Having trouble with array. Adding key => value when key is variable.

[Anti-Moronic]

Title says it all really. I have no idea if I am doing this correctly or effectively.

 

Here's my array:

 

<?php

$arr = array(

"key1" => "val1",


)

//To add a key => val I use:

$arr['key'] = "val";

?>

 

That works fine, but I can't assign a key=>val unless the key is literal and within single quotes. For example, this doesn't work:

 

$key=key2;

 

$arr[$key] = "val";

 

Any advice on how I should be going about this. Maybe a better way of adding elements to my array (while being able to set custom keys).

 

Thanks.

if you want to add the array elements dynamically () the the second approach

$arr['key'] = "val";

is better

That's not what I'm trying to do. Thanks any way.

 

I'm trying to assign the key dynamically.

yes you can assign key dynamically as

 

$k="yourkey";

$ar[$k] = "value";
