PHP realizes string flipping (including Chinese characters) php randomly generates strings php gets the string length php string ratio

".str_rev_gb($str1)."
"; echo$str2."->".str_rev_gb($str2)."
"; echo$str3."->".str_rev_gb($str3)."
"; echo$str4."->".str_rev_gb($str4)."
";

=0; $i--){ $result .= mb_substr($str,$i,1,$encoding); } return$result; } $string = 'OK你是正确的Ole'; echo getRev($string); ?>

The above introduces the implementation of string flipping in PHP (including Chinese characters), including string and PHP content. I hope it will be helpful to friends who are interested in PHP tutorials.
