的file_get_contents给我未能打开流 [英] file_get_contents gives me failed to open stream

问题描述

我有简单的CI（codeIgniter）code。我想要做的是：当我输入图片的路径textarea的，PHP下载的每一张图片到我的服务器，并给他们的文件名，但我有这些错误：

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

下面是我的CI code：

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);

它所做的仅仅是下载并为第一和第二档最后的文件给我的错误的

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

请不要给我其他方面的建议喜欢使用的fopen卷曲。我认为这是正确的做法，因为PHP下载LAST文件成功。请帮我解决我的问题。

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

推荐答案

我不知道为什么发生问题，但这里是code，它固定它，这要归功于NikiC谁发现了witespace是问题，我固定它。

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.

这code不起作用的

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);

这是工作code 的

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;}
    }
