/**
* Option API
*
* @package WordPress
* @subpackage Option
*/
/**
* Retrieves an option value based on an option name.
*
* If the option does not exist, and a default value is not provided,
* boolean false is returned. This could be used to check whether you need
* to initialize an option during installation of a plugin, however that
* can be done better by using add_option() which will not overwrite
* existing options.
*
* Not initializing an option and using boolean `false` as a return value
* is a bad practice as it triggers an additional database query.
*
* The type of the returned value can be different from the type that was passed
* when saving or updating the option. If the option value was serialized,
* then it will be unserialized when it is returned. In this case the type will
* be the same. For example, storing a non-scalar value like an array will
* return the same array.
*
* In most cases non-string scalar and null values will be converted and returned
* as string equivalents.
*
* Exceptions:
* 1. When the option has not been saved in the database, the `$default` value
* is returned if provided. If not, boolean `false` is returned.
* 2. When one of the Options API filters is used: {@see 'pre_option_{$option}'},
* {@see 'default_option_{$option}'}, or {@see 'option_{$option}'}, the returned
* value may not match the expected type.
* 3. When the option has just been saved in the database, and get_option()
* is used right after, non-string scalar and null values are not converted to
* string equivalents and the original type is returned.
*
* Examples:
*
* When adding options like this: `add_option( 'my_option_name', 'value' );`
* and then retrieving them with `get_option( 'my_option_name' );`, the returned
* values will be:
*
* `false` returns `string(0) ""`
* `true` returns `string(1) "1"`
* `0` returns `string(1) "0"`
* `1` returns `string(1) "1"`
* `'0'` returns `string(1) "0"`
* `'1'` returns `string(1) "1"`
* `null` returns `string(0) ""`
*
* When adding options with non-scalar values like
* `add_option( 'my_array', array( false, 'str', null ) );`, the returned value
* will be identical to the original as it is serialized before saving
* it in the database:
*
* array(3) {
* [0] => bool(false)
* [1] => string(3) "str"
* [2] => NULL
* }
*
* @since 1.5.0
*
* @global wpdb $wpdb WordPress database abstraction object.
*
* @param string $option Name of the option to retrieve. Expected to not be SQL-escaped.
* @param mixed $default Optional. Default value to return if the option does not exist.
* @return mixed Value of the option. A value of any type may be returned, including
* scalar (string, boolean, float, integer), null, array, object.
* Scalar and null values will be returned as strings as long as they originate
* from a database stored option value. If there is no option in the database,
* boolean `false` is returned.
