看看。

pecl 命令 动态安装php模块扩展

在 pecl页面有简单的说明。

只需要下面一条命令,就会自己下载对应的模块源码,并自己安装到php中。
但是我这既然选择了源码安装,肯定不是为了显摆自己多牛X, 而是环境本身没有网络。
于是这个方法行不通了。

pecl install extname
Copy after login

phpize 动态安装php模块扩展

幸好,pecl 行不通, phpize 可以离线安装需要的扩展。
前面我们下载了源码,在编译安装前先执行 phpize ,然后正常安装就可以使用扩展了。

cd extname
phpize
./configure
make
make install
Copy after login

当然,安装完后需要配置 php.ini 文件,加入安装的模块。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
