This could be used to check whether you need 14 * to initialize an option during installation of a plugin, however that 15 * can be done better by using add_option() which will not overwrite 16 * existing options. 17 * 18 * Not initializing an option and using boolean `false` as a return value 19 * is a bad practice as it triggers an additional database query. 20 * 21 * The type of the returned value can be different from the type that was passed 22 * when saving or updating the option. If the option value was serialized, 23 * then it will be unserialized when it is returned. In this case the type will 24 * be the same. For example, storing a non-scalar value like an array will 25 * return the same array. 26 * 27 * In most cases non-string scalar and null values will be converted and returned 28 * as string equivalents. 29 * 30 * Exceptions: 31 * 32 * 1. When the option has not been saved in the database, the `$default_value` value 33 * is returned if provided. If not, boolean `false` is returned. 34 * 2. When one of the Options API filters is used: {@see 'pre_option_$option'}, 35 * {@see 'default_option_$option'}, or {@see 'option_$option'}, the returned 36 * value may not match the expected type. 37 * 3. When the option has just been saved in the database, and get_option() 38 * is used right after, non-string scalar and null values are not converted to 39 * string equivalents and the original type is returned. 40 * 41 * Examples: 42 * 43 * When adding options like this: `add_option( 'my_option_name', 'value' )` 44 * and then retrieving them with `get_option( 'my_option_name' )`, the returned 45 * values will be: 46 * 47 * - `false` returns `string(0) ""` 48 * - `true` returns `string(1) "1"` 49 * - `0` returns `string(1) "0"` 50 * - `1` returns `string(1) "1"` 51 * - `'0'` returns `string(1) "0"` 52 * - `'1'` returns `string(1) "1"` 53 * - `null` returns `string(0) ""` 54 * 55 * When adding options with non-scalar values like 56 * `add_option( 'my_array', array( false, 'str', null ) )`, the returned value 57 * will be identical to the original as it is serialized before saving 58 * it in the database: 59 * 60 * array(3) { 61 * [0] => bool(false) 62 * [1] => string(3) "str" 63 * [2] => NULL 64 * } 65 * 66 * @since 1.5.0 67 * 68 * @global wpdb $wpdb WordPress database abstraction object. 69 * 70 * @param string $option Name of the option to retrieve. Expected to not be SQL-escaped. 71 * @param mixed $default_value Optional. Default value to return if the option does not exist. 72 * @return mixed Value of the option. A value of any type may be returned, including 73 * scalar (string, boolean, float, integer), null, array, object. 74 * Scalar and null values will be returned as strings as long as they originate 75 * from a database stored option value.
