arrays - Randomly select item from JSON in PHP -

-

i have json string :

[{"format":"i25","content":"172284201241"},  {"format":"i25","content":"40124139"}, {"format":"i25","content":"20197086185689"}, {"format":"i25","content":"10215887"}, {"format":"i25","content":"702666712272"}, {"format":"qrcode","content":"3"}]

and want select 1 of these items randomly,for example :

{"format":"i25","content":"40124139"}

how can php?

that string looks lot json, decode array.

$array = json_decode($string, true);

then, pick random index:

$one_item = $array[rand(0, count($array) - 1)];

and convert json:

$one_item_string = json_encode($one_item); echo $one_item_string;
