file_existsChecks whether a file or directory exists
&reftitle.description;
boolfile_existsstringfilename
Checks whether a file or directory exists.
&reftitle.parameters;
filename
Path to the file or directory.
On windows, use //computername/share/filename or
\\computername\share\filename to check files on
network shares.
&reftitle.returnvalues;
Returns &true; if the file or directory specified by
filename exists; &false; otherwise.
This function will return &false; for symlinks pointing to non-existing
files.
This function returns &false; for files inaccessible due to safe mode restrictions. However these
files still can be included if
they are located in safe_mode_include_dir.
The check is done using the real UID/GID instead of the effective one.
