Question

I have simple CI (CodeIgniter) code. what I want to do is: when I enter the pictures path to textarea, php downloaded each picture to my server and gave them filenames, but I have these errors:

Message: file_get_contents(http://geosmiley.ge/Upload/Product/42/1.jpg ) [function.file-get-contents]: failed to open stream: Invalid argument

Message: file_get_contents(http://geosmiley.ge/Upload/Product/42/2.jpg ) [function.file-get-contents]: failed to open stream: Invalid argument

Here is my CI code:

$image = explode("\n", $_POST['images']);
for ($i = 0; $i < count($image); $i++){
    if (substr($image[$i], 0, strlen($this->host) - 1) != $this->host){
        file_put_contents('images/'.$title_url.'_'.$i.'.jpg', file_get_contents($image[$i]));
        $image[$i] = $this->host.'/images/'.$title_url.'_'.$i.'.jpg';                                
    }
}
$poster = $image[0];
$images = implode("\n", $image);

What it does is simply downloads last file and for first and second files gives me that error

and please don’t give me other advice like using cURL of fopen. I think that it is correct way because php downloads LAST FILE successfully. Please help me to solve my problem

I don’t know Why the problem happened but here is the code that fixed it, thanks to “NikiC” who found out that witespace ” ” was the problem, I fixed it.

This Code doesn’t work

$image = explode("\n", $_POST['images']);
for ($i = 0; $i < count($image); $i++){
    if (substr($image[$i], 0, strlen($this->host) - 1) != $this->host){
        file_put_contents('images/'.$title_url.'_'.$i.'.jpg', file_get_contents($image[$i]));
        $image[$i] = $this->host.'/images/'.$title_url.'_'.$i.'.jpg';                                
    }
}
$poster = $image[0];
$images = implode("\n", $image);

This is working code

$image = explode("\n", $_POST['images']);
for ($i = 0; $i < count($image); $i++){
    if (substr($image[$i], 0, strlen($this->host) - 1) != $this->host){
        if ($i < count($image)-1){
            $kk = substr($image[$i], 0, strlen($image[$i]) - 1);
        } else {
            $kk = $image[$i];
        }
        if ($this->download($kk, 'images/'.$title_url.'_'.$i.'.jpg')){
            $image[$i] = $this->host.'/images/'.$title_url.'_'.$i.'.jpg';
        }else{
            echo($image[$i]);
        }
    }
}

    public function download($url, $path){
        if (file_put_contents($path, file_get_contents($url))){return TRUE;}else{return FALSE;}
    }
