Converting Timestamps to Dates in MySQL Queries
When working with timestamps in MySQL queries, it can often be necessary to convert them into a more human-readable format, such as a date in 'yyyy-mm-dd' format. To achieve this, MySQL provides several functions that enable you to manipulate and format timestamps.
One method for converting timestamps to dates is to use the FROM_UNIXTIME() function, followed by the DATE_FORMAT() function. The FROM_UNIXTIME() function converts the timestamp into a Unix timestamp, which is the number of seconds since the epoch. The DATE_FORMAT() function then allows you to specify a format string to format the resulting timestamp.
In your case, you can use the following query to convert the user.registration field to a date in 'yyyy-mm-dd' format:
SELECT user.email, info.name, DATE_FORMAT(FROM_UNIXTIME(`user.registration`), '%Y-%m-%d') AS 'date_formatted', info.news FROM user, info WHERE user.id = info.id
This query uses the FROM_UNIXTIME() and DATE_FORMAT() functions to convert the timestamp stored in the user.registration field into the desired format. The resulting date will be stored in the date_formatted column.
By incorporating this conversion into your query, you can easily extract and format timestamp data as recognizable dates, enabling you to conveniently work with date-based information in your application or context.
The above is the detailed content of How to Convert MySQL Timestamps to 'yyyy-mm-dd' Dates?. For more information, please follow other related articles on the PHP Chinese website!

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
