Php替换和concat

Question

我需要在随机字符串中替换和连接一些值,我将值存储在数组中.

即

$search = array('dog', 'tree', 'forest', 'grass');
$randomString = "A dog in a forest";

如果一个或多个数组值与随机字符串匹配,那么我需要像这样的替换:

$replacedString = "A @dog in a @forest";

有人能帮我吗？

谢谢.

Answer 1

foreach (explode(' ', $randomString) as $word) {
  $replacedString .= in_array($word, $search) ? "@$word " : "$word ";
}

echo $replacedString;  // A @dog in a @forest
