PHP將字符添加到每個新單詞的末尾

Question

我有一串由空格分隔的單詞（除了最後一個單詞），我想知道是否有方法在每個新單詞的末尾添加一個字符。例如：

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

將成爲

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

感謝

Answer 1

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

Answer 2

Explode和Implode：

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

Answer 3

您可以使用preg_replace()像這樣：

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

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