为Laravel提供PDF转HTML、HTML转PDF、DOC转PDF、HTML转图片的功能

在composer.json中添加此包并更新composer。

    composer require workable-cv/extract

安装

更新composer后，将ServiceProvider添加到config/app.php文件中的providers数组中

1. Laravel

    WorkableCV\Extract\ExtractServiceProvider::class

2. Lumen

    $app->register(\WorkableCV\Extract\ExtractServiceProvider::class);

配置

1. Laravel

    php artisan vendor:publish --provider="WorkableCV\Extract\ExtractServiceProvider"

2. Lumen

第一步

    composer require laravelista/lumen-vendor-publish

第二步

为了使用它，您必须将其添加到您的app/Console/Kernel.php文件中

protected $commands = [
    \Laravelista\LumenVendorPublish\VendorPublishCommand::class
];

最后一步

php artisan vendor:publish --provider="WorkableCV\Extract\ExtractServiceProvider"

Laravel 5.x

I. PDF转HTML

1. 安装Poppler-Utils

Debian/Ubuntu

    sudo apt-get install poppler-utils

Mac OS X

    brew install poppler

Window

对于需要在Windows上使用此包的用户，有办法。首先在此处下载poppler-utils for windows http://blog.alivate.com.au/poppler-windows/。并下载最新的二进制文件。

下载后，解压它。

2. 我们需要知道工具所在的位置

Debian/Ubuntu

    $ whereis pdftohtml
    pdftohtml: /usr/bin/pdftohtml
    
    $ whereis pdfinfo
    pdfinfo: /usr/bin/pdfinfo

Mac OS X

   /usr/local/bin/pdfinfo
   
   $ which pdftohtml
   /usr/local/bin/pdfinfo

Window

进入解压目录。将有一个名为bin的目录。我们需要这个。

3. PHP配置，启用shell访问

用法

在存储文件夹中创建文件文件夹

示例

    use WorkableCV\Extract\core\PdfToHtml;

    $name_file = 'cv24';
    $file = $name_file . ".pdf";
    $id = uniqid();
    $options = [
        'pdftohtml_path' => '/usr/bin/pdftohtml',
        'pdfinfo_path' => '/usr/bin/pdfinfo'
        'clearAfter' => false,
        'outputDir' => storage_path('files/'.$id),
    ];
    //example for Window
    //$options = [
    //            'pdftohtml_path' => '/path/to/poppler/bin/pdftohtml.exe',
    //            'pdfinfo_path' => '/path/to/poppler/bin/pdfinfo.exe',
    //            'clearAfter' => false,
    //            'outputDir' => storage_path('files/'.$id),
    //        ];
    $pdf = new PdfToHtml($file, $options, 'pdf');
    $pdf->generateHTML($name_file, $id);

完整选项

    $full_settings = [
        'pdftohtml_path' => '/usr/bin/pdftohtml', // path to pdftohtml
        'pdfinfo_path' => '/usr/bin/pdfinfo', // path to pdfinfo
    
        'generate' => [ // settings for generating html
            'singlePage' => false, // we want separate pages
            'imageJpeg' => false, // we want png image
            'ignoreImages' => false, // we need images
            'zoom' => 1.5, // scale pdf
            'noFrames' => false, // we want separate pages
        ],
    
        'clearAfter' => true, // auto clear output dir (if removeOutputDir==false then output dir will remain)
        'removeOutputDir' => true, // remove output dir
        'outputDir' => '/tmp/'.uniqid(), // output dir
    
        'html' => [ // settings for processing html
            'inlineCss' => true, // replaces css classes to inline css rules
            'inlineImages' => true, // looks for images in html and replaces the src attribute to base64 hash
            'onlyContent' => true, // takes from html body content only
        ]
    ]

II. HTML转PDF

用法

示例

    use WorkableCV\Extract\core\HtmlToPdf;

    $html = new HtmlToPdf();
    $file = 'test.html';
    $option = [
        'dpi' => 120
    ];
    $pdf_generate =  $html->generatePDF($path_file, $option);
    return $pdf_generate;

    tempDir: "/tmp" (available in config/dompdf.php)
    fontDir: "{app_directory}/storage/fonts/" (available in config/dompdf.php)
    fontCache: "{app_directory}/storage/fonts/" (available in config/dompdf.php)

