WordPress get_option

One of the most frequently used features in WordPress (I judge by myself and by the themes I’ve worked with). It’s strange that I’m only describing it on my blog now.

get_option( $option, $default = false )
If the option with the specified name doesn’t exist and the $dafault parameter isn’t specified, the function will return false.

If the option is stored as a serialized string in the database, it will be decoded with maybe_unserialize() when returned.

Scalar non-string values will be converted to strings, e.g:

false option value will be returned as string(0) “”,
true will be returned as string(1) “1”,
0 will be returned as string(1) “0”,
1 will be returned as string(1) “1”;
Parameters #
$option
(string) The name of the option whose value we want to retrieve. We can either take the name of one of the standard WordPress options listed below , or we can find it out ourselves, I also told you how.
$default
(number|string|array|object) If you want to get some option on the site that doesn’t exist, then get_option() either returns false or whatever is specified in this second parameter.
WordPress standard options #
By “standard,” I mean those options that already exist on the pure WordPress engine, most of them accessible through the Settings menu.

I’ve listed them below, pre-dividing them into categories. In order to get any of them using get_option() function, you just need to pass the name of the option you want in the function, for example to get admin email we can use the code line $email = get_option(‘admin_email’ );
