# #Distance Between a Point and a Line

It’s possible to calculate the shortest distance between a point and a `Line`. As `Polyline` and `Polygon` are also built upon the `Line` class it’s also possible to calculate distances from a point the polyline/polygon by iterating over their segments.

The following image explains how the distance is calcualated: P and R are located in such a way that the nearest distance to the line is the distance between P, R and the line end points. Point Q is nearer to the actual line than to any of the end points, so the actual distance is the perpendicular distance between Q and the line. ## #Example

``````<?php

use Location\Coordinate;
use Location\Distance\Vincenty;
use Location\Line;
use Location\Utility\PointToLineDistance;

\$point = new Coordinate(52.5, 13.5);
\$line = new Line(
new Coordinate(52.5, 13.1),
new Coordinate(52.5, 13.1)
);

\$pointToLineDistanceCalculator = new PointToLineDistance(new Vincenty());

printf(
'Distance from point to line: %.1f meters%s',
\$pointToLineDistanceCalculator->getDistance(\$point, \$line),
PHP_EOL
);
``````

The code above will produce the output below:

``````Distance from point to line: 27164.1 meters
