showing array content wordpress

Question

I am new in wordpress and I confuse how to solve this.

$redeem = array(
  date('Ymd'),
  $_POST['value']
);

if ($point && is_array($point)) {
  $n = sizeof($point);
  $point[$n] = $redeem;
   }

  update_user_meta(get_current_user_id(), 'value', $point);
} else {
  update_user_meta(get_current_user_id(), 'value', $redeem );
}

This code work properly, it makes the data in my database become array. The problem is, how can I show the data from my database into my work page ?

a:3:{i:0;s:8:"20160421";i:1;s:3:"222";

This is the result of value in my database. I just want to show the value of "222".

Thanks

this is a serialized odject, so you want to use unserialize() function over that object: php.net/manual/en/function.unserialize.php — mitkosoft

In WordPress, when you insert/update array data into user_meta or post_meta table, it will automatically saves data in serialized form, so you have to unserialize those data while fetching.

Below you can find simple conversation for array to serialized data and serialized data to array. You have to pass serialized data into unserialize function to fetch 222 value.

$arr = array("name"=>"milap","language"=>"php","cms"=>"WordPress");
$sd  = serialize($arr);
$res = unserialize($sd);
echo "<pre>";print_r($res);

The output of above code is,

Array
(
    [name] => milap
    [language] => php
    [cms] => WordPress
)

hey, I try that and I got this as the result: Array ( [0] => 20160421 [1] => 222 [2] => Array ( [0] => 20160421 [1] => 101 ) [3] => Array ( [0] => 20160421 [1] => 100 )

Can you explain how to fetch the 222 value right after this ?

Milap Over a year ago

If you have variable $val, Just access element $val[1] to get 222 value from array.

I mean not just accessing the value but also to write it into my work page. I already try to echo it but it doesnt work. I tried: echo $res[1];

I am confused, please write down your output array.
