如何检索序列化数组中的所有值

i'm trying to get all values in this array stored in wp_option table. The array is:

a:3:{i:0;s:11:"development";i:1;s:4:"apps";i:2;s:10:"creativity";}

What i need is just to get the values: development, apps, creativity.

I was trying:

$myOptions = get_option('hashtag');
foreach($myOptions as $option) {
echo $option;
}

but the output is:

developmentappscreativitydevelopmentappscreativitydevelopmentappscreativity

If i write:

var_dump ($option);

the output is:

string(11) "development" string(4) "apps" string(10) "creativity" string(11) "development" string(4) "apps" string(10) "creativity" string(11) "development" string(4) "apps" string(10) "creativity" 

Thanks in advance.

$myOptions = get_option('hashtag');

echo $myOptions[0]
