how can i recive an array from an html get form?
i would receive the value of same checkbox, they have all the same name "es. object"
Not sure I'm completely understanding your question but if you name your elements in the following way they will become ad array:
<input type="checkbox" name="lang[ ]" value="en">English<br />
<input type="checkbox" name="lang[ ]" value="fr">Français<br />
<input type="checkbox" name="lang[ ]" value="es">Español<br />
