下面的就是生成EAN_13标准的条码的PHP方法,需要php+gd 环境:
- <?
- function EAN_13($code) {
- //一个单元的宽度
- $lw = 2;
- //条码高
- $hi = 100;
- // the guide code is no coding,is used to show the left part coding type//
- // Array guide is used to record the EAN_13 is left part coding type//
- $Guide = array(1=>'AAAAAA','AABABB','AABBAB','ABAABB','ABBAAB','ABBBAA','ABABAB','ABABBA','ABBABA');
- $Lstart ='101';
- $Lencode = array("A" => array('0001101','0011001','0010011','0111101','0100011','0110001','0101111','0111011','0110111','0001011'),
- "B" => array('0100111','0110011','0011011','0100001','0011101','0111001','0000101','0010001','0001001','0010111'));
- $Rencode = array('1110010','1100110','1101100','1000010','1011100',
- '1001110','1010000','1000100','1001000','1110100');
- $center = '01010';
- $ends = '101';
- if ( strlen($code) != 13 )
- { die("UPC-A Must be 13 digits."); }
- $lsum =0;
- $rsum =0;
- for($i=0;$i<(strlen($code)-1);$i++)
- {
- if($i % 2)
- {
- // $odd += $ncode[$x]
- $lsum +=(int)$code[$i];
- }else{
- $rsum +=(int)$code[$i];
- }
- }
- $tsum = $lsum*3 + $rsum;
- if($code[12] != (10-($tsum % 10)))
- {
- die("the code is bad!");
- }
- // echo $Guide[$code[0]];
- $barcode = $Lstart;
- for($i=1;$i<=6;$i++)
- {
- $barcode .= $Lencode [$Guide[$code[0]][($i-1)]] [$code[$i]];
- }
- $barcode .= $center;
- for($i=7;$i<13;$i++)
- {
- $barcode .= $Rencode[$code[($i)]] ;
- }
- $barcode .= $ends;
- $img = ImageCreate($lw*95+60,$hi+30);
- $fg = ImageColorAllocate($img, 0, 0, 0);
- $bg = ImageColorAllocate($img, 255, 255, 255);
- ImageFilledRectangle($img, 0, 0, $lw*95+60, $hi+30, $bg);
- $shift=10;
- for ($x=0;$x<strlen($barcode);$x++) {
- if (($x<4) || ($x>=45 && $x<50) || ($x >=92))
- {
- $sh=10;
- } else {
- $sh=0;
- }
- if ($barcode[$x] == '1')
- {
- $color = $fg;
- } else {
- $color = $bg;
- }
- ImageFilledRectangle($img, ($x*$lw)+30,5,($x+1)*$lw+29,$hi+5+$sh,$color);
- }
- /* Add the Human Readable Label */
- ImageString($img,5,20,$hi+5,$code[0],$fg);
- for ($x=0;$x<6;$x++) {
- ImageString($img,5,$lw*(8+$x*6)+30,$hi+5,$code[$x+1],$fg);
- ImageString($img,5,$lw*(53+$x*6)+30,$hi+5,$code[$x+7],$fg);
- }
- // ImageString($img,4,$lw*95+17,$hi-5,$code[12],$fg);
- /* Output the Header and Content. */
- header("Content-Type: image/png");
- ImagePNG($img);
- //phpfensi.com
- }
- EAN_13('6901028055048');
- ?>
