Manipulating files

[teguh123]

Hi,

Can anyone shows me a code on how to:

Put an array into a text file

Retrieve an array from a text file

The text file contains a bunch of string, one per line.

I think it's pretty simple. But every time I write my own code I discovered an even more elegant code written by true expert.

Thanks,

Teguh

The text file contains a bunch of string, one per line.

So each element of the array corresponds to a line in the file?

Put an array into a text file

Under the assumption of one element per line, you could either use a simple loop or [man]implode/man.

Retrieve an array from a text file

Again under the assumption, you would use [man]file/man.

But every time I write my own code I discovered an even more elegant code written by true expert.

Post your own code. Perhaps you are an expert, but don't know it :p

function colToFile($ar, $filename)
{
	$whattoput=implode  ("\n",$ar);
	$handle = fopen($filename, "w");
	fwrite ($handle, $whattoput);
	fclose  ($handle);
}

function fileToCol($filename)
{
	$data=file_get_contents($filename);
	$data=explode ("\n",$data);
	return $data;
}

Yeah, it looks like you pretty much got it, though you could consider using [man]file_put_contents/man, and of course fileToCol() could be implemented with [man]file/man.
