how do I remove line breaks from string

[Anon]

Ok, Im really stuck here.

Heres what Ive got from the top.

A textarea used for entering text into a database.

Im using $text=nl2br($text); along with $text=addslashes($text); before insertion to maintian line breaks etc.

Ive constructed a search engine (too big to display here) which works fine, it displays the text exactly as it went in.

Finally, Im building abstracts from the text using the sentence containing the search parameter and displaying those sentences to the user.

    If(($value!=="")&&($search=="")){echo "<strong>Extract:</strong><br>\n";echo $solution;}
    else{
	 echo "<strong>Abstract:</strong><br>\n";
   $newsolution=explode("." , $solution); 
     $n=count($newsolution);
     for ($p=0; $p<$n-1;$p++)
     {
    $k=sizeof($rush);
    //echo $k;
        for($x=1; $x<count($rush); $x++)
	{
        if(ereg("^\\+", $rush))
           {
           $rush = ereg_replace("^\\+", "", $rush);
           }
        elseif(ereg("^\\-", $rush))
           {
           $rush = ereg_replace("^\\-", "", $rush);
           }
        if (eregi("($rush[$x])", $newsolution[$p])) {$mssg=$newsolution[$p].".".$mssg;}
        }
     }  
     $mssg=explode(".", $mssg);                 
     $mssg=array_unique($mssg);
     reset($mssg);
     //sort($mssg);
     for ($y=0;$y<count($mssg);$y++)
     {
     $nmssg=$nmssg . "....." . $mssg[$y];
   $nmssg=explode(".....", $nmssg);                 
     $nmssg=array_unique($nmssg);
   $nmssg=implode(".....", $nmssg);	   
     }
   if(!($nmssg)){echo $solution;}
   else{
     echo $nmssg;
   }
    unset($nmssg);unset($mssg);
    }

This last bit works but I cant find a way to remove line breaks ect..

for example...
this is line one.

this is line two.

should be ..
this is line one.
this is line two.

ive tried eregi_replace() with \n\r
and ive tried to the html version but no success any ideas any one?

Sorry to have wasted your time..... I think its the lack of sleep.

I was working on the wrong variable.....
the solution was
$solution = eregi_replace("<br />","",$solution);

again sorry to waste your time..

You might consider using str_replace instead. It's faster because it doesn't rely on regular expressions, and your search criteria, "<br />" is a simple pattern that doesn't require regular expressions.

Also, the preg_* family of functions are usually faster than the ereg functions. In http://www.php.net/manual/en/function.ereg.php it says:
"Note: preg_match(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to ereg()."
