PHP format MySQL return float type method, Phpmysql return float

The example in this article describes how PHP formats MySQL to return a float type. Share to everyone for your reference, as follows:

PHP Gets the float field of MySQL, after the echo output, the decimal part contains more than 0.

You can use Floatval ($num) to leave 0.

To retain the decimal place, use Number_format ($num, 2);

The Number_format function rounds a value that exceeds the specified number of digits.

If you do not want to round, keep all decimals. You can use the following methods:

If you want to keep only two decimal places available Number_format ($num, 2); Echo f (' 1001.334534 ', 2). '
'; 1001.334534echo f ('-1001.000 ', 2). '
'; -1001.00echo f (' 1001.3 ', 5). '
'; 1001.30000echo f (' 1001.33 '). '
'; 1001.33echo f (' 1001.000 '). '
'; 1001//formatting decimals, but not rounding, if there are decimals are all reserved, no decimals add 0;function f ($num, $v = 0) {  $num = floatval ($num);  if ($v > 0)  {    $num = '. $num;    $arr = Explode ('. ', $num);    if (count ($arr) = = = 1)    {      $num. = '. '. Str_repeat (' 0 ', $v);    }    else    {      $v-= strlen ($arr [1]);      if ($v > 0)        $num. = Str_repeat (' 0 ', $v);    }  }  return $num;}
