PHP將ppt轉(zhuǎn)成圖片查看
PHP安裝COM組件
1、如php版本>5.3.15,需要保證ext文件夾下有php_com_dotnet.dell 并在php.ini中加入。
extension=php_com_dotnet.dll
2、去除com.allow_dcom = true前面的‘;'號。
實(shí)例
$powerpnt = new COM("powerpoint.application") or die("Unable to instantiate Powerpoint");
$file='E:/APP/OTHER/qwe.pptx';
$presentation = $powerpnt->Presentations->Open(realpath($file), false, false, false) or die("Unable to open presentation");
foreach($presentation->Slides as $slide)
{
$slideName = "Slide_" . $slide->SlideNumber;
$uploadsFolder = 'iii';
$exportFolder = realpath($uploadsFolder);
$slide->Export($exportFolder."http://".$slideName.".jpg", "jpg", "600", "400");
}
$presentation->Close();
$powerpnt->Quit();
$powerpnt = null;
?>
內(nèi)容擴(kuò)展:
從shell腳本中,您可以使用Unoconv,它是LibreOffice的簡單命令行包裝器,可以使您轉(zhuǎn)換為合理的質(zhì)量。
對于可以直接從PHP(以及Linux)調(diào)用的具有更高質(zhì)量輸出的解決方案,您可以使用專用文件轉(zhuǎn)換API,例如Zamzar。
提交PPT(或PPTX)文件以轉(zhuǎn)換為JPEG的代碼如下(documentation中的更多信息):
/ Build request
$endpoint = "https://api.zamzar.com/v1/jobs";
$apiKey = "YOUR_KEY";
$sourceFilePath = "/tmp/my.ppt"; // Or PPTX
$targetFormat = "jpg";
$sourceFile = curl_file_create($sourceFilePath);
$postData = array(
"source_file" => $sourceFile,
"target_format" => $targetFormat
);
// Send request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $endpoint);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $apiKey . ":");
$body = curl_exec($ch);
curl_close($ch);
// Process response (with link to converted files)
$response = json_decode($body, true);
print_r($response);
?>
