PHP随机搜索和替换字符串

Question

我有以下两个变量/字符串：

$article = ('Perfume is a mixture of fragrant word1 and aroma complexes, which can be applied to the human body, animals, word2, objects, and living spaces in order to give off a pleasant word3.');

$words = '{word1|word2|word3|word4|word5}';

我需要做的是搜索$ article中$ word中的任何单词，如果发现随机替换$ article中的单词，则从$ word中随机选取单词。

我该怎么办呢？

Answer 1

如果您需要以相同的格式保留所有内容;

$article = ('Perfume is a mixture of fragrant word1 and aroma complexes, which can be applied to the human body, animals, word2, objects, and living spaces in order to give off a pleasant word3.');
$words = '{word1|word2|word3|word4|word5}';

$words = explode('|', str_replace(array('{', '}'), '', $words));

echo str_replace($words, $words[array_rand($words)], $article);

Answer 2

创建一个$ words数组。获取数组的随机键，并使用随机选择的单词str_replace $ article。

$words = array('word1', 'word2', 'word3', 'word4');
$randkeyA = array_rand($words);
$randkeyB = array_rand($words);
echo str_replace($words[$randkeyA], $words[$randkeyB], $article);
