Remove a decimal place in PHP

In PHP, I am getting numbers from a database with 3 decimal places. I want to remove the last decimal point. So 2.112 will become 2.11, 23.123 will become 23.12 and 123.267 will become 123.26. Its like doing a floor at a decimal level.

Solution

  • You can use number_format, you specify the number of decimal places as the second arugment.

    Example

    $number = 534.333;

echo number_format($number,2) // outputs 534.33

    Or use round 

    $number = 549.333;
echo round($number, 2) // outputs 534.33

    Seems like substr is what solved the question in the end 

    substr($number,0,-1); // everything besides the last decimal
