PHP: Concatenate array element into string with ',' as the separator
提问by Graviton
Is there a quick way ( existing method) Concatenate array element into string with ',' as the separator? Specifically I am looking for a single line of method replacing the following routine:
有没有一种快速的方法（现有方法）将数组元素连接成以“，”为分隔符的字符串？具体来说，我正在寻找一行替换以下例程的方法：
//given ('a','b','c'), it will return 'a,b,c'
private static function ConstructArrayConcantenate($groupViewID)
{
$groupIDStr='';
foreach ($groupViewID as $key=>$value) {
$groupIDStr=$groupIDStr.$value;
if($key!=count($groupViewID)-1)
$groupIDStr=$groupIDStr.',';
}
return $groupIDStr;
}

$arr = array('a','b','c');
$str = join(',',$arr);
join is an alias for implode, however I prefer it as it makes more sense to those from a Java or Perl background (and others).
join 是 implode 的别名，但我更喜欢它，因为它对那些有 Java 或 Perl 背景（和其他人）的人更有意义。

implode() function is the best way to do this. Additionally for the shake of related topic, you can use explode() function for making an array from a text like the following:
implode() 函数是最好的方法。此外，对于相关主题的震动，您可以使用explode() 函数从文本中创建数组，如下所示：
$text = '18:09:00'; $t_array = explode(':', $text);
$text = '18:09:00'; $t_array = expand(':', $text);

You can use implode() even with empty delimeter: implode(' ', $value);pretty convenient.
即使使用空分隔符，您也可以使用 implode()：implode(' ', $value);非常方便。
