Hash question

[PhoenixDown]

Can I make a hash like this:

%hash = (
'test' => 'test' => 'test' => 'test,
);
1;

If that's not currect, please show me the correct way to do this. Thanks.

A 'hash' is an associative array..... or, a collection
of key/value pairs. The pairs are separated by commas.
Each key must be unique.
Each key points (=>) to it's value.

%hash = ('key1'=>'value1','key2'=>'value2');
|___________| |____________|
first pair second pair

value1 is associated with key1
or, key1 points to value1

Sometimes, you might see another notation where that uses
just commas and not the '=>'.

%hash = ( 'key1','value1','key2','value2');
|__________| |_________|
first pair second pair

You appear to be using the same 'key' twice. Each key must be unique.
and
You need a comma between your key=>value pairs.
There are more examples in thread219-102565.

It's common when creating a hash to put each key/value pair on a separate line too. It makes it much easier to read and maintain. It's also allowable to have a comma after the last key/value pair. I usually do that so I don't forget to add it if I add a new key/value pair after the last. It's exactly the same syntax as goBoating has, just formatted more clearly. Here's what the common format looks like:

%hash = (
   'key1' => 'value1',
   'key2' => 'value2',
);
