Php file directory current

See Also basename - Returns trailing name component of path pathinfo - Returns information about a file path realpath - Returns canonicalized absolute pathname.

As of PHP 5. Since the paths in the examples given only have two parts e. From experimentation it appears to be the latter. In short this seems to be more of a string manipulation function that strips off the last non-null file or directory element off of a path string. I ran into this when I wrote a site on a url with a path, www. Attention with this. Dirname likes to mess with the slashes. Inside of script. Expanding on Anonymous' comment, this is not necessarily correct.

If the user is using a secure protocol, this URL is inaccurate. A simple way to show the www path to a folder containing a file A key problem to hierarchical include trees is that PHP processes include paths relative to the original file, not the current including file. If an error occurs while opening the directory, the opendir function returns false.

Each directory may contain a list of files or sub-directories. It may also contain the dot entry. To get the next entry a file or a directory in a directory, you pass the directory handle to the readdir function.

Note that the readdir function returns the directories and files of the current directory specified by the directory handle.

The following code is functionally equivalent to the above example except that it uses the try By default, the current directory is the directory that contains the currently running script file. The current directory is important because it is used as the base directory for relative file paths. I know of two relatively simple ways to do this; one using dirname and one using realpath. If you are using PHP 7. This function will return the parent directory of whatever path we pass to it.

In PHP 7 and above we can specify how many levels we would like to move. To use this we first pass the file or directory path as a string, and then specify how many levels we would like to move up from that directory. If we are going back even further than PHP 5.
