What potential issues can arise when storing SQL query results in arrays for further manipulation in PHP?

One potential issue that can arise when storing SQL query results in arrays for further manipulation in PHP is the risk of memory exhaustion if the result set is large. To solve this issue, you can process the results row by row instead of storing the entire result set in an array. 

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Execute the SQL query
$query = "SELECT * FROM table";
$result = $connection->query($query);

// Process the results row by row
while ($row = $result->fetch_assoc()) {
    // Manipulate the data here
}

// Close the database connection
$connection->close();
