[RESOLVED] Problem with the str_replace function

[kozmk]

hi there i'm using this code

$resulttags = mysql_query("SELECT * FROM sectags");
while( $rowtags = mysql_fetch_array($resulttags)){
$org = $rowtags['tag'];
$rpc = "<a href='?tag=".$org."'>$org</a>";
$edited = str_replace($org, $rpc, $edited);
}

now the problem is that after it replaces a word with the link it also changes the link because in the link is the original variable that he has to be changed.

anyone know how to resolve this?

thx

ehm..

Not sure what you are trying to achieve.. Wouldn't this do what you want:

$resulttags = mysql_query("SELECT * FROM sectags");
while( $rowtags = mysql_fetch_array($resulttags))
  {
  $rpc = "<a href='?tag=".$rowtags['tag']."'>".$rpc."</a>";
  }

thx for the fast reply, but this wouldent do it.
tis code needs to find words in a large string and then replace these words with a link

ah, ok so the example you gave was a bit off 😃

you need to use a regular expression for this like [man]preg_replace[/man]; unfortunately my regular expression skils are horrible, and I cannot make a usefull regexp. suggestion, i am afraid.

already found the solution

$query = mysql_query("SELECT DISTINCT tag FROM sectags");
while ($row = mysql_fetch_assoc($query))
{
    $tag    = $row['tag']; 
    $link   = "<a href=\"?tag={$tag}\">{$tag}</a>";
    $edited = str_replace($tag, $link, $edited); 
}
