Reg Exp Depression

[Anon]

Hi I apologise for yet another Reg Exp question...... but I'm totally lost.

I want to create 3 reg expressions (or another solution) for each of the following:

1) Take a variable and check it ONLY contains Numbers.

2) Take a variable and check it only contains letters.

3) Take a variable and check it only contains numbers and/or letters.

Thank you for reading 🙂

1. eregi('[0-9]', $yourVar);
   OR
   eregi('[[:digit:]]', $yourVar);

2. eregi('[A-Z]', $yourVar);
   OR
   eregi('[[:alpha:]]', $yourVar);

3. eregi('[A-Z0-9]', $yourVar);
   OR
   eregi('[[:alnum:]]', $yourVar);

for more info on furhter eregi() or ereg() arguments, see www.php.net/manual

good luck,
Daarius...

Thank you most kidnly Daarius for your help, I'm sure this is correct but they didnt work for me.

I'm using php4 / apache / win 98 - for anyone who is after similar information the following works for me (but i might wanna try Daarius from the previous message first)

ereg("^{[[:alpha:]]+$",} $value);

ereg("^{[[:digit:]]+$",} $value);

ereg("^{[[:alnum:]]+$",} $value);

Once again, thank you 🙂
