regular expression

[leon_zilber]

Hi,

I am having a problem with my regular expression:

the following input is permitted:

string
string-string
string1
string-string1
string'string

for some reason my RE wouldn't do it for me;
(ereg ("^{[a-zA-Z]?[-']*[} a-zA-Z0-9]$" , $name)

Could anyone tell me whats wrong with my expression?

Thanks a lot,
Leon

Try this.

function validate($name)
{
echo (ereg ("^{[a-zA-Z][-'][} a-zA-Z0-9]+$" , $name) ? "OK" : "BAD") . "<br>";
}

validate("string");
validate("string-string");
validate("string1");
validate("string-string1");
validate("string'string");

preg_match("/^{[\w\d]+[-']?[\w\d]*$/",} $name);
