Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (gbk_chinese_ci,COERCIB
我的php文件设置的是utf8的，数据库连接过程也都是utf8。数据库用的校对编码及字符编码是utf8_unicode_ci。但是我在执行查询句 $sql = "select * from commodity where commodity_name like '%$newstr[0]%' or Sale_Address like '%$newstr[0]%' order by id desc ";时出现了Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (gbk_chinese_ci,COERCIBLE) for operation 'like'的报错。请问谁能猜到怎么回事，该怎么解决？
------解决方案--------------------
肯能输入字符是全角或半角的问题
------解决方案--------------------
$newstr[0]里地内容改变，造成编码不统一，你可以找一种出错的情况，把$sql输出看一下

PHP Tutorial: How to Convert JSON Unicode to Chinese Characters
Mar 05, 2024 pm 06:36 PM
JSON (JavaScriptObjectNotation) is a lightweight data exchange format commonly used for data exchange between web applications. When processing JSON data, we often encounter Unicode-encoded Chinese characters (such as "u4e2du6587") and need to convert them into readable Chinese characters. In PHP, we can achieve this conversion through some simple methods. Next, we will detail how to convert JSONUnico

Jun 10, 2023 am 11:39 AM
With the development of technologies such as big data and cloud computing, databases have become one of the important cornerstones of enterprise informatization. In applications developed in Java, connecting to MySQL database has become the norm. However, in this process, we often encounter a thorny problem - inconsistent Unicode character set encoding. This will not only affect our development efficiency, but also affect the performance and stability of the application. This article will introduce how to solve this problem and make Java connect to the MySQL database more smoothly. 1. Unicode
What are the differences between unicode and ascii
Sep 06, 2023 am 11:56 AM
The differences between unicode and ascii include different encoding ranges, different storage spaces, and different compatibility. Detailed introduction: 1. The encoding range is different. The encoding range of ASCII is 0-127, which is mainly used to represent English letters. The encoding range of Unicode is much wider and can represent almost all language characters; 2. The storage space is different. ASCII usually Use 1 byte to store a character, while unicode may use 2 or more bytes to store a character; 3. Different compatibility, etc.

Sequential access Sequential access is a basic operation for processing strings in the Java language. Under this approach, each character in the input string is accessed sequentially from beginning to end, or sometimes from end to beginning. This section discusses seven technical examples of creating a 32-bit code point array from a string using sequential access methods and estimates their processing time. Example 1-1: Benchmark (no support for surrogate pairs) Listing 1 assigns a 16-bit char type value directly to a 32-bit code point value, without taking the surrogate pair into account at all: Listing 1. No support for surrogate pairs int[]toCodePointArray(Stringstr) {//Example1-1intlen=str.length();//t
