New do_sql.php

I've rewritten my do_sql.php code to work with the Pear DB library and refactored everything while I was at it:

<?php

require "DB.php";

include("read_config.php");

function sql_doozer($db, $sql, $is_query, $debug){

	if($debug == true){ print $sql; }

	# Set up the reply array

	(array) $reply;

	# Get our database connection details from the INI config file

	(array) $config = read_config($db.".ini");

	if($debug == true) { print_r($config); }

	$conf = $config["connection_parameters"];

	# Build the connection URL
	
	$db_url = $conf["type"]."://".$conf["user"].":".$conf["passwd"].
	"@".$conf["host"]."/".$conf["db"];

	if($debug == true){ print $db_url; }

	# Create our connection

	$connection = DB::Connect($db_url);

	if(DB::isError($connection)){

		$reply["status"] = false;

		$reply["message"] = $connection->getMessage();		

		return($reply);

		}

	(array) $reply["rows"];

	# Do the query

	$cursor = $connection->query($sql);

	if(DB::isError($cursor)){

		$reply["status"] = false;

		$reply["message"] = $cursor->getMessage()." - ".$sql;		

		return($reply);

		}

	$count = 0;

	# If this is an SQL query get the results back

	if($is_query == true){

		$reply["num_of_rows"] = $cursor->numRows();

		if(DB::isError($cursor)){

			$reply["status"] = false;

			$reply["message"] = $cursor->getMessage();

		
			return($reply);

			}

		while($this_row = $cursor->fetchRow(DB_FETCHMODE_ASSOC)){

			if(DB::isError($this_row)){

				$reply["status"] = false;

				$reply["message"] = $this_row->getMessage();		

				return($reply);

				}

			$reply["rows"][$count] = $this_row;

			$count++;

			}

		}

	if($debug == true){ print_r($reply["rows"]); }

	$reply["first_row"] = $reply["rows"][0];

	$reply["status"] = true;

	$reply["message"] = "OK";

	return($reply);

	}

function is_query($sql){

	# Check to see if our SQL is an insert or update statement

	$sql_list = explode(" ",$sql);

	if((strtolower($sql_list[0]) == "insert") 
	or (strtolower($sql_list[0]) == "update") 
	or (strtolower($sql_list[0]) == "create") 
	or (strtolower($sql_list[0]) == "alter")){

		return(false);

		}

	return(true);

	}

function do_sql($db, $sql, $debug){

	$is_query = is_query($sql);

	return(sql_doozer($db, $sql, $is_query, $debug));

	}

function do_sql_query($db, $sql, $debug){

        return(sql_doozer($db, $sql, true, $debug));

        }

function do_sql_insert($db, $sql, $debug){

        return(sql_doozer($db, $sql, false, $debug));

        }

function do_sql_update($db, $sql, $debug){

        return(sql_doozer($db, $sql, false, $debug));

        }

?>
