How Can I Efficiently Perform Bulk Row Insertion in CodeIgniter?
Performing Bulk Row Insertion with CodeIgniter
Problem
To avoid creating extremely long queries with potentially thousands of appended values, it's advisable to explore methods for inserting multiple MySQL rows simultaneously using a single query.
Solution
Inserting multiple rows in MySQL is far more efficient than performing individual insertions. To optimize this process with CodeIgniter, take advantage of the implode() function.
Implementation
Start by creating an array to hold your SQL statements:
$sql = array();
Next, iterate through your dataset and build the SQL statements:
foreach( $data as $row ) { $sql[] = '("'.mysql_real_escape_string($row['text']).'", '.$row['category_id'].')'; }
Finally, execute the query using implode():
mysql_query('INSERT INTO table (text, category) VALUES '.implode(',', $sql));
Advantages
This approach minimizes copying by assembling the SQL statement in parts and using implode() to concatenate them efficiently. For datasets with many columns and potentially lengthy values, consider using a nested loop to dynamically build the SQL statements.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
