Example:

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<?php ;​​​​​​​$var2= "Hello"; ,$var2 )==0) {echo'equal';                                                                                                 {                                                                                                                                                                ​             } ?> strcasecmp — Binary safe string comparison (case insensitive) ? 1 int strcasecmp(string $str1 ,string $str2 )
