PHP dynamically generates PHP code: special character processing and security practices

31 Aug 2025

This article discusses how PHP correctly handles the string parsing problem of special characters such as tags and $variable when generating PHP files. The article first recommends using JSON or database to store data to improve security rather than directly generating PHP code. Then, the methods such as backslash escape, switching quotation mark types and string splicing are explained in detail to avoid PHP string interpretation, ensuring that the dynamically generated PHP code is complete and executable. Finally, the importance of safely storing sensitive data is emphasized.

This article aims to clarify the correct use of the Python verification-email library, especially when processing email address verification results. Many developers may mistakenly think that the library will throw a VerifyEmailError exception when verification fails, but in reality, it indicates the verification result by returning a boolean value True or False. Understanding this design helps avoid AttributeError and enables the verification logic of email addresses in a concise and effective way.
