What are the potential pitfalls of using base_convert() in PHP compared to MySQL CONV()?

The potential pitfalls of using base_convert() in PHP compared to MySQL CONV() include differences in handling large numbers, precision, and performance. To mitigate these issues, you can use MySQL CONV() directly in your SQL queries to convert numbers between different number bases efficiently and accurately. 

// Example of using MySQL CONV() in PHP
$number = 123;
$fromBase = 10;
$toBase = 16;

$query = "SELECT CONV($number, $fromBase, $toBase) AS converted_number";
$result = mysqli_query($connection, $query);

if ($result) {
    $row = mysqli_fetch_assoc($result);
    $convertedNumber = $row['converted_number'];
    echo "Converted number: $convertedNumber";
} else {
    echo "Error executing query: " . mysqli_error($connection);
}
