PHP SMWDIProperty::findPropertyID方法代码示例

 /**
  * Construct a property from a user-supplied label. The main difference
  * to the normal constructor of SMWDIProperty is that it is checked
  * whether the label refers to a known predefined property.
  * Note that this function only gives access to the registry data that
  * SMWDIProperty stores, but does not do further parsing of user input.
  * For example, '-' as first character is not interpreted for inverting
  * a property. Likewise, no normalization of title strings is done. To
  * process wiki input, SMWPropertyValue should be used.
  *
  * @param $label string label for the property
  * @param $inverse boolean states if the inverse of the property is constructed
  *
  * @return SMWDIProperty object
  */

 /**
  * Normalize the information for an SMW object (page etc.) and return
  * the predefined ID if any. All parameters are call-by-reference and
  * will be changed to perform any kind of built-in normalization that
  * SMW requires. This mainly applies to predefined properties that
  * should always use their property key as a title, have fixed
  * sortkeys, etc. Some very special properties also have fixed IDs that
  * do not require any DB lookups. In such cases, the method returns
  * this ID; otherwise it returns 0.
  *
  * @note This function could be extended to account for further kinds
  * of normalization and predefined ID. However, both getSMWPropertyID
  * and makeSMWPropertyID must then also be adjusted to do the same.
