Removing HTML Tags from MySQL Records
You have a database with records containing HTML tags, and you want to remove these tags efficiently without using PHP. Here's a solution using MySQL queries:
MySQL version 5.5 and above offers XML functions that can assist in this task. The following query:
SELECT ExtractValue(field, '//text()') FROM table;
extracts and returns the text content of the specified field field. By traversing the XML representation of the field using the XPath expression //text(), it effectively ignores any HTML tags.
This approach is faster than using a PHP script to remove the tags because it operates directly on the database server, avoiding data retrieval, processing, and updates done by the PHP code.
For more information, refer to MySQL's documentation on XML functions: https://dev.mysql.com/doc/refman/5.5/en/xml-functions.html.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
