ereg problem

[Anon]

hi,

---------my script-----
while ($file_name = readdir($dir2)) {
if (($file_name!=\".\" && $file_name!=\"..\" && $file_name!=\"head.jpg\")) {
$files[]=$file_name;

}

---

I wanna exclude head.jpg, so i type $file_name!=\"head.jpg\". Also, i wanna excluse everything that starts with tn_*.jpg

I tried this
$file_name!=ereg(\"tn_*\",$trashed,$file_name), but it didn\'t work.

Please help me. Thanks

ereg() returns TRUE or FALSE, and requires a valid pattern.

if (ereg("^tn", $file_name))
{
echo $file_name." starts with tn";
};

the ^ in the pattern matches the beginning of the string.
That means that the filename must start with 'tn_'

so, will this work?
while ($file_name = readdir($dir2)) {
if (($file_name!="." && $file_name!=".." && $file_name!="head.jpg" && !ereg("^tn_", $file_name))) {
$files[]=$file_name;

}

}

it still prints whatever starts with "tn_"

First, always use parenthesis.
It doesn't take much performance, but it makes the statement a lot clearer:
if ((($file_name!=".") && ($file_name!="..") && ($file_name!="head.jpg") && (!ereg("^tn_", $file_name))))

Second, what exactly is in $file_name?
When I test it with "tn_hello.jpg" it correctly evaluates to false...

$file_name is an array which holds all files. So, i can do this $file_name[1]

thx for ur help

strange. It still prints those files. I was testing it under Red Hat linux
