Question

im having a odd problem os my website, i have a script that records all the searchs and insert those search words on database, the problem is that since search engine robots started sneaking around my website, they make my script to produce search keywords like “search keywords////////////////////////////////////////////////”
I want to strip that characteres ( ////////// ) before indexed on mysql.

This is what i have:

$search=htmlspecialchars($_GET['load']); 
$say=mysql_query("SELECT * FROM madvideo WHERE MATCH (baslik) AGAINST ('*$search*' IN BOOLEAN MODE)"); 
$saydim=mysql_num_rows($say);
$count = $saydim;
$page = !empty($_GET["page"]) ? intval($_GET["page"]) : 1;
$s = ($page-1)*$perpage;
$sayfasayisi=ceil($count/$perpage);
if(ayaral("Arananlar-Kaydet")=="1") {
$ekle=cevir($search);
@mysql_query("insert into tag (baslik,tr,tarih) values ('$search','$ekle',now()) "); }

The variable ” $search ” will call the search word, and i dont know whats the strip syntax i have to use to strip that nasty ///////// character.

EDIT: the code that creates the words is this:

$vtitle = str_replace("\r\n\r\n", ' ', $vtitle); 

$words = explode(' ', $vtitle); 

$k = count($words); 
$k3 = ceil($k/3); 

$new = array(); 
for ($i=0; $i<$k; $i+=$k3) { 
    $new[] = join(' ', array_slice($words,$i, $k3)); 
} 
$tag1 = $new[0]; 
$tag2 = $new[1]; 
$tag3 = $new[2];

Use MySQL TRIM function to remove from end of the string as follows:

TRIM(TRAILING '/' FROM <string>)

@mysql_query("insert into tag (baslik,tr,tarih) 
values (TRIM(TRAILING '/' FROM '$search'),'$ekle',now())")

To trim from both beginning and ending, use following

TRIM(BOTH '/' FROM <string>)

@mysql_query("insert into tag (baslik,tr,tarih) 
values (TRIM(BOTH '/' FROM '$search'),'$ekle',now())")

To remove all occurences of the string use REPLACE function as follows:

REPLACE(<string>, '/', '')

@mysql_query("insert into tag (baslik,tr,tarih) 
values (REPLACE('$search', '/',''),'$ekle',now())")

Hope it helps…
