What does mysql_fetch_row() return?

This question is asking about the output of the mysql_fetch_row() function in MySQL.
mysql_fetch_row() is used to fetch a row of data from a result set (a collection of data retrieved from a database query).
Let's break down the options:
Option A: integer - This is incorrect. mysql_fetch_row() doesn't return a single integer value.
Option B: float - Also incorrect. It doesn't return a single floating-point number.
Option C: structure - This is incorrect as well. mysql_fetch_row() doesn't return a structured data type.
Option D: pointer - This is the correct answer! mysql_fetch_row() returns a pointer to an array that contains the fetched row data. Each element in the array represents a column value from the row.
In simpler terms, imagine you're retrieving a row from a table. mysql_fetch_row() gives you a pointer to where the data for that row is stored, making it easy to access the individual values.
