如何使用PHP將圖像插入Word文檔？

Question

是否有任何Microsoft Word文檔操作庫允許打開已經創建的Word文檔並向其中插入外部圖像？ phpoffice/phpword和PHPWord似乎都無法處理任務。

好的，基於@Mark Ba​​ker的回答。我創建了一個子類，這樣就不需要覆蓋原始的TemplateProcessor。

<?php 
class TemplateProcessor extends \PhpOffice\PhpWord\TemplateProcessor 
{ 
    /** 
    * Content of document rels (in XML format) of the temporary document. 
    * 
    * @var string 
    */ 
    private $temporaryDocumentRels; 

    public function __construct($documentTemplate) 
    { 
     parent::__construct($documentTemplate); 
     $this->temporaryDocumentRels = $this->zipClass->getFromName('word/_rels/document.xml.rels'); 
    } 

    /** 
    * Set a new image 
    * 
    * @param string $search 
    * @param string $replace 
    */ 
    public function setImageValue($search, $replace){ 
     // Sanity check 
     if (!file_exists($replace)) { 
      throw new \Exception("Image not found at:'$replace'"); 
     } 

     // Delete current image 
     $this->zipClass->deleteName('word/media/' . $search); 

     // Add a new one 
     $this->zipClass->addFile($replace, 'word/media/' . $search); 
    } 

    /** 
    * Search for the labeled image's rId 
    * 
    * @param string $search 
    */ 
    public function seachImagerId($search){ 
     if (substr($search, 0, 2) !== '${' && substr($search, -1) !== '}') { 
      $search = '${' . $search . '}'; 
     } 
     $tagPos = strpos($this->temporaryDocumentRels, $search); 
     $rIdStart = strpos($this->temporaryDocumentRels, 'r:embed="',$tagPos)+9; 
     $rId=strstr(substr($this->temporaryDocumentRels, $rIdStart),'"', true); 
     return $rId; 
    } 

    /** 
    * Get img filename with it's rId 
    * 
    * @param string $rId 
    */ 
    public function getImgFileName($rId){ 
     $tagPos = strpos($this->temporaryDocumentRels, $rId); 
     $fileNameStart = strpos($this->temporaryDocumentRels, 'Target="media/',$tagPos)+14; 
     $fileName=strstr(substr($this->temporaryDocumentRels, $fileNameStart),'"', true); 
     return $fileName; 
    } 

    public function setImageValueAlt($searchAlt, $replace) 
    { 
     $this->setImageValue($this->getImgFileName($this->seachImagerId($searchAlt)),$replace); 
    } 
} 

這樣，我只有做你跟PHPWord有什麼問題

<?php 
$template = new TemplateProcessor('path/to/my/template.docx'); 
$template->setImageValueAlt('myPicturePlacehoder', '/tmp/pictureToReplace.png');
