Removing decimal point from number

I am looking to convert a decimal string, so it outputs without the decimal.

The following works correctly, outputting '13495' as an INT.

$current_total = intval(str_replace(".","","134.95"));

Is there any reason why this method shouldn't be used?

No reason why not. Depends on what you want to use it for. – dpDesignz Aug 19 '19 at 10:37
how many decimal places are you working with? – Will Aug 19 '19 at 10:40
@Will 2 decimal places. – ccdavies Aug 19 '19 at 10:41

$newTotal = $current_total * 100; – Will Aug 19 '19 at 10:42
@Will Thanks. I tried this already and it created a float, rather than an INT – ccdavies Aug 19 '19 at 10:42
if is need to be INT, you need add `(int)` so it should be `$newTotal = (int) ($current_total * 100);` otherwise it will be still decimal/float data type. – Hekimen Aug 19 '19 at 10:43
@Hekimen This returns '13400', not '13495' - Any ideas? – ccdavies Aug 19 '19 at 10:46
yea i forgot brackets, already edited ;) – Hekimen Aug 19 '19 at 10:46
@Hekimen Thanks, but this outputs '13494', instead of '13495'. – ccdavies Aug 19 '19 at 10:49
Apparently here is problem with float numbers, you can read more about this here [https://stackoverflow.com/questions/588004/is-floating-point-math-broken](https://stackoverflow.com/questions/588004/is-floating-point-math-broken), to my knowledge PHP don't have decimal data type which solve this problem, so i guess in your case will be better to stick with your code and work with numbers as with strings. – Hekimen Aug 19 '19 at 11:38
