When using PHP’s mysqli extension, the mysqli_stmt::get_warnings method retrieves warnings generated during prepared statement execution. Ignoring these warnings can lead to data integrity issues, security risks, and troubleshooting difficulties. Understanding and handling these warnings ensures safer and more reliable database operations.

When using the MySQLi extension for database operations, the mysqli_stmt::get_warnings function is commonly used to retrieve warning messages returned after executing a statement. It is often used for debugging SQL queries to check if the statement was executed correctly or if there are any warnings to be aware of. However, developers may encounter the following error in some cases:

In PHP development, handling large file uploads or data transfers can be challenging. This article explores how mysqli_stmt::send_long_data provides an efficient solution for streaming large file data into MySQL databases, along with practical application scenarios and usage examples.

In PHP's MySQLi extension, mysqli_stmt::send_long_data is a function used to send large data (such as long text or large binary data) to a MySQL database. When handling large-scale data insertion, the standard bind_param() method may face data size limitations, making send_long_data() particularly useful. This article explains the basic usage of mysqli_stmt::send_long_data and important considerations when using it.

When using PHP's MySQLi extension for prepared statement operations, the mysqli_stmt::result_metadata function can return false in some cases. This article explores the common causes behind this issue and how to resolve it.
