PHP, add a newline with implode
提问by user1708580
I'm trying to add a newline \n, in my foreach statement with implode.
我正在尝试\n在我的 foreach 语句中添加一个换行符。
My code:
我的代码：
$ga->requestReportData($profileId,array('country'),array('visits'));
$array = array();
foreach($ga->getResults() as $result){
$array[] = "['".$result->getcountry()."', ".$result->getVisits()."]";
}
echo implode(",\n", $array);
I only get a comma and a space between my results. I want a comma and a newline.
我的结果之间只有一个逗号和一个空格。我想要一个逗号和一个换行符。
I am trying to get something like this:
我想得到这样的东西：
['Country', 'number'],
['Country', 'number'],
['Country', 'number']
['国家'，'数量']，
['国家'，'数量']，
['国家'，'数量']
However I I get this:
但是我得到了这个：
['Country', 'number'], ['Country', 'number'], ['Country', 'number']
['国家'，'数字']，['国家'，'数字']，['国家'，'数字']
Why does my \n not cause a newline?
为什么我的 \n 不会导致换行？

I suspect it is because you are echoing the data to the browser and it's not showing the line break as you expect. If you wrap your implode in the the <pre>tags, you can see it is working properly.
我怀疑这是因为您将数据回显到浏览器，并且没有按预期显示换行符。如果您将内爆包裹在<pre>标签中，您可以看到它工作正常。
Additionally, your arguments are backwards on your implodefunction, according to current documentation. However, for historical reasons, parameters can be in either order.
此外，根据当前文档，您的参数在您的内爆函数上是倒退的。但是，由于历史原因，参数可以按任意顺序排列。
$array = array('this','is','an','array');
echo "<pre>".implode(",\n",$array)."</pre>";
Output:
输出：
this,
is,
an,
array

For cross-platform-compatibility use PHP_EOLinstead of \n.
对于跨平台兼容性使用PHP_EOL而不是\n.
Using the example from the accepted answer above:
使用上面接受的答案中的示例：
$array = array('this','is','another','way');
echo "<pre>".implode(PHP_EOL, $array)."</pre>";
If you're writing directly to HTML (it wouldn't work on files) there is an option of using <br>like this:
如果您直接写入 HTML（它不适用于文件），则可以使用<br>以下选项：
$array = array('this','is','another','way');
echo "<p>".implode(<br>, $array)."</p>";
Both output:
两个输出：
this,
is,
another,
way

This can also work
这也可以工作
$array = array('one','two','three','four');
echo implode("<br>", $array);
Output:
输出：
one
two
three
four

Many others claim you use the wrong order, that's only partial right, because the docs only recommend this, but you don't have to:
许多其他人声称您使用了错误的顺序，这只是部分正确，因为文档只推荐了这一点，但您不必：
implode() can, for historical reasons, accept its parameters in either order. For consistency with explode(), however, it may be less confusing to use the documented order of arguments.
由于历史原因，implode() 可以按任一顺序接受其参数。然而，为了与explode() 保持一致，使用记录的参数顺序可能不会那么混乱。
I think your problem is caused by how browsers interpret HTML. They don't care about newlines, they're like a normal space for them.
我认为您的问题是由浏览器如何解释 HTML 引起的。他们不关心换行符，他们就像一个普通的空间。
To show these linebreaks, you can use <pre><?php echo implode($glue, $array); ?></pre>. You could also use nl2br(implode(..))or nl2br(implode(..), true)if you're writing XHTML.
要显示这些换行符，您可以使用<pre><?php echo implode($glue, $array); ?></pre>. 您也可以使用nl2br(implode(..))ornl2br(implode(..), true)如果您正在编写 XHTML。
