check to make sure writing to file was successful.

[denoteone]

I have a function to writes data I want to make sure it was successful.

 

my function:

function save_ini_file($filename,$content)
{
$File = "ini_files/". $filename . ".ini"; 

echo $File;
$Handle = fopen($File, 'w'); 
$info = $content; 
fwrite($Handle, $info); 
fclose($Handle);

  return true;
}

 

the if statement that calls the function.

if(!save_ini_file($serial,$data))
{
echo "did not write";
}else{
echo "did write";
}

 

the file is being created but I am getting the "did not write" echoed

If you want to make sure your function executes successfully you need to at least check what it is doing.

 

function save_ini_file($filename,$content)
{
  $File = "ini_files/". $filename . ".ini";
  if ($Handle = fopen($File, 'w')) {
    $info = $content;
    if (fwrite($Handle, $info)) {
      return true;
    }
    fclose($Handle);
  }
  return false;
}

 

Because there are several things that may go wrong within this function, you might also want to take look at having it throw exceptions.
