从 foreach 循环中删除最后一个逗号 [英] Removing last comma from a foreach loop

问题描述

我使用 foreach 循环从我的数据库中回显一些值并用逗号分隔每个值，但我不知道如何删除它在最后一个值上添加的最后一个逗号.

Im using a foreach loop to echo out some values from my database and seperating each of them by commas but I dont know how to remove the last comma it adds on the last value.

我的代码很简单，但我似乎无法找到正确的方法:

My code is pretty simple but I just cant seem to find the correct way of doing this:

foreach ($this->sinonimo as $s){ 

echo '<span>'.ucfirst($s->sinonimo).',</span>';

}

在此先感谢您的帮助:)

Thanks in advance for any help :)

推荐答案

把你的值放在一个数组中，然后用逗号(+ 一个空格更干净)implode 该数组:

Put your values in an array and then implode that array with a comma (+ a space to be cleaner):

$myArray = array();
foreach ($this->sinonimo as $s){ 
    $myArray[] = '<span>'.ucfirst($s->sinonimo).'</span>';
}

echo implode( ', ', $myArray );

这会将逗号放在每个值之间，但不会放在末尾.同样在这种情况下，逗号将在跨度之外，例如:

This will put commas inbetween each value, but not at the end. Also in this case the comma will be outside the span, like:

<span>Text1<span>, <span>Text2<span>, <span>Text3<span>
