通过ajax将数组传递给php

Question

I'm passing an array via ajax to a php.

$.post("send.php",{arr:arr}); //["one", "two", "three"]

How do I assign each value to an variable in php? I tried this but does not do what I need.

for ($i = 0; $i < $_POST['arr']; $i++){
   $var+($i+1) = $_POST['arr'][$i];
}

expected $var1 = "one", $var2 = "two",etc...

You are trying to create a dynamic variable name. You'll have to wrap the $var with {} and concatinate with . to create dynamic variables.

 ${"var" . ($i+1)} = $_POST['arr'][$i];
