How to convert a string of numbers in a number with the last two digits always decimal (though 00)

Question

I have strings of numbers like this:

- 00986756849

- 007478599700

- 004583930237345

I need to convert these strings of numbers into new numbers with the last two decimal values in PHP, ie:

- 009867568.49

- 0074785997.00

- 0045839302373.45

How to?

@RuslanOstafiychuk His question isn't about leading zeroes, it's about 2 decimal digits. — Barmar, Jan 02 '15 at 10:14
you should explode the last two digits and then concate "." value — Arun, Jan 02 '15 at 10:15

Get the string value . use substr_replace to replace a sub string or insert a substring to a specific position in the string :)

$str = "00986756849";

substr_replace($str,".",strlen($str)-2,0);

Also to say is that every number with a 0 at the start is interpreted as an octal number!(If you use it as a number) (Otherwise the solution is good :D) – Rizier123 Jan 02 '15 at 10:20

@Rizier123 and how to fix this? – Jan 02 '15 at 10:25
@JohnSam Just remove them. `$str = ltrim($str, "0");` – Rizier123 Jan 02 '15 at 10:31
@Rizier123 there isn't. – Jan 02 '15 at 10:35

$intNumber = (int) $stringNumber;
$decimalNumber = sprintf('%02d', $intNumber);

You need to divide the number by 100. – Barmar Jan 02 '15 at 10:16
Also, `(int)$stringNumber` will treat a number that starts with `0` as octal. – Barmar Jan 02 '15 at 10:16

You can try this

//$str = "10";
$str = "00986756849";
$str_length = strlen($str);
if($str_length>2)
{
    $output = substr_replace($str,".",$str_length-2,0);
}
else
{
    $output = substr_replace($str,".00",$str_length,0);
}
echo $output;
