php mysql PHP MYSQL garbled problem, use SET NAMES utf8 to correct it

Jul 29, 2016 am 08:41 AM

Write it down first, so that you don’t have to remember it and look for it everywhere later!
When PHP operates the database, the data in the database uses UTF8 encoding. When it is read out, all that is displayed is ???????question marks and garbled characters. I found some The data is originally encoded before reading:

Copy code The code is as follows:


create table tablename
(
id int not null auto_increment,
title varchar(20) not null,
contnet varchar (300) defalut null,
primary key ('id')
)begin=MyISAM DEFAULT CHARSET =UTF8;


Execute before inserting data:

Copy code The code is as follows:


mysql_query(" SET NAMES utf8");


Then
mysql_query("insert into tablename....")
Execute before reading out the data:

Copy the code The code is as follows:


mysql_query("SET NAMES utf8");


Then mysql_query("select * from tablename")
Note: The encoding read here is output after re-encoding the original encoding content. For example, if the page where the output content is located is GBK encoding, then in When reading, the page display is also garbled, so execute mysql_query("SET NAMES gbk") before querying, and the GBK-encoded text content can be displayed normally on the page.

The above introduces the php mysql PHP MYSQL garbled problem, using SET NAMES utf8 correction, including the content of php mysql. I hope it will be helpful to friends who are interested in PHP tutorials.

How can you handle file uploads securely in PHP? How can you handle file uploads securely in PHP? Jun 19, 2025 am 01:05 AM

To safely handle file uploads in PHP, the core is to verify file types, rename files, and restrict permissions. 1. Use finfo_file() to check the real MIME type, and only specific types such as image/jpeg are allowed; 2. Use uniqid() to generate random file names and store them in non-Web root directory; 3. Limit file size through php.ini and HTML forms, and set directory permissions to 0755; 4. Use ClamAV to scan malware to enhance security. These steps effectively prevent security vulnerabilities and ensure that the file upload process is safe and reliable.

What are the differences between == (loose comparison) and === (strict comparison) in PHP? What are the differences between == (loose comparison) and === (strict comparison) in PHP? Jun 19, 2025 am 01:07 AM

In PHP, the main difference between == and == is the strictness of type checking. ==Type conversion will be performed before comparison, for example, 5=="5" returns true, and ===Request that the value and type are the same before true will be returned, for example, 5==="5" returns false. In usage scenarios, === is more secure and should be used first, and == is only used when type conversion is required.

How do I perform arithmetic operations in PHP ( , -, *, /, %)? How do I perform arithmetic operations in PHP ( , -, *, /, %)? Jun 19, 2025 pm 05:13 PM

The methods of using basic mathematical operations in PHP are as follows: 1. Addition signs support integers and floating-point numbers, and can also be used for variables. String numbers will be automatically converted but not recommended to dependencies; 2. Subtraction signs use - signs, variables are the same, and type conversion is also applicable; 3. Multiplication signs use * signs, which are suitable for numbers and similar strings; 4. Division uses / signs, which need to avoid dividing by zero, and note that the result may be floating-point numbers; 5. Taking the modulus signs can be used to judge odd and even numbers, and when processing negative numbers, the remainder signs are consistent with the dividend. The key to using these operators correctly is to ensure that the data types are clear and the boundary situation is handled well.

How can you interact with NoSQL databases (e.g., MongoDB, Redis) from PHP? How can you interact with NoSQL databases (e.g., MongoDB, Redis) from PHP? Jun 19, 2025 am 01:07 AM

Yes, PHP can interact with NoSQL databases like MongoDB and Redis through specific extensions or libraries. First, use the MongoDBPHP driver (installed through PECL or Composer) to create client instances and operate databases and collections, supporting insertion, query, aggregation and other operations; second, use the Predis library or phpredis extension to connect to Redis, perform key-value settings and acquisitions, and recommend phpredis for high-performance scenarios, while Predis is convenient for rapid deployment; both are suitable for production environments and are well-documented.
