file_exists

(PHP3 , PHP4 )

file_exists -- Check whether a file exists

Description

int file_exists (string filename)

Returns true if the file specified by filename exists; false otherwise.

file_exists() will not work on remote files; the file to be examined must be accessible via the server's filesystem.

The results of this function are cached. See clearstatcache() for more details.

the description of this function should read:

bool file_exists(string filename);

Also, ich habe jetzt verstanden, dass man mit diesem Befehl keine URL ueberpruefen kann. Aber ich suche einen genau solchen Befehl fuer eine Suchmaschine. Gibt es so etwas - Bitte e-mail an mich, wenn jemand etwas weiss !

My limited knowledge of German combined with my limited knowledge of English, anyhow, I have the same question:
Is there a function to check is a given URL exists. I tried this one, but nope...

Use fopen function to check if a given URL exists. See note added by
chopin@csone.kaist.ac.kr within documentation for fopen for an example.

file_exists does not traverse the include path.

file_exists() also works with directory names - use this instead of is_dir() and is_file() to verify something's existence.

Does php provide a function that supports globbing like
file_exists("f*")? I'm pretty sure it doesn't.

How do I create a blank txt file though? I want to have file_exists chekc for a file and if it doesn't exits, then I want that file created.

<pre>
if (!file_exists($file) {
$fp = fopen("temp.phtml", "w");
fputs($fp, $entry);
fclose($fp);
copy("temp.phtml", $catgr . "/" . $newfile);
chmod($catgr . "/" . $newfile, 0777);
</pre>
this should create a file with whatever data you want as the body. I've found that sometime the file permission are off, so i'd have to open an empty file which i leave on the server, then copy that file to the newfile, using chmod to set the permission so i can edit it later.

is there a way to get a list of files in a directory? (ls) I want to delete any files that aren't in a given database.

yeah, there's a beautiful way to get the content of a directory (files, dirs etc.)
this is a PHP xommand: readdir();
code example is:
&lt;?
$handle=opendir('.');
echo "files:"; echo "
";
while ($file = readdir($handle)) {
echo "$file"; echo "
";
}
?>
