使用字符串键插入新的PHP数组值

I am able to create array values using

$array = array("key" => "value" ... );

Now I want to add them dynamically after assigning the value to $array

you can access your array by using [] so

$array["new_key"] = "new value";

<?php
$array = array(
    "foo" => "bar",
    42    => 24,
    "multi" => array(
         "dimensional" => array(
             "array" => "foo"
         )
    )
);

var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>

This helps you. Refer the php documentation of arrays.
