Php function mysql_query

[unlishema.wolf]

Well it is the time of the year I refresh myself on php again. I am wanting to make a function to connect to the mysql database, run the query, and return the result. However, I also wish to add in a way to get the mysql error if something messes up (for debugging of course).

 

Here is what I have so far:

<?php
$mysql_test_server="localhost";
$mysql_test_username="username";
$mysql_test_password="password";
$mysql_test_database="database";

function mysql_test_query($mysql_test_query, $mysql_test_close=true) {
	mysql_connect($mysql_test_server,$mysql_test_username,$mysql_test_password);
	mysql_select_db($mysql_test_database);
	$mysql_test_result = mysql_query($mysql_test_query);
	if ($mysql_test_close) {
		mysql_close();
	}
	return $mysql_test_result;
}

$result = mysql_test_query("SELECT * FROM people") or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
	echo "First Name: ".$row['first_name']."</ br>";
	echo "Last Name: ".$row['last_name']."</ br>";
}
?>

I forgot to mention I have attempted the following without any working results.

<?php
$mysql_test_server="localhost";
$mysql_test_username="username";
$mysql_test_password="password";
$mysql_test_database="database";

function usql_query($mysql_test_query, $mysql_test_close=true) {
	mysql_connect($mysql_test_server,$mysql_test_username,$mysql_test_password) or return false;
	mysql_select_db($mysql_test_database) or return false;
	$mysql_test_result = mysql_query($mysql_test_query) or return false;
	if ($mysql_test_close) {
		mysql_close() or return false;
	}
	return $mysql_test_result;
}

$result = usql_query("SELECT * FROM people") or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
	echo "First Name: ".$row['first_name']."</ br>";
	echo "Last Name: ".$row['last_name']."</ br>";
}
?>

However, after reading up on the php functions page I am going to test the following once I get my localhost back up and running.

<?php
$mysql_test_server="localhost";
$mysql_test_username="username";
$mysql_test_password="password";
$mysql_test_database="database";

function usql_query($mysql_test_query, $mysql_test_close=true) {
	$mysql_test_conected = mysql_connect($mysql_test_server,$mysql_test_username,$mysql_test_password);
	if(!$mysql_test_conected) {
		return false;
	}
	if(!mysql_select_db($mysql_test_database)) {
		return false;
	}
	$mysql_test_result = mysql_query($mysql_test_query);
	if(!$mysql_test_result) {
		return false;
	}
	if ($mysql_test_close) {
		if(!mysql_close()) {
			return false;
		}
	}
	return $mysql_test_result;
}

$result = usql_query("SELECT * FROM people") or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
	echo "First Name: ".$row['first_name']."</ br>";
	echo "Last Name: ".$row['last_name']."</ br>";
}
?>

Sorry for double post. I waited to long and can't edit the first post.

The following code allows you to call one function and run a mysql query without having to leave a mysql connection open or opening it every time. It will open the connection, select the database, run the query, and then close the connection if you wish so.

 

Notice: If a mysql_error() occurs it will not close the connection.

<?php
$mysql_test_server="localhost";
$mysql_test_username="username";
$mysql_test_password="password";
$mysql_test_database="database";

function mysql_test_query($mysql_test_query, $mysql_test_close=true) {
	global $mysql_test_server,$mysql_test_username,$mysql_test_password,$mysql_test_database;
	$mysql_test_conected = mysql_connect($mysql_test_server,$mysql_test_username,$mysql_test_password);
	if(!$mysql_test_conected) {
		return false;
	}
	if(!mysql_select_db($mysql_test_database)) {
		return false;
	}
	$mysql_test_result = mysql_query($mysql_test_query);
	if(!$mysql_test_result) {
		return false;
	}
	if ($mysql_test_close) {
		if(!mysql_close()) {
			return false;
		}
	}
	return $mysql_test_result;
}

$result = mysql_test_query("SELECT * FROM people") or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
    echo "First Name: ".$row['first_name']."</ br>";
    echo "Last Name: ".$row['last_name']."</ br>";
}
?>

Sorry for the third post just wanted to post the solution for my problem for anybody in the future.
