It _is_ correct. [^] means that whatever is in the [] must not be in the
checked var to be true! Look in "mastering regular expressions" if Youīre in
doubt. Thereīs an example [^1-6] meaning if a digit between 1 and 6 is not in
the value checked, itīs true:
$var1 = "123";
$var2 = "789";
if(ereg("[^1-6]", $var1))
print "$var1 is true";
else
print "$var1 is false";
returns false
if(ereg("[^1-6]", $var2))
print "$var2 is true";
else
print "$var2 is false";
returns true
Itīs untested though :-)
