随机字符串旋转问题

Question

我想要做一个自旋函数来旋转一个字符串，但是我为它的实现寻找了一个问题。我知道如何在字符串中弹奏单词，比如改变{hi\hello}，但我想要的是不同的，它是在字符串中旋转的

$spin_words=array('Word1','Word2','Word3');
$text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry.";

所以我想随机添加一些单词，比如

Lorem是印刷和排版行业的Word1虚拟文本。

或

Lorem只是印刷、、Word2、和排版行业的虚拟文本。

或

Lorem只是印刷和排版行业Word3的虚拟文本。

所以任何帮助的人

问候

Answer 1

你可以试试

$words = array('Word1','Word2','Word3');
$text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry.";
echo wordInString($text,$words);
echo wordInString($text,$words);

输出示例

Lorem Ipsum is simply dummy Word1 text of the printing and typesetting industry.
Lorem Ipsum is simply dummy text of the printing Word2 and typesetting industry.

所用功能

function wordInString($text,array $words) {
    $textNew = array();
    $p = mt_rand(0, substr_count($text, " "));
    $tok = strtok($text, " \n\t");
    $x = 1;
    while ( $tok !== false ) {
        $textNew[] = $tok and $x == $p and $textNew[] = $words[array_rand($words, 1)];
        $tok = strtok(" ");
        $x ++;
    }
    return implode(" ", $textNew);
}
