hi, everbody....
i've got stuck on this regex.
<?
$teks="teks123";
$pattern="^[a-zA-Z]";

if(eregi($pattern,$teks))
{
echo "Teks is valid>";
}
else
{
echo "Teks isn't valid.";
}
?>

my question is : i want to filter only for charcter. But, when i run that script, i've got : Teks is valid. :wacko:
i want that '$teks' can't come in into my aplications.
Pliz, help and correct me.....

$pattern="^[a-zA-Z]$";

^ means beginning of string
$ means end of string
So: starts with [a-zA-Z] and ends with [a-zA-Z]

Not to be picky or anything, but that actually means everything from start to finish is only [a-zA-Z]. Not just the first and last characters. Also, since you're using eregi, as opposed to ereg, you don't need the capital letters.

I'd love to offer some actual help, but i don't understand what you mean by "come in."

i mean, i a run that script i've got "Teks isn't valid". Coz that teks combine with charcter and number. I want only $teks contain with charcter can be "come in".
i'm sorry, my english very bad

thanx b4...

Sorry rc69, that's what I meant to say - just came out all wrong

$pattern = "^come in$";

Try that
