What are the differences between unsigned integers and signed integers?
Article Introduction:The difference between unsigned integer and signed integer: 1. Numeric range; 2. Symbol processing method. Detailed introduction: 1. Numerical range. The value range of unsigned integer type is non-negative, while the value range of signed integer type includes positive numbers, negative numbers and zero. This is because in unsigned integer type, all bits are Used to represent numerical values, and in signed integers, the highest bit is used to represent symbols; 2. Sign processing method, signed integers use two's complement to represent numerical values, including a sign bit, which is used to represent numerical values. The positive and negative bits are used to represent the value itself, etc.

What does unsigned integer mean?
Article Introduction:Unsigned integer is a data type in computer programming used to represent non-negative integers. It has no sign bit, all bits are used to represent numeric values. The value range of unsigned integers is always non-negative, and its maximum value depends on the specific programming language and system. Using unsigned integers can easily handle some non-negative integer problems and avoid overflow problems. Compared with signed integers, unsigned integers behave differently when dealing with negative numbers, so the choice of use should be considered based on specific needs.

What is a signed integer?
Article Introduction:A signed integer is a data type used in computer programming to represent integers. Its value range includes positive numbers, negative numbers, and zero, because in signed integers, the highest bit is used as the sign bit to represent the sign of the value. It uses two's complement form to represent the sign of the value, with the highest bit used as the sign bit. The value range of signed integer types includes positive numbers, negative numbers, and zero, and is suitable for processing values that may have positive or negative changes. When using signed integers, you need to pay attention to the boundaries and range of values to avoid overflow or underflow.

How to convert string to integer array in php
Article Introduction:In PHP, we often need to convert strings into integer arrays for further processing of data. Below we will introduce several methods to convert a string into an array of integers. Method 1: Use the explode() function. The explode() function can split a string into an array according to the specified delimiter. By using this function and type conversion, we can convert a comma separated string into an array of integers. For example, we have the following string:```$str = "1,2,3,4,5";```Then
