deleting a new line from file via an array

Spud_Nic

I've done a search and found the answer using a String, but I need to use an array! So I thought I'd post and see if anyone can help.

This is my code:

$ContactDataFile = "datafile.csv";  

		$aCompleteData = @file ($ContactDataFile);  

		$aCompleteData = array_reverse($aCompleteData); 		
		$MessageHolder = $aCompleteData[$Msg];				
		$aCompleteData = str_replace($MessageHolder, "", $aCompleteData);


	//Open up file to write back new data
	$OpenPointer = fopen($ContactDataFile, "w");
		//implode the array to a string
		$sAllData = implode("\n", $aCompleteData);
	fwrite($OpenPointer, $sAllData);
	fclose($OpenPointer);

Now this code works except for one vital problem, on the line with the str_replace, it needs to replace the string in $MessageHolder AND the following new line (\n). At the moment it leaves the new line behind!

I was thinking I could maybe use a substr function to delete the newline after the str_replace, but this isn't really the route I want to use, if it would indeed work!

Any help very much grateful
Cheers

what are you trying to do exactly? remove just one line of a CSV? I assume the variable $Msg is the line number that you want to remove:

$ContactDataFile = 'datafile.csv';
$aCompleteData = file ($ContactDataFile);
unset ($aCompleteData[$Msg]);

$OpenPointer = fopen ($ContactDataFile, 'w');
$sAllData = implode ("\n", $aCompleteData); 
fwrite ($OpenPointer, $sAllData);
fclose ($OpenPointer);

yeah thats exactly what I'm trying to do.

Thanks for the code using unset. I've looked it up in the manual and understand how it works.

Cheers for that.
