This function is similar to strcasecmp(), with the difference that you can specify the (upper limit of the) number of characters from each string to be used in the comparison. Parameters

i assume you can also use the ! (not) operator <?php if (!strncasecmp($string, 'Trudeau', 4)){ print "true"; } ?> since booleans in PHP translate 0 to FALSE and any other integer to TRUE. !0 = !false = true !1 = !true = false !-1 = !true = false djdykes
Hi all, be aware when comparing strings using the strcmp family. if you write code like this... if (strncasecmp($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 |
