Re: PHP array for use in javascript

Hi Céryl,

This was very useful for me as I'm trying to use flot as well.

I did something similar by first trying to build up an array of tuples
and then used the $javascript->object() function which produces a JSON
array which is perfect input for flot e.g.

foreach($data as $key => $val){
$flot_data[] = array( $key, $val ); //append onto flot_data array
}
$output = $javascript->object($flot_data);

Cheers,

Ian
