Hi List, my research hasn't turned anything useful up. Probably 'cause I don't have enough info. I've been playing around with the ereg function. What I was wondering is what is the ^ for like in the below example?
    ereg('[^[:space:]a-zA-Z0-9_.-]{1,}', $name)
thx janbro
it denotes the "start of the string"
Actually, in the above case it doesn't... from the URL referenced...
    For example, the character class [aeiou] matches any lower case vowel,
    while [^aeiou] matches any character that is not a lower case vowel.
If the ^ is outside of the []'s then it matches the start of the string... -philip

hey, you're right ;) must've missed the opening [ there. Well spotted!
