* Also, this function provides conversion between path types, in this case the input path points inside the Chamilo area too.
|
|
*
|
|
* See $_configuration['course_folder'] in the configuration.php to alter the WEB_COURSE_PATH and SYS_COURSE_PATH parameters.
|
|
|
|
*
|
|
* @param string $path (optional) A path which type is to be converted. Also, it may be a defined constant for a path.
|
|
* This parameter has meaning when $type parameter has one of the following values: TO_WEB, TO_SYS, TO_REL. Otherwise it is ignored.
|
|
*
|
|
* @return string the requested path or the converted path
|
|
*
|
|
* Notes about the current behaviour model:
|
|
* 1. Windows back-slashes are converted to slashes in the result.
|
|
* 2. A semi-absolute web-path is detected by its leading slash. On Linux systems, absolute system paths start with
|
|
* a slash too, so an additional check about presence of leading system server base is implemented. For example, the function is
|
|
* able to distinguish type difference between /var/www/chamilo/courses/ (SYS) and /chamilo/courses/ (REL).
|
|
* 3. The function api_get_path() returns only these three types of paths, which in some sense are absolute. The function has
|
|
* no a mechanism for processing relative web/system paths, such as: lesson01.html, ./lesson01.html, ../css/my_styles.css.
|
|
* It has not been identified as needed yet.
|
|
* 4. Also, resolving the meta-symbols "." and ".." within paths has not been implemented, it is to be identified as needed.
|
|
*
|
|
* For examples go to: *
|
|
* See main/admin/system_status.php?section=paths
|
|
*
|
|
* Vchamilo changes : allow using an alternate configuration
|
|
* to get vchamilo instance paths
