               mysql_connect ($dbhost, $dbuser, $dbpass);
               mysql_select_db ($dbname) or die ( mysql_error ());
               $query = "SELECT part_number FROM parts_db WHERE part_number RLIKE '".$_POST['txt_search']."'ORDER BY part_number ASC";
               $result = mysql_query ($query) or die ( mysql_error () );

return it:
[code]$prt_num_found =$row['part_number'];
     }
    return $prt_num_found;
}[/code]
The you can do this:
[code]if(search_like() == "somthing")
{
    //do something if true;
}
else
{
    //do something else if not true.
}[/code]

Use the [a href=\"http://us3.php.net/return\" target=\"_blank\"]return()[/a] statement:
[code]<?php
function search_like()
{
               include ('includes/dbconfig.php');
               mysql_connect ($dbhost, $dbuser, $dbpass);
               mysql_select_db ($dbname) or die ( mysql_error ());
               $query = "SELECT part_number FROM parts_db WHERE part_number RLIKE '".$_POST['txt_search']."'ORDER BY part_number ASC";
               $result = mysql_query ($query) or die ( mysql_error () );            
     while($row=mysql_fetch_array($result)) {
               echo "<option value='{$row["part_number"]}'>{$row["part_number"]}</option>";
               $prt_num_found =$row['part_number'];
     }      
     return($prt_num_found);
}

$pnf = search_like();
echo $pnf;
?>[/code]
