当包含 book.php 时，我得到一个看起来很奇怪的换行符：
echo'<div id="list-book">';
//here's where the linebreak appears
include('book.php');
echo'</div>';
在 FF firebug 中，换行符是可见的，当单击按退格键时，它会消失，并且在源代码中它根本不显示
<div id="list-book">
//here's where the linebreak appears
<?php include('book.php'); ?>
</div>
book.php 像这样开始：
<?php
//include
include($_SERVER['DOCUMENT_ROOT'] . '/config.php');
...
第一个输出是：
echo'<table id="table" class="list" cellspacing="0">'
奇怪（对我来说至少:)）是当 book.php 通过 js ajax 加载更新时填充
I get a strange looking linebreak when including book.php:
echo'<div id="list-book">';
//here's where the linebreak appears
include('book.php');
echo'</div>';
In FF firebug the linebreak is visible and when clicking pressing backspace it dissapears and in source code it does not show at all <div id="list-book"><table id="table-book" class="list" cellspacing="0"> (if that info helps). I also tried this which also gives a strange linebreak but that looks like 4 tabs (in FF firebug):
<div id="list-book">
//here's where the linebreak appears
<?php include('book.php'); ?>
</div>
book.php starts like this:
<?php
//include
include($_SERVER['DOCUMENT_ROOT'] . '/config.php');
...
and the first output is:
echo'<table id="table" class="list" cellspacing="0">'
Strange (to me at least :)) is that when the book.php gets updated via js ajax load that populate the <div id="list-book">the linebreak disappears.

您始终可以调用/滥用“标头”函数来生成错误，告诉您输出首先从哪里开始。
You could always call/abuse the "header" function to generate an error telling you where output was first started.
