报如下错误
function pdf2png($PDF,$toPath,$page){ if(!extension_loaded('imagick')){ echo "imagick"; return false; } if(!file_exists($PDF)){ echo "noexists"; return false; } $IM = new imagick(); $IM->setResolution(1000,2000); $IM->setCompressionQuality(100); $IM->readImage($PDF."[".$page."]"); foreach ($IM as $Key => $Var){ $Var->setImageFormat('png'); $Filename = $toPath.time().'_'.$Key.'.png'; if($Var->writeImage($Filename) == true){ $Return[] = $Filename; } } return $Return;}
回复讨论(解决方案)
他说的很明确了,papers/1375680721.pdf 不存在
他说的很明确了,papers/1375680721.pdf 不存在 不是这个原因,文件是存在的
'unable to open image `papers/1375680721.pdf': No such file or directory
“无法打开图像papers/1375680721.pdf”:没有这样的文件或目录
'unable to open image `papers/1375680721.pdf': No such file or directory
“无法打开图像papers/1375680721.pdf”:没有这样的文件或目录
@ error/blob.c/OpenBlob/2622' 这个错误是什么意思?
'unable to open image `papers/1375680721.pdf': No such file or directory
“无法打开图像papers/1375680721.pdf”:没有这样的文件或目录
if(!file_exists($PDF)){ echo "noexists"; return false; }
如果文件真不存在,过不了这个判断的
看看是不是文件权限问题,把papers/1375680721.pdf,权限设成777
看看是不是文件权限问题,把papers/1375680721.pdf,权限设成777 也不是权限问题,我怀疑是imagemagick有问题,我打开imagemagick把pdf文件丢进去,提示
if(!file_exists($PDF)) 只是检查了 $PDF 指向的文件是否存在
而你打开 pdf 的语句是 $IM->readImage($PDF."[".$page."]");
显然 $PDF 和 $PDF."[".$page."]" 不是一回事
你的这个写法是从哪里看来的?请给出出处!
我搜索到的相关代码中都没有见到这个写法
如果说 $PDF."[".$page."]" 是表示 $PDF 的第 $page 也得话,那么若 $page 所表示的页不存在的话,是否也应该报错呢?
我没有 imagick 环境,无法测试。只是按常理推导
Windows系统下运行,还需要装一个安装软件ghostscript;下载地址:http://downloads.ghostscript.com/public/gs904w32.exe ; 祝你成功。

The PHP Client URL (cURL) extension is a powerful tool for developers, enabling seamless interaction with remote servers and REST APIs. By leveraging libcurl, a well-respected multi-protocol file transfer library, PHP cURL facilitates efficient execution of various network protocols, including HTTP, HTTPS, and FTP.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
