You haven't provided the data that gets outputted from your php, so it's hard to say.

But the first item in each of the columns array determines the name that goes in the legend. So:

columns: [
    ['this is legend 1', 30],
    ['put your value here', 120], 
]

would result in the legend labels being "this is legend 1" and "put your value here".

Here's a fiddle: http://jsfiddle.net/jrdsxvys/9/

Edit... Another option is to use the names property, as done here: http://jsfiddle.net/jrdsxvys/40/

data: {
    columns: [
      ['d1', 30],
      ['d2', 120]
    ],
    type: 'pie',
    labels: true,
    names: {
      d1: 'some name here',
      d2: 'another name'
    }
}
