To convert degree to radians and radians to degree following function are used:
<?php
//degrees to radians function
function DegToRad($degrees)
{
return $degrees * 3.14 / 180;
}
//radians to degrees conversion
function RadToDeg($radians)
{
return $radians * 180 / 3.14;
}
?>
Let's have a example to test the above function:
<?php
//calling the function to convert degree to radians
echo DegToRad(90);
echo "<br>";
//calling the function to convert radians to degree
echo RadToDeg(0.707);
?>
