If you modify the code after applying the countermeasure, you can maintain security while removing backslashes without generating error logs in PHP 7.4 and later.<\/p>\n\n\n\n
To briefly explain the process: Even with Magic Quotes disabled, it executes the processing, applies stripslashes()<\/code> to the array keys and values to remove backslashes. It then recursively processes nested arrays, removes backslashes from their keys, and reassigns them with new keys. Finally, it deletes the original keys using unset()<\/code> to replicate the behavior of the original code.<\/p>\n\n\n\n
In summary, you can remove backslashes without relying on Magic Quotes.<\/p>\n","protected":false},"excerpt":{"rendered":"
