Are there any potential issues or drawbacks to using the "ceil()" function for rounding in PHP?

One potential issue with using the "ceil()" function for rounding in PHP is that it always rounds up to the nearest integer, which may not always be the desired behavior. To address this, you can create a custom rounding function that allows for more flexibility in rounding options. 

function customRound($number, $precision = 0, $mode = PHP_ROUND_HALF_UP) {
    $factor = 10 ** $precision;
    return round($number * $factor, 0, $mode) / $factor;
}

// Example usage
$number = 3.14159;
$roundedNumber = customRound($number, 2, PHP_ROUND_HALF_DOWN);
echo $roundedNumber; // Output: 3.14
