一、去官網下載類庫 「[https://www.barcodebakery.com...]」,選擇本身的版本下載php
二、解壓放到「E:\phpstudy\PHPTutorial\WWW\guahao\vendor\下」,其中class文件是全部的類文件,生成條形碼就是調用文件夾裏的類,font文件是字體,index.php是一個可選擇條件生成條形碼的功能,是主程序的入口,test_1D.php是給的生成條形碼的例子,test_1D.html是對應的渲染條形碼的頁面html
三、咱們能夠直接使用官方給的例子(test_1D.php),複製到本身須要用的地方,而後根據本身的需求稍加改動便可,須要注意的是,加載第三方類庫的路徑須要改一下。app
生成條形碼的php代碼字體
<?php namespace app\index\controller; use think\Controller; /** * 條形碼操做類 */ class Barcode extends Controller { public function createBarcode() { $class_dir = VENDOR_PATH.'barcode/class/'; // Including all required classes require_once($class_dir.'BCGFontFile.php'); require_once($class_dir.'BCGColor.php'); require_once($class_dir.'BCGDrawing.php'); require_once($class_dir.'BCGcode39.barcode.php'); // Loading Font // 注意font和class是同一級文件夾 $font = new \BCGFontFile(VENDOR_PATH.'barcode/font/Arial.ttf', 18);// The arguments are R, G, B for color. $color_black = new \BCGColor(0, 0, 0); $color_white = new \BCGColor(255, 255, 255); $drawException = null; try { $code = new \BCGcode39(); $code->setScale(2); // Resolution $code->setThickness(30); // Thickness $code->setForegroundColor($color_black); // Color of bars $code->setBackgroundColor($color_white); // Color of spaces $code->setFont($font); // Font (or 0) 0不顯示文字 $text = isset($_GET['text']) ? $_GET['text'] : 'HELLO'; $code->parse($text); // Text } catch(Exception $exception) { $drawException = $exception; } /* Here is the list of the arguments - Filename (empty : display on screen) - Background color */ $drawing = new \BCGDrawing('', $color_white); if($drawException) { $drawing->drawException($drawException); } else { $drawing->setBarcode($code); $drawing->draw(); } // Header that says it is an image (remove it if you save the barcode to a file) header('Content-Type: image/png'); header('Content-Disposition: inline; filename="barcode.png"'); // Draw (or save) the image into PNG format. $drawing->finish(\BCGDrawing::IMG_FORMAT_PNG); } public function barcodedes() { return $this->fetch(); } } ?>
接受渲染條形碼的Html代碼fetch
<img src="{:url('createBarcode')}">
固然,src還能夠攜帶參數,只需更改如下代碼ui
html代碼this
<img src="{:url('createBarcode',array('text'=>'123'))}">
php代碼把url
$text = isset($_GET['text']) ? $_GET['text'] : 'HELLO';
改爲spa
$text = input('text'); //接收的參數
四、若是想把條形碼保存到本地,在實例化「BCGDrawing」的時候_填寫保存路徑便可_3d
// 文件路徑 $file_dir = 'uploads/barcode/'.date('Y-m-d'); if (!file_exists($file_dir)) { mkdir($file_dir,0755,true); } $imgUrl = $file_dir.'/'.time().'.png'; $class_dir = VENDOR_PATH.'barcode/class/'; // Including all required classes require_once($class_dir.'BCGFontFile.php'); require_once($class_dir.'BCGColor.php'); require_once($class_dir.'BCGDrawing.php'); require_once($class_dir.'BCGcode39.barcode.php'); // Loading Font // 注意font和class是同一級文件夾 $font = new \BCGFontFile(VENDOR_PATH.'barcode/font/Arial.ttf', 18); // Don't forget to sanitize user inputs // $text = isset($_GET['text']) ? $_GET['text'] : 'HELLO'; // The arguments are R, G, B for color. $color_black = new \BCGColor(0, 0, 0); $color_white = new \BCGColor(255, 255, 255); $drawException = null; try { $code = new \BCGcode39(); $code->setScale(2); // Resolution $code->setThickness(30); // Thickness $code->setForegroundColor($color_black); // Color of bars $code->setBackgroundColor($color_white); // Color of spaces $code->setFont($font); // Font (or 0) $text = input('text'); //接收的參數 $text = isset($text) ? $text :'無參數'; $code->parse($text); // Text } catch(Exception $exception) { $drawException = $exception; } /* Here is the list of the arguments - Filename (empty : display on screen) - Background color */ // 保存到本地 (路徑,顏色)路徑爲空則表示顯示到頁面上 $drawing = new \BCGDrawing($imgUrl, $color_white); if($drawException) { $drawing->drawException($drawException); } else { $drawing->setBarcode($code); $drawing->draw(); } $drawing->finish(\BCGDrawing::IMG_FORMAT_PNG);
五、生成條形碼以後,怎麼斷定條形碼是否能用呢?
能夠把條形碼保存成圖片到本地,打開官網「[https://www.onlinebarcoderead...]」,上傳剛剛生成的條形碼,若是解析出的參數跟你輸入的同樣,說明條形碼能夠用。
