Hi there here is a little function i wrote to limit the number of lines in a string, i could not
find anything else like it out there
<?php
function lineLimiter ($string = "", $max_lines = 1) {
$string = ereg_replace("\n", "##", $string);
$totalLines = (substr_count($string, '##') + 1);
$string = strrev($string);
$stringLength = strlen($string);
while ($totalLines > $max_lines) {
$pos = 0;
$pos = strpos ( $string, "##") + 2;
//$pos = $pos - $stringLength;
$string = substr($string, $pos);
$totalLines--;
}
$string = strrev($string);
$string = ereg_replace("##", "\n", $string);
return $string;
}
?>
