Unix command line CURL equivalent in PHP CURL

[kokopeti]

The following snippet is from "http://pdfx.cs.man.ac.uk/usage". This very great tool and it converts scientific papers in pdf to xml. \[code\]curl --data-binary @"/path/to/my.pdf" -H "Content-Type: application/pdf" -L "http://pdfx.cs.man.ac.uk"\[/code\]This code is unix command line code and I want its PHP version. I have tried \[code\]$pdfFile = fopen('jucs_18_05_0623_0649_hasan.pdf', 'r');$fileSize = filesize ('jucs_18_05_0623_0649_hasan.pdf');$url="http://pdfx.cs.man.ac.uk";$ch=curl_init();curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // curl_setopt($ch, CURLOPT_TIMEOUT, 100);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_PUT, true);curl_setopt($ch, CURLOPT_INFILE, $pdfFile);curl_setopt($ch, CURLOPT_INFILESIZE, $fileSize);curl_setopt($ch, CURLOPT_VERBOSE, true);$fp = fopen("test.xml", "w");curl_setopt($ch, CURLOPT_FILE, $fp);if (! $res = curl_exec($ch)) echo "Error: ".curl_error($ch);else { echo "Success";} curl_close($ch);\[/code\]The problem is the output to the test.xml is the index file html code instead of converted xml version of the provided article. Waiting for your expert opinion...Thanks in advance
