[SOLVED] Newbie: need help declaring arrays!

[OM2]

Can someone tell me what's wrong with the following:

 

$myNewArray = array();
$myNewArray[variable1] = "Hello world";
$myNewArray[variable2] = "Hello Universe";
$myNewArray[weirdName] = "Hello Everyone!";

 

If I have

error_reporting(E_ALL);

on the first line, this throws many errors.

 

The errors say something like:

Notice: Use of undefined constant variable1 - assumed 'variable1' in /home/user/public_html/dirs/dir2/dir3/myTest.php on line 5

 

I'm a bit lost, I didn't think there was anything wrong with my array declreation.

If I leave error_reporting(E_ALL); out, then all is OK!  But because it's throwing errors, I guess I must be doing something semantically wrong?

 

Thanks.

Try doing:

 

$myNewArray = array();
$myNewArray['variable1'] = "Hello world";
$myNewArray['variable2'] = "Hello Universe";
$myNewArray['weirdName'] = "Hello Everyone!";

 

The error indicates that PHP is looking for a constant defined earlier titled variable1 because variable1 is not defined in quotes inside your array arguement that is declaring it.

when you do $blah[something] php first checks to see if something is a constant. Since you did not make it a constant, it's throwing you that error.  However, if php fails to find a constant, it will treat it will then attempt to use it as a string like $blah['something'].  So...your code will work as intended, but you get that message.  To fix it, use the quotes around it as njoj pointed out.

aah... ok.  i will do this now.

just to confirm though, if i have:

$myNewArray = array();
$myNewArray['variable1'] = "Hello world";
$myNewArray['variable2'] = "Hello Universe";
$myNewArray['weirdName'] = "Hello Everyone!";

 

when i actually want to reference the items, should i use $myNewArray[weirdName] or $myNewArray['weirdName']?

 

thanks.

With the quotes would be best, you would probably get a warning similar to the original one if you did it without the quotes because PHP looks to see if you defined any constant called weirdName earlier in the script.

i'm marking this thread as solved.
