[RESOLVED] Extra element in returned array of explode()?

[david8787]

The following code prints 5 lines why is it not 4?

<?php
	header('Content-Type: text/plain');
	$myString = "line1\nline2\nline3\nline4\n";
	$myArray = explode("\n", $myString);

while(list($lineNum, $line) = each($myArray))
{
	echo ($lineNum+1) . ": $line\n";
}
?>

Because there are five pieces of data when you split that string on every new line character; four of the five contain text, while the fifth is an empty string.

If you want to trim off a line break at the end of the string, [man]rtrim/man it before you explode() it.
