逗号分隔列表到一个对象数组，其值为php

Question

I'm basically just trying to get from this:

$value="20, 40, 40" 
$color="blue, green, orange"

To this:

var data = [ { value: 20, color:"blue" }, { value : 40, color : "green" }, { value : 40, color : "orange" }]

So I need to extract the value and color add put them item this array of objects. I know how this could be done if only value needed to be set, not color as well using explode and foreach, but I have not idea how to do this needing both values.

Any ideas are much appreciated.

Thanks,

David

Answer 1

explode两个数组，使用索引一次迭代两个，使用给定索引处的两个数组中的值来创建object / tuple / whatever，并在将它们存储在data 。

Answer 2

Do this

$value="20, 40, 40"; 
$color="blue, green, orange";


$explVal = explode(",", $value);
$explCol = explode(",", $color);

$arr = array();

for ($i=0; $i<count($explVal); $i++)
{
    $arr[$i]['value'] = $explVal[$i];
    $arr[$i]['color'] = $explCol[$i];
}

then do

$result =     json_encode($arr);

Answer 3

Are there always going to be the same number of values in each, then?

$value="20, 40, 40";
$color="blue, green, orange";

$values = explode(", ",$value);
$colors = explode(", ",$color);

$output = 'var data = [ ';
for($i = 0; $i < count($values) &&  $i < count($colors); $i++){
  $output .= '{ value: '.$values[$i].', color:"'.$colors[$i].'" }, ';
}
$output = substr($output,0,-2);
$output .= ']';

echo $output;

Result is:

var data = [ { value: 20, color:"blue" }, { value: 40, color:"green" }, { value: 40, color:"orange" }]
