files_exists() question

[ballhogjoni]

do you have to have an absolute path to the file for this function to work or can you have http://www.example.com?

 

ex: file_exists(/absolute/path) or file_exists(http://www.example.com)

Depends on whether or not you have url wrappers enabled. In most cases (shared hosting) you will require an absolute filesystem path.

Thorpe,

 

thx, noob question: I am not familiar with the term "filesystem path", is that another term for absolute path?

use php.net for refrences ok mate..........

 

 

file_exist needs the server path..........

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
   echo "The file $filename exists";
} else {
   echo "The file $filename does not exist";
}
?>

 

 

useing headers can see if the file exist via a full external url...

 

<?php
$file = 'http://www.domain.com/somefile.jpg';
$file_headers = @get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
   $exists = false;
}
else {
   $exists = true;
}
?>

Yeah sorry, my bad. You could probably lose the filesystem part.

maybe you ought take your own medicine. file_exists() works perfectly well given a url providing the correct wrappers are installed and enabled.

redarrow, the path does not have to be absolute.

thx,

 

all that being said I have the following code that does not work. I am on shared hosting so I don't know which wrappers are on and which ones are off (is there a way to tell?).

 

$flag_image = ABSOLUTE_PATH."public_html/xxxxxx/articles/images/flags/". $myrow['flag']. ".gif";
		echo $flag_image;
		if (file_exists($flag_image)) {
			$size = getimagesize($flag_image);
			echo " <img src='" . FACS_href . "articles/images/flags/" . $myrow['flag']. ".gif' " . $size[3] . " alt=''/>";
		}

 

the script will echo the $flag_image but the script dies after that, I assume this means that file_exists is not working correctly. Any advice?

how do u set it to not be absolte then.........

 

file_exists(http://www.example.com)  << what do u enable to get the correct result......
