Hi everyone,
I have modified textWrap(); this one works just fine (the last one had a buggy regular expression!)
and also gives you the chance to choose the line separator (3rd param).
Enjoy :)
<?php
function textWrap($text, $size, $separator="\\r\\n" ) {
$new_text = '';
$text_1 = explode('>',$text);
$sizeof = sizeof($text_1);
$remain = $size;
for ($i=0; $i<$sizeof; ++$i) {
$text_2 = explode('<',$text_1[$i]);
if (!empty($text_2[0])){
$perl = '/([^\\n\\r .]{'. $remain .',})/i';
$possibly_splitted= preg_replace( $perl, '$1'.$separator, $text_2[0] );
$splitted = explode($separator,$possibly_splitted);
$remain -= strlen($splitted[0]);
if($remain<=0) $remain = $size;
$new_text .= $possibly_splitted;
}
if (!empty($text_2[1])) $new_text .= '<' . $text_2[1] . '>';
}
return $new_text;
}
?>
