Parameters				  				   								    								     filename												     								      				       Path to the file or directory.				      				      				       On windows, use //computername/share/filename or				       \\computername\share\filename to check files on				       network shares.				      				     								    								   								  				 												 				  Return Values				  				   Returns TRUE if the file or directory specified by				   filename				 exists; FALSE otherwise.				  				  Note: 				   				    This function will return FALSE for symlinks pointing to non-existing				    files.				   				  				  Warning				   				    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.				   				  				  Note: 				   				    The check is done using the real UID/GID instead of the effective one.				   				  				 												 				  Examples				  				   				    Example #1 Testing whether a file exists				    								<?php$filename = '/path/to/foo.txt';if (file_exists($filename)) {    echo "The file $filename exists";} else {    echo "The file $filename does not exist";}?>												    								   				  				 												 				  Notes				  Note: The results of this 				function are cached. See clearstatcache() for 				more details.				  TipAs of PHP 5.0.0, this function				can also be used with some URL wrappers.  Refer to 				List of Supported Protocols/Wrappers for a listing of which wrappers support 				stat() family of functionality.
