IMG SRC不能在PHP中工作

Question

我正在使用PHP。我需要將值傳遞給圖像PHP頁面，並創建一個圖像，但它不起作用。

此文件是生成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=".$dataenddate."&size=1000\">". 
    "</TD></TR></TABLE>"."\n"; 
echo "<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER> 
    Figure 1 - ".$startyear." CanCERT Incident Summary</TD>"."\n". 
    "</TABLE>"."\n"; 

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

echo '<BR>'."\n". 
    '<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0>'."\n". 
    ' <TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER>'."\n"; 
echo " <IMG SRC=\"ewac_cancertcomparisongraph.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> 
      Figure 2 - CanCERT Incident Summary '.($dataendyear-1).'/'.$dataendyear.' Comparison</TD>'."\n". 
    '</TABLE>'."\n"; 

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

當我選中「查看源文件」，它顯示如下，它看起來OK。我不知道問題出在哪裏，但圖像沒有顯示出來。

<TABLE WIDTH=50% CELLSPACING=0 CELLPADDING=2 BORDER=0> 
<TR BGCOLOR="#FFFFFF"><TD ALIGN=CENTER> 
<IMG SRC="ewac_cancertsummarygraph.php?startdate=2016-1-1&enddate=2016-12-31&dataenddate=2016-4-11&size=1000"></TD></TR></TABLE> 
<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER>

<TABLE WIDTH=1000 CELLSPACING=0 CELLPADDING=2 BORDER=0><TR><TD ALIGN=CENTER> 
    Figure 2 - CanCERT Incident Summary 2015/2016 Comparison</TD> 

當我檢查只有圖像，它表明：

Answer 1

您向我們展示了生成HTML的PHP​​，但不生成圖像的PHP。這就是問題所在。

您引用的內容看起來像文本（或HTML）渲染時的圖像文件的開頭。

默認情況下，PHP輸出一個Content-Type: text/html標題（告訴瀏覽器它是HTML）。您需要覆蓋（使用方法header()）爲您正在使用的圖像格式（例如image/jpeg）指定正確的內容類型。

Answer 2

這是方式更清潔。
