I'm using a pre-written script found at 1st Web Magazine - Generate Thumbnail On The Fly.
I copied the script over to my server, but it's giving me the following error: Parse error: syntax error, unexpected '$ratio_orig' (T_VARIABLE) in /storage/emulated/legacy/www/jollyroger/jollyroger/img/gallery_temp/thumbnail.php on line 23
I've went through the code and I cannot spot any actual errors. Everything seems to be in order.
Could someone take a look at this code and tell me if I am overlooking something? From what I can gather it seems that something in the list() function is throwing off the variables.
This is the code actually in my file:
<?php
// 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
$x_mid = $new_width/2;
$y_mid = $new_height/2;
// create new image
$process = imagecreatetruecolor(round($new_width), round($new_height));
imagecopyresampled($process, $myImage, 0, 0, 0, 0, $new_width, $new_height, $width_orig, $height_orig);

Even this line in my editor is highlighted red which indicates an error, but since the variable is triggering a php error this one has not shown up in any logs yet. Looking over this line I cannot spot anything wrong at all.
if(isset($_GET["img"]) && ($_GET["type"] == "large" || $_GET["type"] == "small" ) ){
I copied the code direct from the website so I'm at a loss as to why it is not working. As I said I've looked it over and everything seems to be in order, so I'm at a complete loss.
Also this script is in the same directory as my image files. My test url looks like so: http://localhost:8080/jollyroger/jollyroger/img/gallery_temp/thumbnail.php?img=1959523_1501438810115481_7515978806557307096_n.jpg
