Wordwrap nonproportional fonts! and exclude html tags!
If you have a problem with PHP' worwrap which you aren't able to give
arguments for NOT parsing through some string parts (like html codes,
which could be longer then ie.80 chars), here's how to do it.
This function, cuts words in $str longer then $cols long, and puts and $cut in
it. It escapes everything whitin "<>".
So "<longggggggggggggtext>" will not be cutted, and just
"longggggggggggggtext", will be cutted! :)
This one can also try to work with nonproportional fonts. Like Arial and Verdana, instead of only
fixed fonts.
$str = the string you want to process.
$cols = choose ie.80 for prop.fonts
choose ie.450 for non prop fonts
NOTE: $cols are not pixels!
$non_prop = choose "true" for arial,verdana etc.
false = fixed (courier)
$exclude1 = excludesystem, read the begin of this note. enter '<'
$exclude2 = enter '>'
function sheep_wordwrap($str,$cols,$non_prop,$cut,$exclude1,$exclude2){
$count=0;
$tagcount=0;
$str_len=strlen($str);
//$cut=" $cut ";
$calcwidth=0;
for ($i=1; $i<=$str_len;$i++){
$str_len=strlen($str);
if ($str[$i]==$exclude1)
$tagcount++;
elseif ($str[$i]==$exclude2){
if ($tagcount>0)
$tagcount--;
}
else{
if (($tagcount==0)){
if (($str[$i]==' ') || ($str[$i]=="\n"))
$calcwidth=0;
else{
if ($non_prop){
if (ereg("([QWOSDGCM#@m%w]+)",$str[$i],$matches))
$calcwidth=$calcwidth+7;
elseif (ereg("([I?\|()\"]+)",$str[$i],$matches))
$calcwidth=$calcwidth+4;
elseif (ereg("([i']+)",$str[$i],$matches))
$calcwidth=$calcwidth+2;
elseif (ereg("([!]+)",$str[$i],$matches))
$calcwidth=$calcwidth+3;
else{
$calcwidth=$calcwidth+5;
}
}
else{
$calcwidth++;
}
if ($calcwidth>$cols){
$str=substr($str,0,$i-1).$cut.substr($str,$i,$str_len-1);
$calcwidth=0;
}
}
}
}
}
return $str;
//moby rules at 5am! :)
