preg_replace with multidimentional arrays retrieved from a mysql database

[scarhand]

here is my code, first of all:

 

<?php

$smileys_query = "SELECT * FROM smileys";
$smileys_result = mysql_query($smileys_query);

while($row = mysql_fetch_assoc($smileys_result))
{
  $smileytxt[] = $row['word'];
  $smileyimg[] = $row['image'];
}

$censors_query = "SELECT * FROM censors";
$censors_result = mysql_query($censors_query);

while($row = mysql_fetch_assoc($censors_result))
{
  $censorword[] = $row['word'];
  $censorreplace[] = $row['censor'];
}

echo preg_replace(array($smileytxt, $censorword), array($smileyimg, $censorreplace), $message);

?>

 

now as you can see i want all the results from the smileys and censors tables to go into arrays....i might have this wrong but that is not the biggest problem here. the problem is the fact that i have no clue how to make it so that delimiters are automatically put in place once they are retreived from the mysql database...any help would be greatly appreciated.
