    Is that some kind of factor? You can’t just multiply by 100 and round?

  • @utluiz Ta ta already solved!

    Okay, I saw that you accepted the answer and got the expected result. But using string manipulation over numerical values sounds like a beautiful gambit to me. What if the result of the split is something like 1.23?

  • @utluiz ai vai meio q ser inutil o str_replace e continuar normal neh..?

    Yeah, and that’s called inconsistency.

  • @utluiz was what I said clearly in the answer, as it is not possible to be sure which objective of the code has no way to affirm a better path, since to catch the value after the point number already sounds strange by itself.

  • is an evaluation system, for example if you have 20,000,000 votes on 5 stars and the total votes on all stars is 35,000,000 will give 0.57 and you will get that 0. always q need to withdraw to put the value="57" in the bar Progress

I don’t know if to say what the best way to do it is because I don’t know what the goal will be, since your code seems to me something with a percentage but I can’t be sure what you really want to do

However you can try:

round(($ratings[5]/$idMark), 2) * 100;

Or you can try to convert to string and take the 0. com str_replace (I believe php already converts to string when we use functions with str_ for example):

str_replace('0.', '', round(($ratings[5]/$idMark), 2));

But it’s like I said, I do not know if it is the best way, because I do not know what the purpose of the code.

If you are working with percentage (which is not certain due to variable $ratings[5]) you could just do so:

round(($ratings[5] / $idMark) * 100);

  • And I used str_replace, it worked :D, thank you very much
