Assigning Value of and Array Element as Key to Another Array

[Pavan PHP]

Hi All

This is a situation which comes to me while coding in php day in day out. I am trying to improve the way I write the code so looking for you suggestion. Please go through this and suggest me, If you have any idea how to do this a better way.

I have a $RAW['userid'] which contains actual user id of the user.

I have another array $USER[] which contains all the users id and their relevant values.

Suppose $RAW['userid'] have value 'pavan', I need to check whether $USER['pavan'] is set or not.

To do this, I use following code:

$temp_user_id = $RAW['userid'];
if(isset($USER["$temp_user_id"])) { echo "User Exists"; }

Is there any way to get this done without creating a new variable $temp_user_id?

Regards

if(!empty($USER[$RAW['userid']]))

I think you could write

if(isset($USER[$RAW['userid']])) { echo "User Exists"; }

Hi,

could you use something like this?

echo ($USER[$RAW['userid']]<>'')?'User Exists':'';

or

$string=($USER[$RAW['userid']]<>'')?'User Exists':'';
echo $string;

or as you want

$string=(isset($USER[$RAW['userid']]))?'User Exists':'';
echo $string;

Cheers!
