Multi-dimensional array and explode function in PHP

Question

I'm having a hard time to get my desired output regarding multi-dimensional array please help me out thankssss

Desired output:

[
    {
        "sku" : "11111",
        "qty" : "1"
    },
    {
        "sku" : "22222",
        "qty" : "1"
    },
    {
        "sku" : "33333",
        "qty" : "1"
    },
    {
        "sku" : "44444",
        "qty" : "1"
    }
]

My code:

$string = "11111*1; 22222*1; 33333*1; 44444*1";

$array  = explode('; ', $string);

foreach($array as $k=>$v){

  $array[$k] = explode('*', $v);

}

$key is not required in quickSwap answer:

    $string = "11111*1; 22222*1; 33333*1; 44444*1";
    $array  = explode('; ', $string);
    foreach ($array as $value) {
        list($sku, $qty) = explode('*', $value);
        $result[] = [
            'sku' => $sku,
            'qty' => $qty
       ];
    }

What's the difference if there's a key or not tho?

You just need to fetch those values in two different variables and just assign it to new variable say $result

$string = "11111*1; 22222*1; 33333*1; 44444*1";
$array  = explode('; ', $string);
foreach ($array as $k => $v) {
    list($sku, $qty)   = explode('*', $v);
    $result[$k]['sku'] = $sku;
    $result[$k]['qty'] = $qty;
}
echo json_encode($result);

json_encode — Returns the JSON representation of a value
list — Assign variables as if they were an array

Output

[{
    "sku": "11111",
    "qty": "1"
}, {
    "sku": "22222",
    "qty": "1"
}, {
    "sku": "33333",
    "qty": "1"
}, {
    "sku": "44444",
    "qty": "1"
}]

Demo.

EDIT

You can use array_combine to achieve the same.

foreach ($array as $k => $v) {
    $result[$k]   = array_combine(['sku', "qty"],explode('*', $v));
}

@noob_girl Difference is if we don't write any index like I wrote $k in my code, it will assign default keys of array which starts with 0 to increasing length of array, and last index of any array will be length of array -1. Instead of all that, I took keys which are already created in first explode.

so the output will still be the same?

Yes but for your scenario

You're currently iterate through the object correctly, but you need to build your array in the correct way, containing the key names:

$string = "11111*1; 22222*1; 33333*1; 44444*1";
$array  = explode('; ', $string);
$new    = [];

foreach($array as $k => $v){
    $parts = explode('*', $v);

    $new[] = [
        'sku' => $parts[0],
        'qty' => $parts[1],
    ];
}

Here's a demo

One option is to use array_map to loop thru the exploded string. Use json_encode to convert the array into a json

$string = "11111*1; 22222*1; 33333*1; 44444*1";

$result = array_map(function($v){
    $t =  explode("*", $v);
    return array( "sku" => trim( $t[0] ), "qty" => trim( $t[1] ));      
}, explode(";", $string));

echo json_encode( $result );

This will result to:

[{
  "sku": "11111",
  "qty": "1"
}, {
  "sku": "22222",
  "qty": "1"
}, {
  "sku": "33333",
  "qty": "1"
}, {
  "sku": "44444",
  "qty": "1"
}]

You can use array_walk, explode and json_encode with parameter JSON_PRETTY_PRINT

$string = "11111*1; 22222*1; 33333*1; 44444*1";
$strToArray = explode(';',$string);
$res=[];
array_walk($strToArray, function($v, $k) use (&$res){
  $res[$k] = [
    'sku' => substr($v, 0, strpos($v, '*')),
    'qty' => substr($v,strpos($v, '*')+1, strlen($v))
  ];
});
echo json_encode($res,JSON_PRETTY_PRINT);
