What potential issues can arise when using multiple JOIN statements in a PHP MySQL query?

When using multiple JOIN statements in a PHP MySQL query, potential issues can arise with duplicate column names from different tables, leading to ambiguous column references. To solve this issue, you can alias the columns in the SELECT statement to disambiguate them. 

$query = "SELECT table1.column AS column1, table2.column AS column2
          FROM table1
          JOIN table2 ON table1.id = table2.id";
$result = mysqli_query($connection, $query);

if($result) {
    while($row = mysqli_fetch_assoc($result)) {
        // Access columns using aliases
        $value1 = $row['column1'];
        $value2 = $row['column2'];
        // Process the values
    }
} else {
    echo "Error: " . mysqli_error($connection);
}
