我怎样才能使变量中的所有数组值[重复]

Question

我想将所有数组值放在一个变量中

示例：

我有一个标题

$title = "my name is medo";
$words = explode(' ', $title);

结果是

$words['0'] = my
$words['1'] = name 
$words['2'] = is 
$words['3'] = medo

我想变成那样

$allwords = "my,name,is,medo";

谢谢大家

Answer 1

你可以使用implode:

implode ( "," , $words );

Answer 2

您也可以使用字符串函数来执行此操作，这对您的情况来说更容易。

$originalString = "my name is medo";
$finalString = str_replace(" ", ",", $originalString);
