$getJSON x populate array

[webstyler]

Hi, with jquery:

I need to send id to script and return array..

I have try with $.get but don't work

now, I have try with JSON but nothin :'(

I have my first_page.php

Here I have try this

var mycontacts = new Array();
$.getJSON("log.php",{id: "5"}, function(ps){
for (var i = 0; i < ps.length; i++)
{
listacontattijs[i] = new Array('ps[0].idd', 'ps[1].email', 'ps[2].nome','ps[3].idg');
}
});

The file called set.php make a correct structure as
[{idc: 22, email: [e-mail], nome: Myname, idg: 3},{idc: 22, email: [e-mail], nome: Myname, idg: 3},{idc: 22, email: [e-mail], nome: Myname, idg: 3}]

Any help?

I have try this:

var mycontacts = new Array(); 
$.getJSON("log.php",{id: 5}, function(ps){ 
for (var u = 0; u < ps.length; u++) 
      { 
       mycontacts[u] = new Array(ps[u].idd, ps[u].email, ps[u].nome, ps[u].idg); 
       console.log(mycontacts[u][1]); 
      } 
}); 
console.log(mycontacts); 

the first console (firebug) output is OK
the second, out of function and $.getJSON result nothing: [ ]

?

seems that var is empty after function.. but is global

Nb. var is defined before

help pls
