Hi all,
be aware when comparing strings using the strcmp family. if you write code like this...
if (strncasecmp($string, 'Trudeau', 4))
print "true";
The above code returns 1 which evaluates to boolean 'true'
that statement will always be true... because these functions return 0 only when equal. so a better
test would be
if ( (strncasecmp($string, 'Trudeau', 4)) == 0)
print "true";
always test these functions equality with 0
regards
