The class used today is called Fpdf,fpdf this PHP class allows you to use pure PHP (rather than using pdflib) to generate PDF files. It shows up in PHP class and accelerates the process of PDF documents in the programming language. Its features include: selectable cell size, page formatting and margins, header and footer management, automatic pagination, automatic line wrapping and text alignment, and so on. It also supports a variety of image formats, such as Jpeg,png,truetype and Type1, among others. You will not be disappointed with a trial.
1, download fpdf from the Internet class, and then practical require included (also in the attachment).
Copy Code code as follows:
Require ('./fpdf/fpdf.php ');//include PDF file
2, and then we define an array, and the contents of the array is today's medal situation
Copy Code code as follows:
/*
* Country, National
* Nationalflag, Flag
* Glod, number of gold medals
* Silver, number of silver medals
* Copper, number of silver medals
*/
$platle =array (
Array (' Country ' => ' PRC ', ' nationalflag ' => ' rpc.jpg ', ' Glod ' =>27, ' Silver ' =>13, ' copper ' =>15),
Array (' Country ' => ' USA ', ' nationalflag ' => ' usa.jpg ', ' Glod ' =>25, ' Silver ' =>16, ' copper ' =>4),
Array (' Country ' => ' UK ', ' nationalflag ' => ' uk.jpg ', ' Glod ' =>14, ' Silver ' =>7, ' copper ' =>8)
);
3, since the first step has been included in the class, and then we define a class to facilitate the definition of their own content
Copy Code code as follows:
Class PDF extends fpdf{
/*
* $count, National
* $nationalFlag, the picture address of the national flag
* $imageX, the x-coordinate of the flag
* $imageY, the y-coordinate of the flag
* $goldTotal, total number of gold medals
* $silverTotal, Total silver
* $copperTotal, Total bronze
*/
function Createhead ($country, $nationalFlag, $imageX, $imageY, $goldTotal, $silverTotal, $copperTotal) {
$this->setfont (' Arial ', ' B ', ' 24 ');//define a font and style
$this->cell (40,20, $country, 15);//show information about each country
$this->image ($nationalFlag, $imageX, $imageY);//The position of the national flag
$this->setx (' 70 ');//Set the coordinates of the national flag
$this->settextcolor (200,160,12);//Set the color of the gold medal
$this->cell (40,20, $goldTotal);//Show Gold number
$this->setx (' 100 ');//Set the display position of the gold medal number
$this->settextcolor (170,162,138);//Set the color of the silver
$this->cell (40,20, $silverTotal);//show number of silver medals
$this->setx (' 130 ');//Set the display position of the silver number
$this->settextcolor (187,120,68);//Set the color of the bronze
$this->cell (40,20, $copperTotal);//Show the location of the silver medal
$this->ln ()///Line Wrap
$this->settextcolor (0,0,0);//Because the colors you set are valid throughout the page, you can restore the original color every time you enter a country's information
}
}
The various methods used to explain:
1. SetFont (String family [, string style [, float size]])
Sets the font for the string. The font set by this method is tried in the entire PDF file before the text or the entire article is displayed.
parameter 1:family, set the font you want.
Parameter 2:style, set style. (The empty string represents the plain text, the U represents the Underline, B represents the bold, and I represents the italic).
Parameter 3:size, the size of the font.
2, Cell (float w [, float h [, string txt]])
Displays a cell (rectangular range), and also provides other functional options, including (border, background color, string). The position of the upper-left corner of the cell is the current position.
Note: There are other parameters in the method that are not listed. Because it was not used in the experiment.
Parameter 1:w the cell width. If: 0, the cell extends to the right edge of the page.
Parameter 2: The height of the storage cell. The default value is: 0.
Parameter 3:txt, to print out the content.
3, Ln ([float h])
Complete the line break, and wrap the line. Changes to the current (x,y) coordinates, the horizontal axis (x) is returned to the left edge, and the ordinate (y) height is increased.
Parameter 1:h, the distance or height of the next line. The default value is: Height is equal to the height displayed last.
4, SetTextColor (int r [, int g, int b])
Defines the color used for text. You can use RGB color or grayscale mode to define. This feature can be set up before one page, and that color value will remain on one page to another page.
4, the class has been defined, the last call
Copy Code code as follows:
$pdf =new PDF ();//Instantiate class
$pdf->addpage ();
$imageX =40;//to set the initial x value of a picture
Set the initial Y-value of a picture $imageY =15;//
foreach ($platle as $key => $value) {
$pdf->createhead ($value [' Country '], $value [' Nationalflag '], $imageX, $imageY, $value [' Glod '], $value [' Silver '],$ value[' copper ']);
$imageY +=20;
}
$pdf->output ()//output PDF
Note:
1. The AddPage () method is used to generate a new page. A new page is generated each time the call is invoked.
2, Output () method is used to export the PDF.
