Can changing the file permissions (chmod) resolve file upload issues in PHP?

File upload issues in PHP can sometimes be resolved by changing the file permissions of the upload directory or the uploaded file itself. This can be done using the chmod function in PHP to set the appropriate permissions for the file or directory to allow PHP to write to it. 

// Change file permissions to allow write access
$filename = 'path/to/uploaded/file.ext';
$permissions = 0644; // Or any other appropriate permission value
if (chmod($filename, $permissions)) {
    echo 'File permissions changed successfully.';
} else {
    echo 'Failed to change file permissions.';
}
