I'm not sure if I'm allowed to ask these types of questions. Anyway, I have this array value $custom_fields['user_gender'][0] that outputs this:
a:2:{i:0;s:7:"Male";i:1;s:7:"Female";}
I'm not sure how to convert this into an array or string.

I assume you use PHP?edwardmp– edwardmp2014-11-17 01:15:47 +00:00Commented Nov 17, 2014 at 1:15

You might be allowed if you make your question a little bit more clear. Such as on which language do you want to use it? I am guessing php, am I right?guness– guness2014-11-17 01:16:22 +00:00Commented Nov 17, 2014 at 1:16

The example data looks like it is serialized PHP. Serializing is a way an array, string etc. can be "represented" as a textual string and can later be converted back to the original data format, using a unserialize operation. A serialized string can be stored as text in a database and can be unserialized at any point.
You can unserialize it with:
$array = unserialize($custom_fields['user_gender'][0]);
This should return an array. If you var_dump on $array, you can be sure it's an array.

Will accept this answer in a few mins. Anyway, it outputs this
array(2) { [0]=> string(5) "Male" [1]=> string(6) "Female" } how do I let it show only Male and Female?

Yes it is an array. You can use
$array[0] for male and $array[1] for female.user2772219
I have a follow up question. I did this:
$user_gender = unserialize($custom_fields['user_gender'][0]); And then I did this $user_gender = array_map('strtolower', $user_gender); But I get this error 'Warning: array_map(): Argument #2 should be an array'edwardmp
As the error tells,
$user_gender is not an array, it is a string. If you just want to lowercase the string just use strtolower($user_gender) instead. The array_map would apply that function to every string in array, but using it on a string is not going to work.
