hi
i have a results from a python file ( i don't know python it is from someone else) and it looks like that:

["title1" =>1442,"title2" =>16664,"title3" =>555,"title4" =>65,"title5" =>234]

i need to make this into that to show in morris chart:

        $donutvalues = array(
            array( 'label' => "air" , 'value' => 125) ,
            array( 'label' => "light" , 'value' => 40),
            array( 'label' => "rest" , 'value' => 10 )
            );
        echo json_encode($donutvalues );

Open in new window


when i return this to the ajax call it works. so i need to prepare what comes back from the python file to this sort of array.
so i need the titles to be the values of the label, and the numbers to be the values of the value.

There is no correlation between

["title1" =>1442,"title2" =>16664,"title3" =>555,"title4" =>65,"title5" =>234]

and the output you posted!?!?!?!

maybe i didn't explained myself correctly, sorry.

title1,2,3, and so on should be placed in the inner arrays where at the moment there is "air","light","rest" and so on.

the numbers should be placed in the inner arrays as the values of the value key.

i need a loop over what comes in and make it return an array like $donutvalues .

thanks for answering

greetings derrida, this is about taking apart the String from the python file in PHP and pushing the string pieces into an array, You can try this code below to see if it does it -

$str1 = '["title1" =>1442,"title2" =>16664,"title3" =>555,"title4" =>65,"title5" =>234]';
  // string above is what you gave

// below I take out all string content not relevant and add some ','
$order = array('[', ']','"',' ','=>');
$replace = array('', '','','',',');
$str1 = str_replace($order, $replace, $str1);

// get all of the separate pieces into an array
$array1 = explode(',', $str1);
$len = count($array1);
// create the json array next
$jAry = array();
for ($i=0; $i< $len; $i+=2) { // add an array to json ary for each title
   $jAry[] = array('label' => $array1[$i] , 'value' => (int) $array1[$i + 1]);
   }
echo json_encode($jAry);
