First and last line

[hendry]

I would like to grab the first and last line of a form's textarea with
PHP's PCRE functionality. Anyone have a recipe to do that? Or have a
better suggestion?

Assuming the lines are separated by \n, you can simply do:

$lines = explode("\n", $text);
$firstLine = $lines[0];
$lastLine = array_pop($lines);

Hello!

Assuming the lines are separated by \n, you can simply do:

$lines = explode("\n", $text);
$firstLine = $lines[0];
$lastLine = array_pop($lines);

Be careful with array_pop() here!
If $lines is used later perhaps the missing line is needed.
You should either use

$firstLine = $lines[0];
$lastLine = $lines[count($lines)-1];

or

$firstLine = array_shift($lines);
$lastLine = array_pop($lines);

Greetings,

The spec says that, for both the POST and GET methods, lines
are separated by CRLF pairs.
