PHP基于数组实现的分页函数实例,php数组分页实例
分页功能是PHP程序设计中非常常见的功能,不同于以往的,今天本文介绍的是PHP基于数组实现的分页函数。
关于数组的分页函数,用数组进行分页的好处是可以方便的进行联合多表查询,只需要将查询的结果放在数组中就可以了以下是数组分页的函数,函数page_array用于数组的分页,函数show_array用于分页函数的操作及显示,需要配合使用。两个函数通过全局变量$countpage发生联系,此变量用于跟踪总页码数。
具体实例代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 |

希望本文所述实例对大家的PHP程序设计能起到一定的借鉴作用。
怎用PHP数组实现文件分页
你没有>,里面的39章,专门一章来讲文件上传,非常详细,最简单的部分如下:
POST 方法上传
本特性可以使用户上传文本和二进制文件。用 PHP 的认证和文件操作函数,可以完全控制允许哪些人上传以及文件上传后怎样处理。
PHP 能够接受任何来自符合 RFC-1867 标准的浏览器(包括 Netscape Navigator 3 及更高版本,打了补丁的 Microsoft Internet Explorer 3 或者更高版本)上传的文件。
相关的设置: 请参阅 php.ini 的 file_uploads,upload_max_filesize,upload_tmp_dirpost_max_size 以及 max_input_time 设置选项。
请注意 PHP 也支持 PUT 方法的文件上传,Netscape Composer 和 W3C 的 Amaya 客户端使用这种方法。请参阅对 PUT 方法的支持以获取更多信息。

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,
