Spliiting By Paragraph

[Anon]

If I have a string $input which contains many paragraphs of text, how could I create a new string (eg. $intro) which contains only the first paragraph of $input?

Thanks

what you could do. supposing each new paragraph starts with a new line and an indent of 2 characters.

<?

$lines=explode("\n", $input);

$para1="";
$got=0;
$lineat=0;
while ( $got == 0 && $lineat < count($lines) )
{
if ( substr($lines[$lineat], 0, 2) == " " )
{
$got=1;
}
else
{
$para1.=$lines[$lineat]."\n";
$lineat++;
}
}

?>

Mark.
