使用PHP处理文件时出错

Question

Error Handling with files in PHP

$path = '/home/test/files/test.csv';
fopen($path, 'w')

Here I want add an error handling by throwing exceptions, on 'No file or directory is found' and 'No permission to create a file'.

I am using Zend Framework.

By using fopen with write mode, I can create a file. But how to handle it when corresponding folder is not there?
i.e if files folder is not present in root structure.

How to throw an exception when no permission is permitted for creating a file?

Something like this should get you started.

function createFile($filePath)
{
  $basePath = dirname($filePath);
  if (!is_dir($basePath)) {
    throw new Exception($basePath.' is an existing directory');
  }
  if (!is_writeable($filePath) {
    throw new Exception('can not write file to '.$filePath);
  }
  touch($filePath);
}

Then to call

try {
  createFile('path/to/file.csv');
} catch(Exception $e) {
  echo $e->getMessage();
}
