Article Introduction：PHP data filtering: effectively handle special characters in the database. When processing database operations, we often encounter some special characters or strings. These characters or strings may cause SQL statement execution to fail or the database to be injected into the attack. In order to ensure the security and reliability of data, we need to filter and process these special characters. In PHP, we can use some built-in functions or custom functions to handle these special characters. Next, I'll introduce some commonly used methods and code examples. addslas

Article Introduction：How to use PHP and GMP to implement the modular exponentiation inverse operation of large numbers. With the development of computer technology, there are more and more situations where large numbers need to be processed. In some cryptography and number theory problems, we need to perform modular inverse operations on large numbers. The modular inverse operation is to find a number such that its product with a given modulus divided by another given number gives a specific remainder. In PHP, we can use GMP (GNU Multi-Precision Arithmetic Library) to handle large number operations. GMP is a very powerful library that can efficiently handle the addition and subtraction of large integers.
