使用PHPExcel将xlsx转换为pdf并下载该pdf。 在localhost上工作正常

Question

This code works fine on localhost but on live server it shows

File Not Found

Check the file name for capitalization or other typing errors. Check to see if the file was moved, renamed or deleted.

Here is my code

excel.php

<?php

error_reporting(1);
ini_set('display_errors', 0);
ini_set('display_startup_errors', TRUE);

$target = 'Myfile.xlsx';
include 'phpexcel/Classes/PHPExcel/IOFactory.php';
$inputFileType = PHPExcel_IOFactory::identify($target);

function datefix_excel($excel) {

    $dif=(41885-$excel)*86400;
    $seconds=1409737670-$dif;
    $date=date("d/m/Y",$seconds);
    return $date; }

//echo 'File ',pathinfo($inputFileName,PATHINFO_BASENAME),' has been identified as an ',$inputFileType,' file<br />';

//echo 'Loading file ',pathinfo($inputFileName,PATHINFO_BASENAME),' using IOFactory with the identified reader type<br />';
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($target);

$i = 0;
$found = false;
try
{



    //
    foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) 
    {

    //
    //$objWorksheet = $objPHPExcel->getActiveSheet();
    //now do whatever you want with the active sheet

    $worksheet->setShowGridLines(false);
    $worksheet->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A2_PAPER );
    $worksheet->getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A2_PAPER );
    $worksheet->getPageSetup()->setFitToPage(true);
    $worksheet->getPageSetup()->setFitToWidth(1);
    $worksheet->getPageSetup()->setFitToHeight(0);

    $worksheet->getPageSetup()->setScale(40);
    $worksheet->getStyle('F1:F4')->getAlignment()->setWrapText(false);
    $worksheet->getStyle('D6:D8')->getAlignment()->setWrapText(false);


    $sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
    $count = 0;

    //

Answer 1

I would check: 1) is current folder writeable? 2) pdf.php is commented out, try enabling it (why? local machine probably has PDF installed, server does not), 3) try saving to file instead of outputting to browser, this will bypass any browser / security issues.
