我的數組是這樣的：

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

如何這個喜歡這個用PHP轉換爲字符串？

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

Answer 1

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

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

Answer 2

您正在尋找implode()

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

Answer 3

讓你的數組變量和使用破滅。

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

echo $comma_separated; // lastname,email,phone
