求一段防流入的代码
求一段防注入的代码
大家分享下自己的防注入的代码,复制粘贴就行.
还有addslashes和mysql_escape_string的区别就是后者必须在连接数据之后使用而已吗?
------解决方案--------------------
1、addslashes将特殊字符转义
2、preg_replace将select\or\update\alter\etc.注意还有
------解决方案--------------------
和&[这两个字符其实可以htmlspecialchars搞掉]
3、如果使用int建议最好是is_numeric(intval)一下，还有建议将整数长度截取在安全范围内。
4、防止xss攻击，一定得htmlspecialchars一下。
=================================================
php的我就常规去测试，.net我一般最留意的是int长度和
------解决方案--------------------
&这两个字符，很多人忽略这三个东西，再加上服务器配置不严格，杠杠滴往外蹦源码。

Detailed explanation of the method of converting int type to bytes in PHP
Mar 06, 2024 pm 06:18 PM
Detailed explanation of the method of converting int type to byte in PHP In PHP, we often need to convert the integer type (int) to the byte (Byte) type, such as when dealing with network data transmission, file processing, or encryption algorithms. This article will introduce in detail how to convert the int type to the byte type and provide specific code examples. 1. The relationship between int type and byte In the computer field, the basic data type int represents an integer, while byte (Byte) is a computer storage unit, usually 8-bit binary data
C++ program to convert double type variable to int type
Aug 25, 2023 pm 08:25 PM
In C++, variables of type int can only hold positive or negative integer values; they cannot hold decimal values. There are float and double values available for this purpose. The double data type was created to store decimals up to seven digits after the decimal point. Conversion of an integer to a double data type can be done automatically by the compiler (called an "implicit" conversion), or it can be explicitly requested by the programmer from the compiler (called an "explicit" conversion). In the following sections, we'll cover various conversion methods. Implicit conversions The compiler performs implicit type conversions automatically. To achieve this, two variables are required - one of floating point type and the other of integer type. When we simply assign a floating point value or variable to an integer variable, the compiler takes care of all the other things
What is the value range of int32?
Aug 11, 2023 pm 02:53 PM
The value range of int32 is from -2 to the 31st power to 2 to the 31st power minus 1, that is, -2147483648 to 2147483647. int32 is a signed integer type, which means it can represent positive numbers, negative numbers, and zero. It uses 1 bit to represent the sign bit, and the remaining 31 bits are used to represent the numerical value. Since one bit is used to represent the sign bit, the effective number of int32 bits is 31.
How many numbers does java int have?
Mar 06, 2023 pm 04:09 PM
In Java, int is a 32-bit signed data type, and its variables require 32-bit memory; the valid range of the int data type is -2147483648 to 2147483647, and all integers in this range are called integer literals. An integer literal can be assigned to an int variable, such as "int num1 = 21;".
How many bytes does int occupy?
Jan 22, 2024 pm 03:14 PM
The number of bytes occupied by the int type may vary in different programming languages and different hardware platforms. Detailed introduction: 1. In C language, the int type usually occupies 2 bytes or 4 bytes. In 32-bit systems, the int type occupies 4 bytes, while in 16-bit systems, the int type occupies 2 bytes. In a 64-bit system, the int type may occupy 8 bytes; 2. In Java, the int type usually occupies 4 bytes, while in Python, the int type has no byte limit and can be automatically adjusted, etc.
