[SOLVED] How do I determine the data type of any variable?

How do I determine the data type of any variable? any function available?

 

I'm having trouble because i do a

 

print_r($var);

 

and it outputs

 

Array ( .... )

 

but when i do an

 

array_key_exists("something",$var)

 

it returns says second argument must be array or object

 

im confused. even

 

is_array($var)

 

returns true

The function is http://sg.php.net/manual/en/function.gettype.php

 

I'm interested to see what it returns for your mystery variable..

btherl, i modified my message above

[obay]

okay i used

 

gettype($var)

 

it returned "array". but array_key_exists() still doesn't recognize $var as an array

 

what's wrong?

[dbillings]

show us all the code not just chunks

Can you post a short script reproducing the problem?  If that's not possible, please post your entire script.

really weird.. the code works now... i.e. array_key_exists()...

 

im confused why...  ??? ??? ???

 

but anyway, it works now... sorry for wasting your time guys..

The most likely reason is that you accidentally changed the value of $var and didn't realize it.  Then you didn't realize when you fixed the code that changed it either

 

The other most likely reason is a typo in a variable name, but that's unlikely for such a short name.

Yes, i must have done something to the code i didn't notice. Thanks though!!! =)
