php - PHP在每个新单词的末尾添加字符

Question

我有一串用空格分隔的单词（最后一个单词除外），我想知道是否有办法在每个新单词的末尾添加一个字符。例如：

$string = "this is a short string of words"

会成为

$string = "this; is; a; short; string; of; words;"

谢谢

Answer 1

$str = 'lorem ipsum';  
$str_modified = str_replace(' ','; ',trim($str)).';';

Answer 2

爆炸和内爆：

implode("; ", explode(" ", $string)).";"; 

Answer 3

你可以preg_replace()这样使用：

$string = "this is a short string of words";
echo preg_replace('~(\w+)~', '$1;',$string);

// output: this; is; a; short; string; of; words;
