Question

我正在研究PHP。我需要将值传递给图像PHP页面，并创建一个图像，但它不起作用。

这个文件是生成php：

   if ( $submit == "View Report" )
   {

       header("Content-Type: application/pdf");


        flush();

       // Run HTMLDOC to provide the PDF file to the user...
       // Use the --no-localfiles option for enhanced security!
        passthru("htmldoc --no-localfiles --no-compression -t pdf14 --quiet --jpeg --browserwidth 1100 --webpage ".
          "--color --linkcolor 000099 --bodyfont Sans-Serif --fontsize 8 ".
          " --landscape --header ctl --footer ..: --headfootfont Sans-Serif --headfootsize 8 --size Letter ".
          " --logoimage https://".$urlbase."ewaclogo.jpg ".
          " https://".$urlbase."ewac_cancertreport.php?dates=".$dataendyear.":".
          "01:01:".$dataendyear.":12:31:".$dataendyear.":".$dataendmonth.":".$dataendday);

    ------------------------------------------------------------------------

other PHP files:

    echo '<BR>'."\n".
     '<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>'."\n".
     '  <TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>'."\n";
echo "    <IMG SRC=\"ewac_cancertsummarygraph.php?startdate=".$startdate."&enddate=".$enddate.
            "&dataenddate=".$dataenddate."&size=1000\">".
     "</TD></TR></TABLE>"."\n";
echo "<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER>

     "</TABLE>"."\n";

echo '<BR>'."\n".
     '<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>'."\n".
     '  <TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>'."\n";

          Figure 2 - CanCERT Incident Summary '.($dataendyear-1).'/'.$dataendyear.' Comparison</TD>'."\n".
     '</TABLE>'."\n";

  echo "<!-- PAGE BREAK -->";

当我检查＆＃34;查看源＆＃34;时，它显示如下，看起来没问题。我不知道问题出在哪里，但图像没有显示出来。

<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>
<TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>

Answer 1

您向我们展示了生成HTML的PHP，而不是生成图像的PHP。这就是问题所在。

您引用的内容在呈现为文本（或HTML）时看起来像是图像文件的开头。

默认情况下，PHP输出Content-Type: text/html标题（告诉浏览器它是HTML）。您需要覆盖它（使用header()方法）为您正在使用的图像格式指定正确的内容类型（例如image/jpeg）。

Answer 2

这样更清洁。

<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>
    <TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>
    <IMG SRC="ewac_cancertcomparisongraph.php?startdate=<?php echo $startdate."&enddate=".$enddate."&dataenddate=".$dataenddate."&size=".$size;?>"></TD></TR></TABLE>
<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER>
     Figure 1 - 2016 CanCERT Incident Summary</TD>
</TABLE>
<!-- PAGE BREAK --><BR>
<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>
    <TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>
    <IMG SRC="ewac_cancertcomparisongraph.php?startdate=<?php echo $startdate."&enddate=".$enddate."&dataenddate=".$dataenddate."&size=".$size;?>"></TD></TR></TABLE>
<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER>
    Figure 2 - CanCERT Incident Summary 2015/2016 Comparison</TD>

IMG SRC不能在PHP中工作
