If you are using fpdf, in order to be able to use line breaks you will need to use a <a href="http://www.fpdf.org/en/doc/multicell.htm" rel="noreferrer">multi-line text cell as described here</a>.

If you use this, then line breaks in your text should be interpreted and converted correctly.

Just a quick example:

<pre><code>$pdf-&gt;Multicell(0,2,"This is a multi-line text string\nNew line\nNew line"); 
</code></pre>

Here, 2 is the height of the multi-line text box. I don't know what units that's measured in or if you can just set it to 0 and ignore it. Perhaps try it with a large number if at first it doesn't work.

Your code reads 

<pre><code>$pdf-&gt;InsertText('Line one\n\nLine two');
</code></pre>

I don't know about the PDF library you're using but normally if you want \n to be interpreted as a line break you must use double quotes in PHP, e.g.

<pre><code>$pdf-&gt;InsertText("Line one\n\nLine two");
</code></pre>

blocks|key|3113158|text|我将'\n'更改为chr(10)，它起作用了：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|3113159|$pdf->MultiCell(0,5,utf8_decode($variable1+.+chr(10)+.+$variable2),1);|code-block|syntax|javascript|3113160|entityMap^0|2|4|9|7|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|D]]|E|@]|F|$]]|$1|G|3|H|5|I|7|S|8|@]|E|@]|F|$J|K]]|$1|L|3|-4|5|6|7|T|8|@]|E|@]|F|$]]]|M|$]]

You state that

<blockquote>
 2 is the height of the multi-line text box
</blockquote>

No it's not.
2 is the distance between lines of text.

I don't think there is a real way for calculating the height of the actual resulting text box, unless you use <code>GetY()</code> and then subtract the original Y value used in your <code>SetXY()</code> statement for placing the Multicell in the first place.

blocks|key|3325985|text|另一种选择是使用TCPDF::Ln()。它会在PDF中添加一行，并提供设置高度的选项。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3325986|如果换行符已经包含在您的内容中，那么MultiCell()可能是一种方法，正如其他人所提到的那样，但我发现我喜欢使用：|3325987|$pdf->Cell(0,+0,+'Line+1',+0,+0,+'C');

Another option is to use <a href="http://www.tcpdf.org/doc/code/classTCPDF.html#a00969cf629d72b3d29ee435f15906820" rel="noreferrer"><code>TCPDF::Ln()</code></a>. It adds a line to the PDF with the option to set the height. 

If the newlines are within your content already then <a href="http://www.tcpdf.org/doc/code/classTCPDF.html#aa81d4b585de305c054760ec983ed3ece" rel="noreferrer"><code>MultiCell()</code></a> is probably the way to go, as others have mentioned, but I find I like using:

<pre><code>$pdf-&gt;Cell(0, 0, 'Line 1', 0, 0, 'C');
$pdf-&gt;Ln();
$pdf-&gt;Cell(0, 0, 'Line 2', 0, 0, 'C');
</code></pre>

It confuses me that <a href="http://www.tcpdf.org/doc/code/classTCPDF.html#a33b265e5eb3e4d1d4fedfe29f8166f31" rel="noreferrer"><code>Cell()</code></a> and <a href="http://www.tcpdf.org/doc/code/classTCPDF.html#aa81d4b585de305c054760ec983ed3ece" rel="noreferrer"><code>MultiCell()</code></a> take in different arguments so I tend to stick to using <a href="http://www.tcpdf.org/doc/code/classTCPDF.html#a33b265e5eb3e4d1d4fedfe29f8166f31" rel="noreferrer"><code>Cell()</code></a> only. Also it reads like a newline character for the PDF the same as <code>\n</code> reads like a newline character in text or <code>&lt;br&gt;</code> in HTML.

blocks|key|3113135|text|我只是简单地用" “标记替换了"\n”。工作得很好。TCPDF似乎将文本呈现为HTML|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3113136|$strText+=+str_replace("\n"," ",$strText);

After having so many nightmares, I found a solution.

<pre><code>utf8_decode(chr(10))
</code></pre>

I tried <code>\n</code>, <code>&lt;br/&gt;</code> and <code>chr(10)</code> but nothing worked. Then I realized that it was <code>utf-8</code> and just tried the above one. It works fine with <code>MultiCell</code> but not with <code>Cell</code>.

You can configure the <code>MultiCell</code> to read html on a basic level.

blocks|key|341829|text|我找到的解决方案是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|341830|$text+=+'Line+one\n\nLine+two');
$text+=+explode('\n',+$text);

foreach+($text+as+$txt){

The solution I've found was:

<pre><code>$text = 'Line one\n\nLine two');
$text = explode('\n', $text);

foreach ($text as $txt){
 $pdf-&gt;Write($txt);
 $pdf-&gt;Ln();
}

So this way, you may have any number of \n in any position, if you're getting this text dinamically from the database, it will break lines correctrly.

In every Column, before you set the X Position indicate first the Y position, so it became like this

Column 1

<pre><code>$pdf-&gt;SetY($Y_Fields_Name_position);
$pdf-&gt;SetX(#);
$pdf-&gt;MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);

Another solutions (works with TCPDF)

Use HEREDOC for a long string. Put HERDOC for a CONST for example (define different languages) 

<pre><code>$_prepare_const_EN = &lt;&lt;&lt;EOT
this is a long string
and new line as well ...
EOT;

$define('STR_EN', $_prepare_const_EN);

$pdf-&gt;InsertText(STR_EN);

So it prints:

<blockquote>
 Line one
 
 Line two

I know <code>\n</code> doesn't work on PDF, but do you guys know any character or something that represents a line break on these files?

Inserting line breaks into PDF
