我想把字符串的最后三个单词带到它的开头。例如,这两个变量:
$vari1 = "It is a wonderful goodbye letter that ultimately had a happy ending.";
$vari2 = "The Science Museum in London is a free museum packed with interactive exhibits.";
应该成为:
"A happy ending - It is a wonderful goodbye letter that ultimately had."
"With interactive exhibits - The Science Museum in London is a free museum packed."

爆炸,重新排列,然后爆炸应该有效。请参阅示例here
$array = explode(" ", substr($input_string,0,-1));
array_push($array, "-");
for($i=0;$i<4;$i++)
array_unshift($array, array_pop($array));
$output_string = ucfirst(implode(" ", $array)) . ".";

$split = explode(" ",$vari1);
$last = array_pop($split);
$last = preg_replace("/\W$/","",$last);
$sec = array_pop($split);
$first = array_pop($split);
$new = implode(" ",array(ucfirst($first),$sec,$last)) . " - " . implode(" ",$split) . ".";
或类似的应该做的伎俩。

这将为您提供所需的完全相同的输出,只需2行代码
$array = explode(' ', $vari1);
echo ucfirst(str_replace('.', ' - ', join(' ', array_merge(array_reverse(array(array_pop($array), array_pop($array), array_pop($array))), $array)))) . '.';
