How to create comma separated list from array in PHP?

我的数组看起来像这样：

Array
(
    [0] => lorem
    [1] => ipsum
    [2] => dolor
    [3] => sit
    [4] => amet
)

如何使用php将其转换为这样的字符串？

$string = 'lorem, ipsum, dolor, sit, amet';

Answer 1

$arr = array ( 0 => "lorem", 1 => "ipsum", 2 => "dolor");

$str = implode (", ", $arr);

Answer 2

直接来自docs：

$comma_separated = implode(",", $array);

Answer 3

使您的数组成为变量并使用implode。

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

echo $comma_separated; // lastname,email,phone

Answer 4

您正在寻找implode()

$string = implode(",", $array);
