Array Problem

intervelopment

Hey All,

I have an array which is like the following

Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 [8] => 0 [9] => 0 )

I have called the array $myarray

When i run

if(empty($myarray)){ echo 'Its all empty'; }

It doesnt work ... It should return the string 'Its all empty' but its not.

Can someone please let me know where im going wrong?

Cheers,

That array is far from empty - it's got 10 elements in it! Why would you think that is empty?

HA .. Well, that would be the reason its not working .... is there any way to return an error if all the elements have a value of 0?

Well, since 0 will translate to boolean false, you could use [man]array_filter/man with no callback function specified to remove all such entries. Thus, if you wanted to test for emptiness in that regard, you could do:

if(empty(array_filter($myArray)))

instead.

That worked a treat .. Thanks for your help
