[hui2008]

In the js I can write like this:

header = Ext.extend(Ext.Toolbar,{
items:['-',{text:'tool1','-',{text:'tool2'}]
});
Ext.reg('headers',header);

now I can't the '-'

$head = array();
$head[] = array(
'-',///???????? how to do write this?
"text"=>"tool1"
);
$head[] = array(
"text"=>"menu2"
);

who can help me?

Look at the json_encode() of that:
[{"0":"-","text":"tool1"},{"text":"menu2"}]

You need:
["-",{"text":"tool1"},"-",{"text":"menu2"}]

Here's the code you need. Put the '-' as the first string in the array, before you make the other objects.

$head = array();
$head[] = "-";
$head[] = array("text"=>"tool1");
$head[] = "-";
$head[] = array("text"=>"menu2"); 

echo json_encode($head); 

if I was understanding you correctly...the Javascript provided was missing a curly brace, so I'm assuming you wanted to two objects in the array...

Let me know if you need anything else.

Edit: You might need an extra set of quotes to make ext see the -'s as strings...fyi.
