解决FPDF报错:FPDF error: Not a JPEG file / FPDF error: Not a PNG file

最近有个项目需要用到FPDF,但是输出的时候报错:

FPDF error: Not a JPEG file: http://***/data/attachment/forum/201603/19/105428nzhz6z9eh6qyyiw8.jpg

 找到报错的代码:

 

用到了getimagesize函数来做判断,那就简单试下:

<?php
/**
 * User: Administrator
 * Date: 2016/3/22 11:54
 */
header("Content-type: text/html; charset=utf-8");

$a = getimagesize('105428nzhz6z9eh6qyyiw8.jpg');
var_dump($a);

结果如下:

array (size=6)
  0 => int 282
  1 => int 500
  2 => int 3
  3 => string 'width="282" height="500"' (length=24)
  'bits' => int 8
  'mime' => string 'image/png' (length=9)

 

发现了比较奇怪的现象:后缀为jpg,但是mime的结果却是image/png!!!!

 

发现问题就比较好解决了,由于我的图片是其他地方用到的,那就是复制个105428nzhz6z9eh6qyyiw8.jpg到105428nzhz6z9eh6qyyiw8.png即可,试了下,完美解决!

附上代码:

$imgurl=$imgtemp['attachment'];
$imgtype = substr($imgurl,strrpos($imgurl,'.')+1);
$a = getimagesize('../data/attachment/forum/'.$imgurl);
$mime =str_replace('jpeg','jpg', str_replace('image/','',$a['mime']));
if($imgtype != $mime){
  $imgurl_new = '/data/attachment/forum/'.str_replace($imgtype,$mime,$imgurl);
  if(!is_dir($imgurl_new)){
    $jpg = '/data/attachment/forum/'.$imgurl;
    $topng = copy('..'.$jpg,'..'.$imgurl_new);
    $imgurl = str_replace('/data/attachment/forum/','',$imgurl_new);
  }
}
$mypath="http://$baseurl/data/attachment/forum/".$imgurl;

$pdf->Image(''.$mypath.'');
