通过ajax将数组传递给php
问题描述：
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...
我通过ajax将数组传递给php。 p>
$交（ “send.php”，{ARR：ARR}）。 // [“one”，“two”，“three”]
code> pre>
如何在php中为变量分配每个值？ 我尝试了这个，但没有做我需要的。 p>
for（$ i = 0; $ i＆lt; $ _POST ['arr']; $ i ++）{
$ var +（$ i + 1）= $ _POST ['arr'] [$ i];
}
code> pre>
预期$ var1 =“one”，$ var2 =“two”等... p>

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];
