1Are you sure you want to encrypt an array? Quite unusual operation and unnecessary most of timeYour Common Sense– Your Common Sense2010-04-08 06:40:10 +00:00Commented Apr 8, 2010 at 6:40

You can encrypt/decrypt something like this:
$arr_value = array("1","2","3","4");
function encrypt($text)
{
return base64_encode($text);
}
function decrypt($text)
{
return base64_decode($text);
}
Now to encrypt:
$encrypted = array_map("encrypt", $arr_value);
echo '<pre>';
print_r($encrypted);
And to decrypt:
$decrypted = array_map("decrypt", $arr_value);
echo '<pre>';
print_r($decrypted);
.
Note:
It is worth having a look at a better way of encryption library:

hmm... but it seem like only allow to encript for string but not array

@Jin Yong: No actually the
array_map function walks through entire array thus encrypting/decrypting each value of the array hence the entire array :)Jin Yong
right, but do there have any way that we can use base64_encode come with password ot secret code?
Sarfraz
@Jin Yong: Yes you can encrypt secret codes of course. I would suggest you to encrypt like told in the link i posted on top of my answer. Thanks

i tried the code that show on the link... Fatal error: Call to undefined function mcrypt_encrypt() show when i run the code

if you encrypt/decrypt string then use .
$str_value = $arr_value.join(",");
encrypt/decrypt $str_value
$arr_value=$str_value.split(",")
