Php - unlink throws error: resource is temporarily unavailable

Question

Here is the code snippet:

public function uploadPhoto(){
    $filename = '../storage/temp/image.jpg';  
    file_put_contents($filename,file_get_contents('http://example.com/image.jpg'));
    $photoService->uploadPhoto($filename);
    echo("If file exists: ".file_exists($filename));
    unlink($filename);
}

I am trying to do the following:

• Get the photo from the URL and save it in a temporary folder on my server. It works great. An image file is created and echoed If file exists: 1when echo("If file exists: ".file_exists('../storage/temp/image.jpg'));.
• Pass this file to another function that uploads the file to the Amazon s3 trash. The file is stored in my s3 statement.
• Delete the photo saved in the temp folder. This does not work! I get an error message:

unlink (../storage/temp/image.jpg): the resource is temporarily unavailable

If I use rename($filename,'../storage/temp/renimage.jpg');instead unlink($filename);, I get an error:

rename (../storage/temp/image.jpg,../storage/temp/renimage.jpg): , . (: 32)

$photoService->uploadPhoto($filename);, .

Answer 5

The unlink method returns bool, so you can build a loop with some wait () and limit the number of attempts to wait for processes to complete.

Additionally, add "@" in the disabled link to hide the access error.

Throw another error / exception if the number of attempts is reached.
