/**
|
|
* 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 `$default_value` value
|
|
* is returned if provided. If not, boolean `false` is returned.
|
|
* 2. When one of the Options API filters is used: {@see 'pre_option_$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
|
|
* }
