从字符串转换为数字的问题

Question

I have a variable $totalprice with number 1,072.00.

If I use int($totalprice) or number_format($totalprice), it outputs 1.00.

How can I solve this problem? I want 1072.00

Answer 1

$totalprice = (float)str_replace(',', '', $totalprice)

That will get you a normal float representation of the number. You can then apply the number_format function to that to get the desired output.

Perhaps you should rethink your handling of numbers. How in the first place the number gets the format 1,072.00 ? You shouldn't do any formatting to it until outputting to the browser, so the number should always be in the 1072.00 format.

Answer 2

Problem you are having is about locales. To avoid issue about money formatting i would suggesT you to use

string money_format ( string $format , float $number )

By using this function you can format the number according to desired format. you can read more about this function and what formatting type to use here: money_format

Answer 3

It is not a bug ,because your number is parsed from left till first invalid character (the , )

so 1,072.00 is really 1 ,072.00 , and just the bold section is parsed when you are trying to convert the string to number.
