custom db query, and db prep functions

here’s a few functions that are required by some of my code / functions.

make_db_connection

function make_db_connection($conn_name, $conn_sql)
{

global $site_access, $database_site_access;

$covert_this_str = "global $" . $conn_name . " ;";
eval($covert_this_str);
$covert_this_str = "$" . $conn_name . "= mysql_query($conn_sql,$site_access ) or die(mysql_error());";//report_error(‘002′,’" . addslashes($conn_sql) . "’));";
//echo $conn_sql."<br />";
eval($covert_this_str);
// addKill($conn_name);
}

fixForDB

function fixForDB($item,$nonEmpty=0){

$item=trim($item);
if(empty($item)){

$item=$nonEmpty;

}

if(isNaN($item)){
$item=”‘”.addslashes($item).”‘”;
}

return $item;
}

isNaN
this isn’t a function of mine. I found it on the php.net manual site. if you wrote it, please let me know so i can give proper credit

function isNaN( $var ) {
return !ereg (“^[-]?[0-9]+([.][0-9]+)?$”, $var);
}
