How to comma separate the values of an array for display
提问by JM4
I have searched the PHP.net site and originally thought of some use for the list()function but doesn't seem to accomplish the goal:
我搜索了 PHP.net 站点，最初想到了该list()函数的一些用途，但似乎没有实现目标：
I have an unknown number of values stored in a single array
我在单个数组中存储了未知数量的值
$array1 = array(1,2,3,4,5);
$array1 = array(1,2,3,4,5);
or
或者
$array1 = array(1,2,3);
$array1 = array(1,2,3);
I want to be able to echo (or print_r) the values contained within an array to screen and separated only by commas and spacing.
我希望能够回显（或print_r）包含在数组中的值进行筛选并仅用逗号和空格分隔。
For example:
例如：
the 'idea' is to have echo $array1to display:
“想法”是让 echo$array1显示：
1,2,3
1,2,3
from the second example above.
从上面的第二个例子。

You can make use of list()function if you know there are only 3 values.
list()如果您知道只有 3 个值，则可以使用函数。
$array = array('Life', 'living', 'Health');
list($life, $living, $health) = $array;
echo $life;
echo $living;
echo $health;
Note - you can make use of implodefunction as well.
注意 - 您也可以使用implode函数。
