Enahncement to mysql_query php function.

I have extended mysql_query function to have more flexibility. It is a php file say "run_query.php". Include this file in your php application. To use this file follow these steps.
1) Create a table in mysql with the following structure.
CREATE TABLE `errorlog`
( `query` varchar(5000) default NULL,
`error` varchar(5000) default NULL )

2) Create a php file and paste following code. Save the file (say file name is run_query.php).

< ? php
function mysql_query_($query)
{ // Paste here code to connect to mysql database.
$username='root';
$password='';
$host='localhost';
$db_name="xyz";
$conn1=mysql_connect($host,$username,$password) or die("Unable to connect to mysql server");
$select1=mysql_select_db("$db_name",$conn1) or die("Unable to connect to mysql database");
$curdate = date("d-m-Y H:i:s");
if(mysql_query($query) == true) // The queri is fired and checked.
{
if(substr(strtoupper($query),0,6) == 'INSERT' substr(strtoupper($query),0,5) == 'UPDATE' substr(strtoupper($query),0,5) == 'DELETE') // The query is checked for Insert/Update/Delete
{
$fp=fopen("trans.sql","a"); //If query is type of Insert/Update/Delete then it will store the query into trans.sql file.
if($fp==null)
{
die("File cannot be opened. Try again !!!");
}
$printline = "/* $curdate : */ $query ;";
fprintf($fp,"\r\n%s",$printline);
fclose($fp);
return true;
}
else
{
return mysql_query($query);
}
}
else
{
$error = mysql_error();
$error = addslashes($error);
$query = addslashes($query);
mysql_query("insert into errorlog values('$query','$error')");
return false;
}
}

3) Include this file in your any php application. (Command to include file : )
4) Use mysql_query_ function instead of mysql_query function.
e.g.
/*< ? php $query = "select * from employee";
$result = mysql_query _($query)
? >
*/
Advantages.

1. You can log query and error in your database table (errorlog).
2. A sql file created/appendended whenever any Data manipulation query is fired. So you can have a complete transaction log in query format.
3. This sql "trans.sql" file will help you in "point in time recovery" in case of the database is crashed.