III. HTML转图像

用法

在浏览器中复制结构下的html文件路径$id .'_image.html ' ($id由pdf转html生成)并运行文件。打开F12，切换到控制台标签将会有以base64为底图的图像

IV. DOC转PDF

用法

参考https://php.ac.cn/manual/en/book.com.php

要求

Window

添加到php.ini

   [PHP_COM_DOTNET]
   extension=php_com_dotnet.dll

macOs, Linux

    snap install libreoffice
    sudo add-apt-repository ppa:libreoffice/ppa
    sudo apt-get update
    sudo apt-get install libreoffice
    sudo apt-get update -y
    sudo apt-get install -y libreoffice-java-common
    sudo apt-get install default-jre libreoffice-java-common

示例

    use WorkableCV\Extract\core\DocToPdf;
    
    //test.doc is a convert to pdf file.
    //test.pdf is the path to save the test.pdf file
    $doc = new DocToPdf();
    
    //window
    $doc->generatePDF('test.doc', 'test.pdf');
    
    //linux, masOs
    $doc->generatePDFLinux('test.doc');

V. PDF OCR

用法

安装OCRmyPDF : https://ocrmypdf.cn/en/latest/

注意

支持Linux、macOs。不支持window，因为与权限有关。

示例

    use WorkableCV\Extract\core\PdfOCR;
        
    //test.pdf is a convert to path pdf file.
    //test.ocr.pdf is the path pdf file to ouput
    $pdfOCR = new PdfOCR();
    $pdfOCR->pdfOCR('test.pdf', 'test.ocr.pdf');

VI. PDF受保护

注意

在任何人可以这样做之前，您必须阅读上述内容并安装上述所有所需的包。
支持Linux、macOs。不支持window，因为与权限有关。
所有配置选项都写在extract.php文件中

示例

    use WorkableCV\Extract\core\PdfOCR;
    use WorkableCV\Extract\core\PdfProtected;
    use WorkableCV\Extract\core\PdfToHtml;
        
    $name_file = 'cv105';

    $file      = storage_path('cv1/' . $name_file . '.pdf');

    $options_check = config('extract.options_extract');

    $pdf           = new PdfToHtml($file, $options_check);

    $output_dir = config('extract.options_extract.outputDir');
    
    //Check pdf file scan from dom element or image
    $checkPdf = $pdf->checkPdf($output_dir, $name_file);
        
    if ($checkPdf)
    {
        $pdfOCR = new PdfOCR();

        $result_pdfOCR = $pdfOCR->pdfOCR($file);

        if (!$result_pdfOCR) exit('File not convert. Try again');

        $path_file_ocr = $result_pdfOCR[1];
        
        $pdfProtected = new PdfProtected($path_file_ocr, $options_check);

        $path_cv_protected = $pdfProtected->pdfProtected($name_file, $output_dir, false, false, 'pdf', 1,  config('extract.output_cv_protected'), false);

        unlink($path_file_ocr);

    }
    else
    {
        //Check pdf file exist email or phone
        $checkExistEmailPhone = $pdf->checkExitsEmailPhone($output_dir, $name_file);

        if (!$checkExistEmailPhone)
        {
            $pdfOCR = new PdfOCR();

            $result_pdfOCR = $pdfOCR->pdfOCR($file);

            if (!$result_pdfOCR) exit('File not convert. Try again');

            $path_file_ocr = $result_pdfOCR[1];
            
            $pdfProtected = new PdfProtected($path_file_ocr, $options_check);

           $path_cv_protected = $pdfProtected->pdfProtected($name_file, $output_dir, false, false, 'pdf', 1,  config('extract.output_cv_protected'), false);

            unlink($path_file_ocr);
        }
        else
        {
            $pdfProtected = new PdfProtected($file, $options_check);

            $path_cv_protected = $pdfProtected->pdfProtected($name_file, $output_dir, false, false, 'pdf', 1,  config('extract.output_cv_protected'), false);
