new file incrementing

[luminous]

I've got a script that generates a a file based on data that is being updated in the database. For the sake of an example everytime the database is updated, a new file is created with the new data.  Is it possible with fopen or another function to create new files with different file names from scratch?

Are you asking if you can create blank files? Using fopen will create a file that does not exist when using write or append mode.

 

$file = fopen('/files/does_not_exist.txt', 'w');

Sorry to be a pain perhaps you can help me further as this problem is slightly more puzzling then i first thought. Basically I run a script that makes a CSV file. Once created it returns the CSV file in the form of a header:

 

	if(!is_null($file_name)) $file_name = date('Y-m-d');
	// set content type and file name then output csv content
	header("Content-type: application/octet-stream");
	header("Content-Disposition: attachment; filename=\"$file_name.csv\"");
	echo $csv;

 

but I just want it to save the CSV file to a disclosed location. I'm using FOPEN at the moment but this is creating a blank file:

 

		if(is_null($file_name)) $file_name = date('Y-m-d');
	// set content type and file name then output csv content
	$date = date('M-Y');
	$orderDate = 'Orders '.$date;

	if(!file_exists($orderDate))
		{
			mkdir($orderDate);
			fopen ($orderDate.'/'.$file_name.'.csv', 'x');
		}else{

			fopen ($orderDate.'/'.$file_name.'.csv', 'x');
		}

 

How could I resolve this?

fopen creates a blank file and returns an object you can use with fread or fwrite.

 

if(is_null($file_name)) $file_name = date('Y-m-d');

// set content type and file name then output csv content


$date = date('M-Y');

$orderDate = 'Orders '.$date;


if(!is_dir($orderDate))
{
mkdir($orderDate);
}

$file = fopen ($orderDate.'/'.$file_name.'.csv', 'x');

fwrite($file, $data); //$data is a string of what you want in the file.

 

I also changed your directory check to use is_dir instead of file_exists
