### How to calculate a percentage in php

In this tutorial we'll cover how to calculate a percentage using php and display the result with some decimal points.

In the example below, we have two numbers. One is our base upon which our percentage will be calculated and the other is the value to determine the percentage.

We will be using the number_format() function to determine how many decimal points our result will have, as well as to set the separator.

``````
\$possible_mark = 100;
\$my_mark = 78;
\$percentage_achieved = (\$my_mark / \$possible_mark) * (100);
\$percentage_achieved = number_format((float)\$percentage_achieved, 2, '.', '');
echo \$percentage_achieved . "%";
``````
The output from the above code will will be: 78.00%

The best apology is one which involves you not repeating those same mistakes aga
