Untested code:
<?php
$text = ltrim($text); //Just in case a leading space gets in there...
//Convert Mac/PC/Unix newlines:
$text = str_replace("\r\n", "\n", $text);
$text = str_replace("\r", "\n", $text);
$paragraphs = explode("\n", $text);
$new_text = '';
while (list(, $paragraph) = each($paragraphs)){
for ($second_word_second_letter = 1; $second_word_second_letter <
count($paragraph) && $paragraph[$second_word_second_letter] != ' ';
$second_word_second_letter += 2){
//an empty body with no code on purpose. see above
}
$first_word_end = $second_word_second_letter - 2;
$first_word_end = max(0, $first_word_end);
$first_word = substr($text, 0, $first_word_end);
$rest = substr($text, $first_word_end + 1);
$first_word = str_replace(' ', '', $first_word);
$new_text .= trim("$first_word $rest") . "\n";
}
?>
I think I've avoided all the ways a blank paragraphs would get bogus
results, but...
