realpath Returns canonicalized absolute pathname &reftitle.description; stringrealpath stringpath realpath expands all symbolic links and resolves references to /./, /../ and extra / characters in the input path and returns the canonicalized absolute pathname. &reftitle.parameters; path The path being checked. Whilst a path must be supplied, the value can be an empty string. In this case, the value is interpreted as the current directory. &reftitle.returnvalues; Returns the canonicalized absolute pathname on success. The resulting path will have no symbolic link, /./ or /../ components. Trailing delimiters, such as \ and /, are also removed. realpath returns &false; on failure, e.g. if the file does not exist. The running script must have executable permissions on all directories in the hierarchy, otherwise realpath will return &false;. For case-insensitive filesystems realpath may or may not normalize the character case. The function realpath will not work for a file which is inside a Phar as such path would be a virtual path, not a real one. &fs.file.32bit; &reftitle.changelog; &Version; &Description; 5.3.0 Prior to this release, if only the last path component did not exist, realpath would not fail on *BSD systems. realpath now fails in this case. 5.2.1 Prior to this version, realpath returned &false; if path is an empty string or &null;. &reftitle.examples; ]]> &example.outputs; On windows realpath will change unix style paths to windows style. ]]> &example.outputs; &reftitle.seealso; basename dirname pathinfo
