Question

我有一个字符串，其中可能使用多种语言，例如：

این متن فارسی است and this is !!! in English
این خط بعدی است و this is going to be continued...

我只想反向翻译英文单词，所以结果应该像这样：

این متن فارسی است English in !!! is this and
این خط بعدی است و continued be to going is this...

要使文本反转，我得到：

public static function reverseEnglishWords($string)
{
    return preg_replace_callback('/\w+/', function (array $m) { return strrev($m[0]); }, $string);
}

但是它会反转所有字符。

编辑：这是目前最有效的方法：

<?php
$string = "
این یک تست جدید است
Is my English line working just fine?
I hope it does...
این یک جمله جدید است and this is to be continued in English...
";

$newStr = preg_replace_callback('/\w.*(?=\w|\b)/', function (array $m) { 
    return implode(" ", array_reverse(explode(" ", $m[0])));
}, $string);

echo $newStr;

唯一的问题是字符串的enf中有一些字符，例如?和...在上面的示例中放错了位置。当前结果是：

این یک تست جدید است fine just working line English my Is? does it hope I... این یک جمله جدید است English in continued be to is this and...

应为：

این یک تست جدید است ?fine just working line English my Is ...does it hope I این یک جمله جدید است ...English in continued be to is this and

Answer 1

您可以使用

function reverseEnglishWords($string)
{
    return preg_replace_callback('/(?!\s)[^\p{Arabic}\r\n]+/u', function ($m) { 
            $tmp = preg_replace_callback('~(\w+)([^\w\s]+)~', function($n) {
                return strrev($n[2]) . $n[1];
            }, $m[0]);
            return implode(" ", array_reverse(
                    preg_split('~\s+~u', $tmp, -1, PREG_SPLIT_NO_EMPTY)
                  )
            );
        }, $string);
}

$s = "
این یک تست جدید است
Is my English line working just fine?
I hope it does...
Another one?!
این یک جمله جدید است and this is to be continued in English...
";

echo reverseEnglishWords($s);

参见PHP demo，输出

این یک تست جدید است
?fine just working line English my Is
...does it hope I
!?one Another
این یک جمله جدید است ...English in continued be to is this and

在这里，/(?!\s)[^\p{Arabic}\r\n]+/u匹配一个或多个不属于阿拉伯语脚本且不属于CR和LF的连续字符（以非空白字符开头）。匹配项将传递给preg_replace_callback匿名函数，在该匿名函数中，匹配项首先与另一个preg_replace_callback处理，以反转以字母开头和标点符号结尾的单词中的字母和标点符号（请参见(\w+)([^\w\s]+) regex）然后使用任何种类的Unicode空格进行拆分，同时丢弃空项目（请参见preg_split('~\s+~u', $m[0], -1, PREG_SPLIT_NO_EMPTY)），array_reverse反转找到的“单词”数组，而implode将反转的项目与一个空格连接起来。

使用反向数组

class Book(models.Model):
    publisher = models.IntegerField()
    issue = models.CharField(max_length=255)

    class Meta:
        unique_together = ("publisher", "issue")

    def __str__(self):
        return "%s-%r" % (self.publisher,self.issue)


class Version(models.Model):
    book = models.ForeignKey(Book, on_delete = models.CASCADE)
    number = models.CharField(max_length=255)
    book_name = models.CharField(max_length=255)
    cover = models.ImageField(null=True)
    description = models.CharField(max_length=255)

    class Meta:
        unique_together = ("book", "number")

    def __str__(self):
        return "%s %s" % (self.number, self.book)




class Copy(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1, on_delete=models.CASCADE)
    version = models.ForeignKey(Version, on_delete = models.CASCADE)
    number = models.IntegerField()
    book_id = models.AutoField(primary_key=True)
    book_size = models.CharField(null=True, blank=True,max_length=255)


    def __str__(self):
        return "%r" % (self.book_id)


    class Meta:
        unique_together = ("version", "number")

Answer 3

您需要选择以英文字符开头和以英文字符结尾的字符串。然后在回调函数中使用array_reverse()

将字符串按空格和反向数组拆分

$newStr = preg_replace_callback('/\w.*(?=\w|\b)/', function (array $m) { 
    return implode(" ", array_reverse(explode(" ", $m[0])));
}, $string);

在demo中查看结果

尝试一下：

<?php

function reverseSentence($string)
{
    $array = explode(" ", $string);
    $rarray = array_reverse($array);
    $reversed = implode(" ", $rarray);
    return $reversed;
}

function reverseEnglishWords($string)
{
    return preg_replace_callback('/[\s\w\d]*/', function($m) {
        return reverseSentence($m[0]);
    } , $string);
}

$s = "این متن فارسی است and this is !!! in English";
echo reverseEnglishWords($s);

输出：

> $ php example.php
این متن فارسی است is this and !!!English in
