php - php(?) 在大字符串上插入一个空格

Question

我有一个很大的表单，可以将包含其内容的电子邮件发送给站点管理员。我遇到的问题是在某些时候插入了一个空格，这会导致标记问题。发送的电子邮件是 HTML 电子邮件，有时会在标签之间插入随机空格字符，因此<li>我得到的不是< li>. 这是一个问题，因为列表项确实会被呈现为列表项，而是呈现为包含< li>标签的普通文本。

我至少有一次注意到这种行为。有一次，当我在论坛上发帖时，在我输入的单词中间添加了一个空格。奇怪的是，这个词是岳母，（西班牙语中的苏格拉）。当时很好笑，因为我第一次教的是，由于婆婆名声不好，管理员开了个玩笑，但这一次不好笑。这次这个问题真的是个问题，因为标记都搞砸了。

有谁知道为什么要添加空格？似乎是随机的。但是，如果我从表单上的一个字段中删除一个字符，则似乎没有添加空格，或者它可能是在不同的位置添加的，比如就在<< 和 li 之间而不是在 < 和 li 之间标记。此外，如果我只是回显应该在电子邮件中发送的消息，则在电子邮件中添加它的位置的字符串中没有空格。

编辑这是相关的代码。它很大，但大部分只是构造一个字符串：

我认为最有可能的情况是线路由于太长而被打破。

尝试\n在其中插入一些，最好在每个之后插入<li>以保持合理的行长。
