pathinfo
pathinfo returns information about path: either an associative array or a string, depending on flags.
Note:
For information on retrieving the current path info, read the section on predefined reserved variables.
Note:
pathinfo operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".
Caution:
pathinfo is locale aware, so for it to parse a path containing multibyte characters correctly, the matching locale must be set using the setlocale function.
Parameters
- path
-
The path to be parsed.
- flags
-
If present, specifies a specific element to be returned; one of PATHINFO_DIRNAME, PATHINFO_BASENAME, PATHINFO_EXTENSION or PATHINFO_FILENAME.
If flags is not specified, returns all available elements.
Return Values
If the flags parameter is not passed, an associative array containing the following elements is returned: dirname, basename, extension (if any), and filename.
Note:
If the path has more than one extension, PATHINFO_EXTENSION returns only the last one and PATHINFO_FILENAME only strips the last one. (see first example below).
Note:
If the path does not have an extension, no extension element will be returned (see second example below).
Note:
If the basename of the path starts with a dot, the following characters are interpreted as extension, and the filename is empty (see third example below).
If flags is present, returns a string containing the requested element.
