Simple Alternating Row Color with PHP!

Tony Virelli — Thu, 23 Jun 2011 15:20:07 +0000

If you have ever do table data and want to alternate the row colors here is a super simple way to do that using PHP.

First you need to declare your variables. So since we are doing Alternating Colors I will use $ac as my var.

 $ac = 0; ?>

Then in your tag it is as simple as adding this code:

 echo ($ac++%2==0)?"#EBEBEB":"#FFFFFF"; ?>">

Another way you could do it is to declare a class:

 echo ($ac++%2==0)?"odd":"even"; ?>">

Update Your Website Copyright With Some Simple PHP

Tony Virelli — Fri, 26 Feb 2010 07:00:24 +0000

Ok, so every year web designers have the all dreaded task of updating the copyright on their designs. This isn’t so bad if you work for 1 company, but if you work for a design firm like I do and have tons of clients websites to update it can be a time eating task.

So to fix this problem I wrote this super small, super easy bit of code. It’s nothing special, but it gets the job done.


$startYear=2010; //Enter the starting year of the copyright.
if($startYear < date("Y")){
	echo $startYear."-".date("Y");
}else{
	echo $startYear;
}
?>

And for the function lovers


function updateCopyright($startYear){
	if($startYear < date("Y")){
		echo $startYear."-".date("Y");
	}else{
		echo $startYear;
	}
}
?>
//Usage: Copyright ©  echo updateCopyright(2010); ?> Company Name

There ya go!

Isn’t making your life easier fun!? I sure think so!

Speeding Up MySQL with Indexes

John Hass — Fri, 18 Dec 2009 14:30:05 +0000

MySQL is an excellent database product and even though Oracle just bought out Sun, who bought out MySQL, Oracle still promised to keep up with MySQL patches and releases. (see more here) This is great news for all us die hard MySQL and PHP guys, we no longer have to worry about giving up our MySQL for something else (because you can have my PHP when you pry it from my cold dead fingers). Though the question of the day is, when we get Millions of records how can we speed it up. Say for example I have a callrecord database that has a few things in it

id|start_time|from_number|to_number|billsec

When I do a query by id everything is fast, but when I do a query by from_number everything is really slow, maybe even taking hours to complete. So lets create an index on the from_number to make it faster.

CREATE INDEX full_from_number ON table_name (from_number);

Now depending on the number of records you have this could take sometime. You can check on the status by opening another MySQL session and typing “show processlist”. This will show you what is currently going on in MySQL. It may appear that your MySQL has froze, but it hasn’t. Be patient, I had a database take 18 hours before.

Why not index all fields? This is a good question, but it is important to only index the fields that you perform a where on, creating an index, does slow the insert time some, but in my example with the callrecord database, I only filled it once a day and queried 100 times the next day, so creating extra indexes was a good thing to do.

Send An HTML & Plain Text Email Using An SMTP Server With PHP & PEAR

Tony Virelli — Wed, 15 Apr 2009 09:31:51 +0000

You have to have PEAR installed. You can get more information at http://pear.php.net.


include('Mail.php');
include('Mail/mime.php');
 
$text = 'Hello,\nHow are you doing?';
$html = 'Hello,
How are you doing?';
 
$smtpinfo["host"] = "smtp.domain.com";
$smtpinfo["port"] = "25";
$smtpinfo["auth"] = true;
$smtpinfo["username"] = "SMTP USERNAME";
$smtpinfo["password"] = "SMTP PASSWORD";
 
$recipients = "recipient@domain.com";
$headers["From"] = "From Name ";
$headers["To"] = "recipient@domain.com";
$headers["Subject"] = "Email Subject";
 
$mime = new Mail_mime();
$mime->setTXTBody($text);
$mime->setHTMLBody($html);
 
$body = $mime->get();
$headers = $mime->headers($headers);
 
$mail =& Mail::factory('smtp', $smtpinfo);
$mail->send($recipients, $headers, $body);
 
if(PEAR::isError($mail)){
echo("
 
There was an error: " . $mail->getMessage() . "
 
");
}else {
echo("
 
Message Sent To $to
 
");
}
?>

Simple PHP HTTP Authentication Page Protection

Tony Virelli — Wed, 29 Oct 2008 09:58:41 +0000

If you want to secure a web page, but don’t want to have integrate a database and don’t require unique usernames and passwords for each user this solution may work for you!


function passwordProtect($username, $password){
if (
(
!isset($_SERVER['PHP_AUTH_USER']) ||
(
isset($_SERVER['PHP_AUTH_USER']) &&
$_SERVER['PHP_AUTH_USER'] != $username
)
) &&
(
!isset($_SERVER['PHP_AUTH_PW']) ||
(
isset($_SERVER['PHP_AUTH_PW']) &&
$_SERVER['PHP_AUTH_PW'] != $password
)
)
)
{
header('WWW-Authenticate: Basic realm="Login"');
header('http/1.0 401 Unauthorized');
echo 'Please Login to continue.';
exit;
}
}
?>

Then to use the code simply echo the function

 echo passwordProtect('username', 'password'); ?>
