我需要使用trim（）分隔一个字符串

Question

如何分隔字符串“JavaScript和PHP非常有趣！”在PHP中使用trim（）？

每个人都必须在一个单独的行上。

他们都工作，除了“和”返回“d”和“是”返回“e”。有人可以帮忙吗？

<?php
$str12 = "JavaScript and PHP are so much fun!";
echo rtrim($str12,"and PHP are so much fun!");
echo "<br>";
echo trim($str12,"JavaScript PHP are so much fun!");
echo "<br>";
echo trim($str12,"JavaScript and are so much fun!");
echo "<br>";
echo trim($str12,"JavaScript and PHP so much fun!");
echo "<br>";
echo trim($str12,"JavaScript and PHP are much fun!");
echo "<br>";
echo trim($str12,"JavaScript and PHP are so fun!");
echo "<br>";
echo ltrim($str12,"JavaScript and PHP are so much");
?>
