如何在PHP中使用不同的字符串生成随机帖子标题

Question

​

add_filter('syndicated_item_title', 'fwp_set_title', 10, 2);
function fwp_set_title ($title)
{
   $title1[0] = "Title 1";
   $title1[1] = "Title 2";
   $title1[2] = "Title 3";
   $title1[3] = "Title 4";
   $title1[4] = "Title 5";
   $title1[5] = "Title 6";
   $title1[6] = "Title 7";
   $title1[7] = "Title 8";
   $title1[8] = "Title 9";
   $title1[9] = "Title 10";
   $randomize = rand(0, 9);
   return ($title1[$randomize]);
}

​

下面是代码。其结果是它只能从标题1-9中选择，这是我不喜欢的。我想要的是生成一个标题，这是从标题1-5 (第一个单词)和下一个单词是从标题6-9 (第二个单词)

示例: Hello (来自标题1-5的随机单词) World (来自标题6-9的随机单词)

请帮我修改一下这个。

我想我知道你想要什么，所以希望这是正确的。

add_filter('syndicated_item_title', 'fwp_set_title', 10, 2);
function fwp_set_title ($title)
{
   $title1[0] = "Title 1";
   $title1[1] = "Title 2";
   $title1[2] = "Title 3";
   $title1[3] = "Title 4";
   $title1[4] = "Title 5";
   $title1[5] = "Title 6";
   $title1[6] = "Title 7";
   $title1[7] = "Title 8";
   $title1[8] = "Title 9";
   $title1[9] = "Title 10";
   $randomize = rand(0, 4); // randomize first 5
   $firstWord = strstr($title1[$randomize], ' ', TRUE); // get first word
   $randomize = rand(5, 9); // randomize last 5
   $secondWord = trim(strstr($title1[$randomize], ' ', FALSE)); // get second word
   echo $firstWord . $secondWord; // output
}

函数strstr查找要搜索的字符串，并返回该字符串之前或之后的所有内容。

或者使用此函数：

public static function ipsum($nparagraphs, $wrapper = 'p') {
    $paragraphs = [];
    for ($p = 0; $p < $nparagraphs; ++$p) {
        $nsentences = mt_rand(3, 8);
        $sentences = [];
        for ($s = 0; $s < $nsentences; ++$s) {
            $frags = [];
            $commaChance = .33;
            while (true) {
                $nwords = mt_rand(3, 15);
                $words = self::random_values(self::$lorem, $nwords);
                $frags[] = implode(' ', $words);
                if (self::random_float() >= $commaChance) {
                    break;
                }
                $commaChance /= 2;
            }

            $sentences[] = ucfirst(implode(', ', $frags)) . '.';
        }
        $paragraphs[] = '<' . $wrapper . '>' . implode(' ', $sentences) . '</' . $wrapper . '>';
    }
    return implode($paragraphs);
}

private static function random_float() {
    return mt_rand(0, PHP_INT_MAX - 1) / PHP_INT_MAX;
}

private static function random_values($arr, $count) {
    $keys = array_rand($arr, $count);
    if ($count == 1) {
        $keys = [$keys];
    }
    return array_intersect_key($arr, array_fill_keys($keys, null));
}

private static $lorem = [
