2023-06-13 09:15:11 时间

下面的就是生成EAN_13标准的条码的PHP方法,需要php+gd环境 
  

复制代码代码如下:
<?
functionEAN_13($code){
 //一个单元的宽度
 $lw=2;
 //条码高 
 $hi=100;
 //theguidecodeisnocoding,isusedtoshowtheleftpartcodingtype//
 //ArrayguideisusedtorecordtheEAN_13isleftpartcodingtype//
 $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-AMustbe13digits.");}
$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("thecodeisbad!");
   } 

 //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);
 }
 /*AddtheHumanReadableLabel*/
 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);
 /*OutputtheHeaderandContent.*/
 header("Content-Type:image/png");
 ImagePNG($img);

}

EAN_13("6901028055048");
