What potential issues could arise from using mysql_fetch_row incorrectly in PHP?

Using mysql_fetch_row incorrectly in PHP can lead to errors such as accessing data in an incorrect order or missing rows of data. To avoid these issues, it is important to properly handle the returned data array and ensure that the correct index is used to access each field.

// Correct way to use mysql_fetch_row in PHP
$result = mysql_query("SELECT * FROM table");
while($row = mysql_fetch_row($result)) {
    // Access each field using the correct index
    $field1 = $row[0];
    $field2 = $row[1];
    // Process data as needed
}
