从值中获取数组中的特定MySQL数据？

I want to get a specific value out of a MySql database.

I have:

SELECT option_value 
FROM wp_options 
WHERE option_name = 'DevloungePluginSeriesAdminOptions'

Which outputs:

a:4:{s:11:"add_content";s:4:"true";s:7:"content";s:45:"155000009-9a5sg2t42q2k0159ko8hkdo85hjlu69j";s:11:"show_header";s:4:"true";s:14:"comment_author";s:4:"true";}

I think this is some sort of array. I don't know how handle it. I only want the 155000009-9a5sg2t42q2k0159ko8hkdo85hjlu69j part of the string.

How can I get just 155000009-9a5sg2t42q2k0159ko8hkdo85hjlu69j?

This data is in serialized format. You need to unserialize it before extracting the array value.

Suppose result object is $result, then following code will work:

$option_value = unserialize( $result->option_value );
$output = $option_value['content'];

put the value in a variable and unserialize:

$val = unserialize( $val );

You'll get a PHP array as a result, inspect it with

print_r( $val );
