Using PHP, how can I convert a value in
POINT datatype to a string like
POINT (-34.601020 -58.371020) (an ouput in WKT or GeoJSON is preferable)
If I echo the raw value, I get weird characters.
I’ve tried using
bin2hex and then tried to convert the hex to string but with no luck.
I’m aware of MySQL’s
AsText(), but I would like to do it in PHP.
Finally I’ve got this working!!!
I had to use unpack in order to extract the binary data from MySQL
$point_value = $data_from_db["point_field"]; $coordinates = unpack('x/x/x/x/corder/Ltype/dlat/dlon', $point_value); echo $coordinates['lat']; echo $coordinates['lon'];
Here is a tutotial that helped me with this issue
