PHP显示非十进制尾随零

Question

I have a number stored in MySQL:

5430

PHP only displays:

543

How can I retain the last zero? Some numbers do not contain zeros.

Answer 1

Try this:

$number = str_pad($number, 4, '0', STR_PAD_RIGHT);

This will turn 1 into 1000 or 123 into 1230 . If you wanted 0001 or 0123 , you can use STR_PAD_LEFT instead.

Here's the docs for str_pad() : http://php.net/manual/en/function.str-pad.php

Answer 2

try number_format()
