PHP Numeric formatting Sample code

More often than not, we need to format the numbers, such as the number of bits in front plus 0. PHP can be easily implemented, because PHP comes with functions related to functions.

The Number_format () function formats numbers by using thousands of groupings.

For example, Echo Number_format (285266237);

Can output 285,266,237

In addition, if you need to format the size of the file byte, the following methods can be drawn:

function Byte_format ($input, $dec =0)    {      $prefix _arr = Array (' B ', ' K ', ' M ', ' G ', ' T ');     $value = Round ($input, $DEC);     $i =0;     while ($value >1024)     {       $value/=;      $i + +;     }     $return _str = Round ($value, $dec). $prefix _arr[$i];     return $return _str;    }    echo Byte_format (285266237);

Display result is 272M

For example, Echo Number_format (285266237);
Can output 285,266,237
In addition, if you need to format the size of the file byte, the following methods can be drawn:

 function Byte_format ($input, $dec =0) {$prefix _arr = array (' B ', ' K ', ' M ', '     G ', ' T ');     $value = Round ($input, $DEC);     $i = 0;      while ($value >1024) {$value/= 1024;     $i + +;     } $return _str = Round ($value, $dec). $prefix _arr[$i];    return $return _str; } Echo Byte_format
