根據(jù)這個(gè)思路我用PHP使用
<?php
//字符串反置
function ReverseStr (&$str, $len){
$i = 0;
for($i; $i < $len; $i++,$len--){
$ch = $str[$i];
$str[$i] = $str[$len];
$str[$len] = $ch;
}
}

function ReverseStrWord ($word, $len){

if($len == 1) return ;

//倒置全部字符串
ReverseStr(&$word, $len);

//去除字符串前的空格
$i = 0;
if($word[0] == ' ') {
while ($word[$i] == ' ' && $i < $len) {
$i++;}
}

//全是空格返回
if($i == $len) return ;

//去除尾部空格
if($word[$len] == ' ') {
while ($word[$len] == ' ' && $len > $i) {
$len--;}
}

for($start = $i; $i <= $len; $i++ ){

$str .= $word[$i];

if($i == $len){
ReverseStr($str, $i-$start+1);
$R_string .= $str;
break;
}

if($word[$i] == ' '){
ReverseStr($str, $i-$start);
$R_string .= $str;
$str = '';
$start = $i+1;
if($word[$start] == ' '){
while ($word[$start] == ' ') {
$start++;
$i++;
}
}
}
}
return $R_string;
}


$str = "Times New Roman";
$len = strlen($str);
$pstr = ReverseStrWord($str, $len);

?>
