PHP Listing Non Existent Error

[JesseElser]

I'm getting an error and no matter how many people look at the code no one can figure out why.

 

The error I'm getting is:

 

Parse error: syntax error, unexpected '$ratio_orig' (T_VARIABLE) in /home/jollyrogerpcs/public_html/img/gallery/thumbnail.php on line 23

 

The code is:

 

// thumb width

$square = 150;

$large = 200;

$small = 100;

////////////////////////////////////////////////////////////////////////////////// square

if( isset($_GET["img"]) &&  ( $_GET["type"] == "square" || $_GET["type"] == "" ) ){

// thumb size

$thumb_width = $square;

$thumb_height = $square;

// align

$align = $_GET["align"];

// image source

$imgSrc = $_GET["img"];

$imgExt = substr($imgSrc,-3);

// image extension

if($imgExt == "jpg"){ $myImage = imagecreatefromjpeg($imgSrc); }

if($imgExt == "gif"){ $myImage = imagecreatefromgif($imgSrc); }

if($imgExt == "png"){ $myImage = imagecreatefrompng($imgSrc); }

// getting the image dimensions 

list($width_orig, $height_orig) = getimagesize($imgSrc);  

// ratio

$ratio_orig = $width_orig/$height_orig;

// landscape or portrait?

if ($thumb_width/$thumb_height > $ratio_orig) {

$new_height = $thumb_width/$ratio_orig;

$new_width = $thumb_width;

} else {

$new_width = $thumb_height*$ratio_orig;

$new_height = $thumb_height;

}

// middle

}

 

Every line has the required semicolons. All brackets are properly closed. I have zero clue why that error even exists and I had this posted on another site and no one could figure it out.

 

If it helps the script is from http://1stwebmagazine.com/generate-thumbnail-on-the-fly-with-php

Whats the "*" for?

Would have been nice if you pointed out where line 23 was.

[mac_gyver]

the code as posted above doesn't produce that error.

 

it's likely that something about how it was published, with the highlighting, and how you copied it into your file or what you used as an editor got some encoded characters or the edits you did introduced a curly/smart-quote instead of a straight-quote.

 

i would copy/paste the above into a completely new file and try it.

Is there not a way to edit?

[ginerjm]

You have some extra hidden chars at the end of this line right before $ratio_orig is ref'ed

 

list($width_orig, $height_orig) = getimagesize($imgSrc);

list($width_orig, $height_orig) = getimagesize($imgSrc);

Removed all of the extra characters that show as blank spaces. Error code is now changing lines which i assume is more special characters. Do you have any suggestions on how to easily find any of these special chars?

[ginerjm]

Highlight the entire script and look for colored areas with no visible chars in them

Got them all removed and now there are no errors. Oddly enough it's a blank page now and not making thumbnails still but it's progress lol.
