How to calculate a percentage using php

[Joseph Cobham]

Hello,

I am having some problems calculating a percentage of a number using php.

For example if i have a questionnaire that users answer on my site and the number of answers is tabulated to be 2662 and i want to calculate the percentage of yes answers from no how do i go about it?

P.S i also know how to get the number of yes and no but i don't know how to calculate the percentage of yes and no.


Any help would be appreciated thank you.
Thank you.

percentage = (# of yes) / (# of responses) * 100

hi Joseph

calculating percentage is a coomon formula, there is nothing special in PHP

for e.g.

total no. of answers = 2662
correct answers = 2000

so % of total answers (2000 / 2662) * 100 = 75%

hope this helped.
