php开启GD库实现方法
GD库在php中默认是没有开启的，如果想让它支持图片处理功能我们需要在php.ini中把extension=php_gd2.dll 去掉前面的;就行了就行了。
在windows服务器开启php的gd库时，使用cgi之后phpinfo()得到的结果中 Configure Command 中并没有出现gd.
将php.ini文件找到extension=php_gd2.dll 去掉前面的;就行了。
另外附上如何检测是否已经安装好GD库代码！
| 代码如下 | 复制代码 |
|
if(extension_loaded('gd')) { |
|
结果显示为：你可以使用gd

如果有问题，
Configure Command 后显示的是：
1 cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8-11g=C:php-sdkoracleinstantclient11sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet=shared" "--with-mcrypt=static" "--disable-static-analyze" "--with-pgo"
可能的原因：
1.权限问题；
2.双通道是否存在问题，或者是硬件是否松动

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,
