Rel2Abs

string
Rel2Abs(
string cur_dir,
string rel_path
);

The function returns path relative to the specified cur_dir directory. If rel_path is empty, the function returns false. If rel_path is the absolute path (i. e. starts from "/" or has the "C:\" type), the cur_dir parameter is ignored. If a pull up of the rel_path is attempted via "../" for the path to be higher than root, the function blocks this attempt by deleting all intermediary pull ups. For example: by request /test/. ./. ./test.php it returns /test/test.php.

Function parameters

ParameterDescription
cur_dir Directory relative to which the rel_path is specified.
rel_path Relative path.
