提交表单 按上一页表单清空了不能正确显示怎么处理
提交表单 按下一页表单清空了不能正确显示怎么办
表单有好几个变量，提交表单后，判断各个变量与数据库的字段做比较，分页显示符合要求的数据。
但按下一页内容就变了，变成了所有数据都显示。我设的条件是表单内容为空显示所有数据的。
这样才能表单变量内容不被清空了。新手希望能用代码举个例！

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
