如何在变量中创建所有数组值

Question

我想在一个变量

中创建所有数组值

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

我想这样做

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

感谢所有

Answer 1

您可以使用implode：

implode ( "," , $words );

Answer 2

您也可以使用字符串函数执行此操作，这对您的案例更容易。

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