PHP : Get coordinates latitude/longitude from string
Problem :
Let say we are dealing with another program that produces coordinates (lat/long) in a string format that look like this :
"(142.6278389135, 43.29162915041)"
and we want to assign the float values into variables.
Solution :
Break the string with explode()
function, cast the string values into float with floatval() functions. See codes below :
<?php
$str = "(142.6278389135, 43.29162915041)";
// remove the parentheses
$clean = substr($str, 1, -1);
$coord = explode(', ', $clean);
$long = floatval($coord[0]); // cast string to float
$lat = floatval($coord[1]); // case string to float
echo "Long : ".$long."\r\n";
echo "Lat : ".$lat."\r\n";
?>
Output :
Long : 142.6278389135
Lat : 43.29162915041
