Find file type when using fopen

[skip]

Hello all 🙂

How can I get the file type from a string like this one

http://Awebsite.com/image.php?size=large&&imgcode=TMOV3

the plan is to call it somthing and save the image localy can this be done ?

Thanks All in advance 🙂

You can try and use [man]getimagesize[/man] which returns image type as well.

Cheers m8 🙂

Looks like fun can't seem to get the extension from a url like the one above though.

my php isn't great

This: http://Awebsite.com/image.php?size=large&&imgcode=TMOV3
doesn't give you a filetype
A header does, or a file does. A link doesn't

Have tried this

$filename = "http://Awebsite.com/image.php?size=large&&img=TMOV3"; 
 $size = getimagesize($filename);
 $fp = fopen($filename,"rb");     

 if ($size && $fp) {
 echo header("Content-type: {$size['mime']}");
  fpassthru($fp);
  exit;
} else {
  // error
}

I can see the ext in there but I get tons of gobaldy gooke in there with it is there a way to just grab the ext ?

can this not be done with a url like the above then ?

Have you seen the manual page for getimagesize?
Try something like:

$filename = "http://Awebsite.com/image.php?size=large&&img=TMOV3"; 
 $size = getimagesize($filename);
 if ($size) {
 switch ($size[2]) {
     case 1:
          $ext=".gif";
          break;
     case 2:
          $ext=".jpg";
          break;
//add cases as in getimagesize manual
  }//end of switch
} else {
  // error
}

Ok no laughing 🙂

This is what I have come up with (doesn't work of course)

<?php
       $img = $_GET['img'];
	   $size = $_GET['size'];

$filename1 = "http://awebsite.com/image.php?size=$size&img=$img";  

 $size1 = getimagesize($filename1); 
 if ($size1) { 
 switch ($size1[2]) { 
     case 1: 
          $myext=".gif"; 
          break; 
     case 2: 
          $myext=".jpg"; 
          break; 
     case 3:
		  $myext =".png";
		  break;
	case 4:
		  $myext =".swf";
		  break;
	case 5:
		  $myext =".psd";
		  break;
	case 6:
		  $myext =".bmp";
		  break;
//add cases as in getimagesize manual 
  }//end of switch 
} else { 
  // error 
}  

if($size == "small") {
	   $filename = 'images/thumb_$img$myext';
	   }elseif($size == "large"){
	   $filename = 'images/$img$myext';
	   }

if (file_exists($filename)) {
   // We have the image localy use it <--[
// Dont need to do anything here 
$filen = $filename;
echo "it exists !";
} else {
echo "it does not size = $size and img = $img ext = $myext";
   // We Dont have the Image Go Get it ]-->
    if($size == "small") {
	   $filenname = 'http://awebsite.com/image.php?size=small&img=$img';
$src = fopen($filenname,"r");     

if ($src) 
{ 
$dst = fopen("images/thumb_$img$myext","w");         

 while(!feof($src)) 
 { 
  fwrite($dst,fread($src,1024)); 
}         

fclose($src);     

fclose($dst); 
$filen = "images/thumb_$img$myext";
}
	   }elseif($size == "large"){

   $filenname = 'http://awebsite.com/image.php?size=large&img=$img';
    $src = fopen($filenname,"r");     
if ($src) 
{ 
$dst = fopen("images/$img$myext","w");         

 while(!feof($src)) 
 { 
  fwrite($dst,fread($src,1024)); 
}         

fclose($src);     

fclose($dst);
$filen =  "images/$img$myext";
}
	   }
}

$size2 = getimagesize($filen);
$fp=fopen($filen, "rb");
if ($size2 && $fp) {
  header("Content-type: {$size2['mime']}");
  fpassthru($fp);
  exit;
} else {
  // error
  echo "<p>error and filename = $filen</p>";
}

?>

Is there any error there?
What happens if you enter manually http://awebsite.com/image.php?size=xxxx&img=some_image into your browser? Does it return a picture?

All fixed 🙂

it was $size2 causing the problem it was empty
