In index.php I have this code:
<?php
$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$) |(\.Gif$)"; //valid image extensions
$files = array();
$curimage=0;
if($handle = opendir("http://newsxpressmedia.com/files/radar-simulation-files")) {
while(false !== ($file = readdir($handle))){
if(eregi($pattern, $file)){ //if this file is a valid image
//Output it as a JavaScript array element
$files[] = $file;
$curimage++;
}
}
closedir($handle);
}
?>

My host website is ipage.com In the filemanager on ipage.com i see the directory files/radar-simulation-files from the root directory.
I'm using netbeans 8.0.1 and xampp to run localhost apache server.
In NetBeans when I click the run button it's going to this location:
http://localhost/PhpProject2/index.php
And there, above the first image I see:
Warning: opendir(http://newsxpressmedia.com/files/radar-simulation-files): failed to open dir: not implemented in C:\xampp\htdocs\PhpProject2\index.php on line 5
What I want to do is to get a list of all images in the directory files/radar-simulation-files
EDIT
This is the code i tried now:
<?php
$username = 'my domain name';
$password = 'my pass';
$basepath = 'domains/newsxpressmedia.com/public_html/';
$handle = opendir("ftp://{$username}:{$password}@ftp.ipage.com/{$basepath}files/radar-simulation-files");
//$imgdir = 'images/'; //Pick your folder
$allowed_types = array('png','jpg','jpeg','gif'); //Allowed types of files
//$dimg = opendir($imgdir);//Open directory
while($imgfile = eaddir(handle))
{
if( in_array(strtolower(substr($imgfile,-3)),$allowed_types) OR
in_array(strtolower(substr($imgfile,-4)),$allowed_types) )
/*If the file is an image add it to the array*/
{$a_img[] = $imgfile;}
}
echo "<ul>";
$totimg = count($a_img); //The total count of all the images
//Echo out the images and their paths incased in an li.
for($x=0; $x < $totimg; $x++){echo "<li><img src='" . $imgdir . $a_img[$x] . "' /></li>";}
echo "</ul>";
?>

I have uploaded the file to my host domain ipage.com filemanager I'm then browsing to:
It start counting back the timer but then stop on 1
Then i'm doing on the website: Inspect element And in the console i see error:
Uncaught TypeError: Cannot read property 'length' of null
On line 23
Something is wrong with the php code that should get all the images files and put them in the array.
