Example of using GD to output Chinese characters in PHP

(Wang Feng)
I. Principles
The GD Library in PHP supports Chinese, but must be passed in UTF-8 format parameters. Next let's talk about the UTF-8 encoding of Chinese characters. Use Notepad in WORD2000 or WINDOW 2000 to edit the Chinese characters to be displayed.
Save the edited text to a file in UTF-8 format.
Open the file with a hexadecimal editor (such as the EDIT function of PCTOOLS). Then, you will see some hexadecimal characters in the opened file. A Chinese character occupies three bytes, so you should select to edit the number of Chinese characters multiplied by three bytes, and record the encoding for future use. For example, the code of CCID is E8 B5 9B E8 bf aa E7 BD 91.
II. Implementation
In this example, the image output of CCID www.ccidnet.com is implemented. The file name is ttf. php. <? Php
// Define output as image type
Header ("content-type: image/gif ");
// Create an image
$ Pic = imagecreate (240,30 );
// Define the black and white colors
$ Black = imagecolorallocate ($ pic, 0, 0 );
$ White = imagecolorallocate ($ pic, 255,255,255 );
// Define the font
$ Font = "c: // WIN2000 // fonts // simhei. ttf ";
// Define the output font string
$ Str = chr (0xE8 ). chr (0xB5 ). chr (0x9B ). chr (0xE8 ). chr (0xBF ). chr (0xAA ). chr (0xE7 ). chr (0xBD ). chr (0x91 ). "www.ccidnet.com ";
// Write TTF text to the graph
Imagettftext ($ pic, 20, 0, 10, 20, $ white, $ font, $ str );
// Create a GIF image
Imagegif ($ pic );
// End the image and release the memory space
Imagedestroy ($ pic );
?>
