<h1>Minimal example</h1>
|
||
|
|
Let's start with the classic example:
|
||
|
|
<div class="source">
|
||
|
|
<pre><code><?php
|
||
|
|
<span class="kw">require(</span><span class="str">'fpdf.php'</span><span class="kw">);
|
||
|
|
|
||
|
|
</span>$pdf<span class="kw">=new </span>FPDF<span class="kw">();
|
||
|
|
</span>$pdf<span class="kw">-></span>AddPage<span class="kw">();
|
||
|
|
</span>$pdf<span class="kw">-></span>SetFont<span class="kw">(</span><span class="str">'Arial'</span><span class="kw">,</span><span class="str">'B'</span><span class="kw">,</span>16<span class="kw">);
|
||
|
|
</span>$pdf<span class="kw">-></span>Cell<span class="kw">(</span>40<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Hello World!'</span><span class="kw">);
|
||
|
|
</span>$pdf<span class="kw">-></span>Output<span class="kw">();
|
||
|
|
</span>?></code></pre>
|
||
|
|
</div>
|
||
|
|
<p class='demo'><a href='tuto1.php' target='_blank' class='demo'>[Demo]</a></p>
|
||
|
|
After including the library file, we create an FPDF object.
|
||
|
|
The <a href='../doc/fpdf.htm'>FPDF()</a> constructor is used here with the default values: pages are in A4 portrait and
|
||
|
|
the unit of measure is millimeter. It could have been specified explicitly with:
|
||
|
|
<div class="source">
|
||
|
|
<pre><code>$pdf<span class="kw">=new </span>FPDF<span class="kw">(</span><span class="str">'P'</span><span class="kw">,</span><span class="str">'mm'</span><span class="kw">,</span><span class="str">'A4'</span><span class="kw">);
|
||
|
|
</span></code></pre>
|
||
|
|
</div>
|
||
|
|
It is possible to use landscape (<code>L</code>), other page formats (such as <code>Letter</code> and
|
||
|
|
<code>Legal</code>) and units of measure (<code>pt</code>, <code>cm</code>, <code>in</code>).
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
There is no page for the moment, so we have to add one with <a href='../doc/addpage.htm'>AddPage()</a>. The origin
|
||
|
|
is at the upper-left corner and the current position is by default placed at 1 cm from the
|
||
|
|
borders; the margins can be changed with <a href='../doc/setmargins.htm'>SetMargins()</a>.
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
Before we can print text, it is mandatory to select a font with <a href='../doc/setfont.htm'>SetFont()</a>, otherwise the
|
||
|
|
document would be invalid. We choose Arial bold 16:
|
||
|
|
<div class="source">
|
||
|
|
<pre><code>$pdf<span class="kw">-></span>SetFont<span class="kw">(</span><span class="str">'Arial'</span><span class="kw">,</span><span class="str">'B'</span><span class="kw">,</span>16<span class="kw">);
|
||
|
|
</span></code></pre>
|
||
|
|
</div>
|
||
|
|
We could have specified italics with I, underlined with U or a regular font with an empty string
|
||
|
|
(or any combination). Note that the font size is given in points, not millimeters (or another
|
||
|
|
user unit); it is the only exception. The other standard fonts are Times, Courier, Symbol and
|
||
|
|
ZapfDingbats.
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
We can now print a cell with <a href='../doc/cell.htm'>Cell()</a>. A cell is a rectangular area, possibly framed,
|
||
|
|
which contains a line of text. It is output at the current position. We specify its dimensions,
|
||
|
|
its text (centered or aligned), if borders should be drawn, and where the current position
|
||
|
|
moves after it (to the right, below or to the beginning of the next line). To add a frame, we would do this:
|
||
|
|
<div class="source">
|
||
|
|
<pre><code>$pdf<span class="kw">-></span>Cell<span class="kw">(</span>40<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Hello World !'</span><span class="kw">,</span>1<span class="kw">);
|
||
|
|
</span></code></pre>
|
||
|
|
</div>
|
||
|
|
To add a new cell next to it with centered text and go to the next line, we would do:
|
||
|
|
<div class="source">
|
||
|
|
<pre><code>$pdf<span class="kw">-></span>Cell<span class="kw">(</span>60<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Powered by FPDF.'</span><span class="kw">,</span>0<span class="kw">,</span>1<span class="kw">,</span><span class="str">'C'</span><span class="kw">);
|
||
|
|
</span></code></pre>
|
||
|
|
</div>
|
||
|
|
Remark: the line break can also be done with <a href='../doc/ln.htm'>Ln()</a>. This method additionnaly allows to specify
|
||
|
|
the height of the break.
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
Finally, the document is closed and sent to the browser with <a href='../doc/output.htm'>Output()</a>. We could have saved
|
||
|
|
it to a file by passing the desired file name.
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
<strong>Caution:</strong> in case when the PDF is sent to the browser, nothing else must be output by the
|
||
|
|
script, neither before nor after (no HTML, not even a space or a carriage return). If you send something
|
||
|
|
before, you will get the error message: "Some data has already been output, can't send PDF file". If you
|
||
|
|
send something after, the document might not display.
