Formatting numbers from 1000 to 10.00

问题

I'll like to format 1000 to 10.00 The PHP number_format function does not seem to be working for this.

I have tried:

$amount2 = number_format("$cost",2,"",",");
echo "$cost";

Any ideas? Is there a way I can manupulate number_format to display the results (i.e just inserting a decimal before the last two digits?

回答1:

Number format will change the "." to a "," but you telling it to format ONE THOUSAND.

$cost=1000;
echo number_format($cost,2,'.',',');
//1,000.00

What you want is simply:

$cost=1000;
 echo number_format($cost/100,2,'.',',');
//10.00

回答2:

Is this legit for you ?

<?php
$cost=1000;
echo substr($cost, 0, 2) . "." . substr($cost, 2);//10.00

回答3:

1000 and 10.00 are totally different numbers (in values). Divide by 100, then format it properly:

$cost = 1000 ;
$cost /= 100 ;

$amount2 = number_format($cost,2,".","");
echo $amount2 ;

Try this code:

$stringA= 1000;
$length=strlen($stringA);
$temp1=substr($stringA,0,$length-2);
$temp2=substr($stringA,$length-2,$length);
echo $temp1.".".$temp2;     // Displays  10.00

回答5:

The third parameter to number_format should be the character you want to use as a decimal point. Why are you passing an empty string? And why are you placing your number ($cost) inside a string?

Try this: echo number_format($cost,2,'.',',');

EDIT: Perhaps I misunderstood your question — if you want the number 1000 to be displayed as 10.00, just divide $cost by 100 before calling number_format().
