php使用tbszip合并多个word的时候，图片等资源丢失的办法

楼主为了偷懒，使用了模板替换，但是在合并多个word的时候，内容很好合并，但是图片丢失了，看了一下源码，发现需要添加文件以及更改索引。
方法如下：

在phpword的 TemplateProcessor 类里添加方法：

    public function addImage($partFileName, $rid, $imgPath, $imageMimeType)
    {
        // define templates
        $typeTpl = '<Override PartName="/word/media/{IMG}" ContentType="image/{EXT}"/>';
        $relationTpl = '<Relationship Id="{RID}" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="media/{IMG}"/>';
        $newRelationsTpl = '<?xml version="1.0" encoding="UTF-8" standalone="yes"?>' . "\n" . '<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships"></Relationships>';
        $newRelationsTypeTpl = '<Override PartName="/{RELS}" ContentType="application/vnd.openxmlformats-package.relationships+xml"/>';
        $extTransform = array(
            'image/jpeg' => 'jpeg',
            'image/png'  => 'png',
            'image/bmp'  => 'bmp',
            'image/gif'  => 'gif',
        );

        // get image embed name
        if (isset($this->tempDocumentNewImages[$imgPath])) {
            $imgName = $this->tempDocumentNewImages[$imgPath];
        } else {
            // transform extension
            if (isset($extTransform[$imageMimeType])) {
                $imgExt = $extTransform[$imageMimeType];
            } else {
                throw new Exception("Unsupported image type $imageMimeType");
            }

            // add image to document
            $imgName = 'image_' . $rid . '_' . pathinfo($partFileName, PATHINFO_FILENAME) . '.' . $imgExt;
            $this->zipClass->pclzipAddFile($imgPath, 'word/media/' . $imgName);
            $this->tempDocumentNewImages[$imgPath] = $imgName;

            // setup type for image
            $xmlImageType = str_replace(array('{IMG}', '{EXT}'), array($imgName, $imgExt), $typeTpl);
            $this->tempDocumentContentTypes = str_replace('</Types>', $xmlImageType, $this->tempDocumentContentTypes) . '</Types>';
        }

        $xmlImageRelation = str_replace(array('{RID}', '{IMG}'), array($rid, $imgName), $relationTpl);

        if (!isset($this->tempDocumentRelations[$partFileName])) {
            // create new relations file
            $this->tempDocumentRelations[$partFileName] = $newRelationsTpl;
            // and add it to content types
            $xmlRelationsType = str_replace('{RELS}', $this->getRelationsName($partFileName), $newRelationsTypeTpl);
            $this->tempDocumentContentTypes = str_replace('</Types>', $xmlRelationsType, $this->tempDocumentContentTypes) . '</Types>';
        }

        // add image to relations
        $this->tempDocumentRelations[$partFileName] = str_replace('</Relationships>', $xmlImageRelation, $this->tempDocumentRelations[$partFileName]) . '</Relationships>';
    }

然后把合并的内容存到临时文件，然后重新加载，写入文件：

demo:

        $temp = uniqid(sys_get_temp_dir().'/');
        $zip->Flush(TBSZIP_FILE, $temp);
        $zip->Close();
        $dir = FCPATH . 'resources/upload/files/tempdoc/';
        if (!is_dir($dir)) {
            mkdir($dir, 0777);
        }
        $file = $student_info['name'].'_'.$student_info['student_num'].'_评阅意见表.docx';
        $filename = $dir.$file;
        $filename = iconv("UTF-8","GBK//IGNORE",$filename);
        $PHPWord = new \PhpOffice\PhpWord\PhpWord();
        $template = $PHPWord->loadTemplate($temp);
        $imgAttrs = @getimagesize($this->user['signature'][1]);
        $template->addImage('word/document.xml',$rid,$this->user['signature'][1],$imgAttrs['mime']);
        $template->saveAs($filename);

原理是用zip打开word，然后在 word/media 里添加图片，然后在 word/_rels/document.xml.rels和[Content_Types].xml 里添加索引即可

至此，大功告成。
