cloudll Posted November 23, 2014 Share Posted November 23, 2014 I have made a 'health bar' for a simple browser game i have been working on. I want to use a background image to fill the health bar, so if for example, the player had full health, the health bar image width would be 100% is it possible to say set, the characters max health and the characters actual health and work it out as a percentage so i can stretch the image width as far as it needs to go? sorry if i haven't been too clear, my understanding of maths is not so good. Thanks for any tips. Link to comment https://forums.phpfreaks.com/topic/292662-percentage-help/ Share on other sites More sharing options...

Barand Posted November 23, 2014 Share Posted November 23, 2014 either of these echo number_format($health_percentage, 2); // 2.50 printf('%0.2f', $health_percentage); // 2.50 Link to comment https://forums.phpfreaks.com/topic/292662-percentage-help/#findComment-1497425 Share on other sites More sharing options...
