Hi. I use this function with the strings I'll be showing in tables to cut
strings too long without spaces.
To make it clear:
<table width="50"><tr><td><?=$str?></td></tr></table>
The table will be 50px width if $str isn't too long. Let's say:
$str="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
The table goes to hell.
So:
function cut_text($res,$long=15,$max=20){
if ($max<=$long){$max=$long+2;}
$ant="";
while ($res!=$ant){
$ant=$res;
$res=addslashes($res);
$res= preg_replace ("/(\w){".$max.",}/im","'.substr (\\0,0,$long).'
'.substr (\\0,$long,strlen('\\0')-$long).'",$res);
$res=" return '$res';";
$res=eval($res);
}
return $res;
}
For example:
$str="Hello Howwwwwwwwwwwww arrrrreeeeeee yyyooooooouuuuuu";
echo cut_text($str,7,10);
Results in:
Hello Howwwww wwwwwwww arrrrre eeeeee yyyoooo ooouuuuuu
The idea is: any word longer than 20 chars will split into a chunk of 15
and a chunk of 5. If you have a 45 chars string, it will leave you with 20,
20 and 5.
It works fine with simple text, but with characters like ", / , $, etc.
sometimes I have problems. I tried with quotemeta instead of addslashes but
the problem persists. Anyone have an idea?. If you want to test the code,
just try with
Testing \" quotes
Thanks in advance
