mysqlfetchrow

mysqlfetchrow is a function in older versions of the MySQL C API used to retrieve a single row of data from a result set obtained from a MySQL query. When a query is executed, it returns a result resource, and mysqlfetchrow is called repeatedly on this resource to iterate through the rows. Each call to mysqlfetchrow fetches the next available row. The function returns a null pointer when there are no more rows to retrieve or if an error occurs.

The data within the fetched row is returned as an array of strings, where each element of the array corresponds to a column in the result set. The order of the elements in the array matches the order of the columns in the SELECT statement. If a column's value is NULL in the database, the corresponding element in the returned array will also be NULL. It is important to note that mysqlfetchrow is part of the legacy MySQL C API and is deprecated. Newer applications should use the functions provided by the MySQL C API extension (often referred to as libmysqlclient) which offer more modern and robust ways to handle result sets.
