This is a little function to split a string into shorter strings with max lenght $n in such way,
that it don't split words (it search for spaces), it's usefull for articles or sth.
Result is put in $ttab variable, and function result is number of "pages".
<?php
function divide_text($text, $n, &$ttab) {
$ttab = array();
$l = strlen($text); // text length
$cb = 0; //copy begin from..
$p = 0; // parts
if ($l <= $n) {
$ttab[0] = $text;
return 1;
} else {
$ctrl = 1;
while(((($p-1) * $n) < $l) && ($ctrl < 100)) {
$crtl++; // control variable, to protect from infinite loops
$tmp = substr($text, $cb, $n);
// we're looking for last space in substring
$lastpos = strrpos($tmp," ");
if ( (is_bool($lastbool) && !$lastpos) || ( $l - $cb <= $n)) {
$ttab[$p] = $tmp;
} else {
$tmpgood = trim(substr($tmp, 0,$lastpos)); // if they were another spaces at the end..
$ttab[$p] = $tmpgood;
$cb += $lastpos + 1 ;
}; // if
$p++;
}; //for
return $p;
}; // if
} // divide text
?>
