Separate value in array more than one (implode)

Let say i have a string: 

"fruit: apple, fruit: orange, vegetable: carrot,"

i would like to to store it like this:

type[] => fruit,vegetable

item[] => apple,orange,carrot

can anyone help me on this?

Solution

  • here is a code that will parse your string into 2 arrays.

    <?php
$type=array();
$item=array();
$a="fruit: apple, fruit: orange, vegetable: carrot,";
foreach (explode(',',trim($a,',')) as $csv){
    list($k,$v)=explode(':',$csv);
    $k=trim($k);
    $v=trim($v);
    if($k && $v){
        if(!in_array($k,$type)) $type[]=$k;
        if(!in_array($v,$item)) $item[]=$v;
    }
}
print_r($type);
print_r($item);

    if you want the $type to be a CSV single string like in your question, you can use join like this:

    print join(',',$type);
