searching a dir for a file

[Anon]

I have a directory called 'profiles'

inside the directory i have individual username files eg. username.dat

Where username will be that persons username.

Now I want to be able to check if that person's file is there and report an error if not and if it is, run my function.

Can someone write me a code for that.

the username will be picked from a query string.. eg..
?user=USER_NAME
so then $user will equal USER_NAME
Then change it into a file name USER_NAME.dat

$filename = "$user.dat";

function is_file_present($user) {
$dir = dir("pathtouserfiles/");
while ($file = $dir->read()) {
if ($file == $user.".dat") {
$found = 1;
}
}
return $found;
}

//Sample usage
if (is_file_present($user)) {
print "File found";
}
else {
print "File not found";
}

Hi

Even though I'm very new to PHP, it seems easier to use the built-in file_exists. One way could ne:

if (file_exists(path/filename)){
do your thing;
}
else {
throw the error;
}
