Hi Guys,


I have the latest version of Uniserver ZeroXL installed and running. I've transferred across from XAMPP and I wanted something lighter and less bloated.


The only issue I'm having is that one of my PHP scripts relies on curl and GD to pull images from my IP camera, sadly I cannot get this to work using Uniserver - it works fine with the default install of XAMPP.


The message displayed is attached, I've also ensured that both curl and GD are ticked under PHP modules.


Any help getting this resolved would be greatly appreciated, I've spent hours googling around and trying various things with no luck...


I also tried the following code in check.php and it just displays a blank page.

// is curl installed?
if (!function_exists('curl_init')){ 
die('CURL is not installed!');

// create a new curl resource
$ch = curl_init();
echo "OK";

The above example code will not work because you are using short PHP tags Uniform Server defaults to using full PHP tags.


The following examples show curl and gd operation on a default installation 11_7_4_ZeroXI


curl example save as file z2.php

$image_url = "http://www.uniformserver.com/ZeroXI_documentation/common/images/us_zero_logo.png";
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $image_url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

// Getting binary data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

$image = curl_exec($ch);

// output to browser
header("Content-type: image/png");
print $image;

gd example save as file z3.php

    header("content-type: image/png");
    $src_img = imagecreatefrompng("images/logo.png");
    $srcsize = getimagesize("images/logo.png");
    $dest_x = $srcsize[0] / 2;
    $dest_y = $srcsize[1] / 2;
    $dst_img = imagecreatetruecolor($dest_x, $dest_y);

    imagecopyresized($dst_img, $src_img, 0, 0, 0, 0, $dest_x, $dest_y, $srcsize[0], $srcsize[1]);

To run type http://localhost/z2.php and http://localhost/z3.php


All the best
