Question

我有pdf文件。我想用php打印pdf的详细信息，如页面大小。

我有这段代码

<?php 

  $pdffile = "C:\Users\suresh\Downloads\Invoice_52683.pdf";
  $pdfinfo = shell_exec("pdfinfo ".$pdffile); 

  // find height and width
  preg_match('/Page size:\s+([0-9]{0,5}\.?[0-9]{0,3}) x ([0-9]{0,5}\.?[0-9]{0,3})/',      $pdfinfo,$heightandwidth); 
  echo $width = $heightandwidth[1]; 
  echo $height = $heightandwidth[2]; 

 ?>

这是我的代码可以为此提供任何帮助。

提前致谢

        return builder;

首先检查您的pdfinfo路径，如果您没有：XPDF ...那么请更改您的代码：

$pdffile = "C:\\Users\\suresh\\Downloads\\Invoice_52683.pdf";
$pdfinfo_path = "C:\\path\\to\\pdfinfo.exe";
$pdfinfo = shell_exec($pdfinfo_path." ".$pdffile);

// find height and width
preg_match('/Page size:\s+([0-9]{0,5}\.?[0-9]{0,3}) x ([0-9]{0,5}\.?[0-9]{0,3})/',$pdfinfo,$heightandwidth); 
echo $width = $heightandwidth[1]; 
echo $height = $heightandwidth[2];

如果您使用Linux：$pdfinfo_path = "/path/to/pdfinfo";

使用PHP获取pdf文件的属性
