file_put_contents不会保存文件

Question

Hi I'm trying to use PHP file_put_contents to save a raster file to my local drive. The raster file is acquired by curl request, the url link works perfectly fine if open with browser(file is downloadable), but the file_put_contents won't save anything to the folder. Below is my php pseudo code:

$ch = curl_init(working_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$save = curl_exec($ch); 
curl_close($ch);
file_put_contents($path_of_file, $save);

I have chmod to 777 and have the full write and read to the folder and the save path is correct.

Answer 1

Try this:

$save = file_get_contents($working_url);
file_put_contents($path_of_file, $save);

And please check:

• you can write the destination folder
• you have the right content in $save variable

Maybe provide us the URL to check it.
