当我尝试创建 PDF 文件时出现以下错误?
我不知道为什么,也不知道如何解决?
错误如下所示
`
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\phpexample\createpdf.php:1) in C:\xampp\htdocs\phpexample\fpdf16\fpdf.php on line 1017`<br/>
`FPDF error: Some data has already been output, can't send PDF file`<br/>
我的代码是这样的
<?php
include_once('fpdf16/fpdf.php');$pdf=new FPDF();
$pdf->AddPage();
$reportdate = date('d-m-Y H:i:s');
$filename = $reportdate.'_report.pdf';
$pdf->SetFillColor(255,0,0);
$pdf->SetTextColor(255);
$pdf->SetDrawColor(128,0,0);
$pdf->SetLineWidth(.3);
$pdf->SetFont('Arial', 'B', 6);
// Header
$header=array('Member Card No','Full Name','Description', 'Start Date', 'Expiry Date', 'ramount', 'Address1', 'Address2');
$w = array(25, 35, 35, 15, 18, 15, 30, 30);
for($i=0;$i<count($header); $i++)
$pdf->Cell($w[$i],7, $header[$i], 1, 0, 'L', true);
$pdf->Ln();
// Reset colour set for data
$pdf->SetFillColor(224,235,255);
$pdf->SetTextColor(0);
$pdf->SetFont('courier','',7);
$fill=false;
$resultcount=8;
for($i=0;$i<$resultcount;$i++)
{
$height =6;
$pdf->Cell($w[0], '$height', 'CardNoishai', '1', '0', 'L', $fill);
$pdf->Cell($w[1], '$height', 'Vinoth', '1', '0', 'L', $fill);
$pdf->Cell($w[2], '$height', 'Sample PDF', '1', '0', 'L', $fill);
$pdf->Cell($w[3], '$height', date('m-d-y'), '1', '0', 'L', $fill);
$pdf->Cell($w[4], '$height', date('m-d-y'), '1', '0', 'L', $fill);
$pdf->Cell($w[5], '$height', 'test', '1', '0', 'L', $fill);
$pdf->Cell($w[5], '$height', 'test', '1', '0', 'L', $fill);
$pdf->Cell($w[5], '$height', 'Add2', '1', '0', 'L', $fill);
$pdf->Ln();
$fill = !$fill;
}
$pdf->Cell(array_sum($w),0,'','T');
$pdf->Output($filename, 'I');
?>
最佳答案
删除开始 php 标记前的空格。
关于php - 使用 FPDF :Some data has already been output, 无法发送 PDF 文件的 fatal error ?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/3530183/
