PHP Decimal Place Handling
            
                
                Print
            
        
        
        
        
            The goal here is to show the different method for dealing with decimal places on a floating number.
<?php
// Example
  $float = '100.12345';
// Round
  echo round($float, 2);
// Floor with floor()
  echo floor($float * 100) * 0.01;
// Floor by INT casting
  echo (int)($float * 100) * 0.01;
// Ceiling with ceil()
  echo ceil($float * 100) * 0.01;
// Trim using sprintf()
  echo sprintf("%.2f", $float);
// Trim using number_format()
  echo number_format($float, 2, '', '.');
?>
