Probleme with the function for decode data in php
Bonjour,
j'ai fait une fonction pour décoder les data en retour d'api. Pour les coordonnées GPS je n'ai pas toujours des coordonnées correct. Voici mon code en php avez vous une idée ou une lib pour faire ce travaille correctement ?
Hello,I did a function to decode the data back from API. For GPS coordinates I do not always have correct coordinates. Here is my code in php do you have an idea or a lib to do this works correctly ?
function convertGPS($degres , $minutes , $secondes ){

J'ai trouvé !!!!
