該軟體支援PHP4和PHP5兩個版本,本文中使用的是PHP5的版本。在使用前注意要將PHP的GD模組開啟。在Windows中為php_gd2.dll,Linux中為gd.so。將壓縮檔解壓到Apache,執行http://localhost/barcode/index.php。介面見:
1. Type:選擇條碼類型
2. Output:輸出的圖片格式
3. Thickness:條碼高度
4. Resolution:條碼大小
5. Font:條碼下方的文字大小,也可不顯示文字
6. Text:條碼列印的內容
當然,這個程式只是將文字產生為條碼,但使用時不能靈活將其嵌入其他PHP程式,我將壓縮包裡面的test.php
做了一些調整,使其能靈活的用於其他程式。運行時只需將條碼類型和文字傳給test.php即可,例如:
http://localhost/barcode/test.php?codebar=BCGcode39&text=20090729
或運行 http://localhost/barcode/mytest.php
mytest.php代碼:
<img src="test.php?codebar=BCGcode39&text=20090729">
:
test.php代碼:
