# PHP Math Exercises : Get the distance between two points on the earth

## PHP math: Exercise-12 with Solution

Write a PHP function to get the distance between two points on the earth.

Pictorial Presentation: Sample Solution:

PHP Code:

``````<?php
function lat_long_dist_of_two_points(\$latitudeFrom, \$longitudeFrom, \$latitudeTo, \$longitudeTo){
\$pi = pi();
\$x = sin(\$latitudeFrom * \$pi/180) *
sin(\$latitudeTo * \$pi/180) +
cos(\$latitudeFrom * \$pi/180) *
cos(\$latitudeTo * \$pi/180) *
cos((\$longitudeTo * \$pi/180) - (\$longitudeFrom * \$pi/180));
\$x = atan((sqrt(1 - pow(\$x, 2))) / \$x);
return abs((1.852 * 60.0 * ((\$x/\$pi) * 180)) / 1.609344);
}
// Distance from New York to London
echo lat_long_dist_of_two_points(40.7127, 74.0059, 51.5072, 0.1275).' mi'."\n";
?>
```
```

Sample Output:

```3458.8601748984 mi
