Die betowering van WordPress

December 9th, 2010

One of the premier web hosting sites is WordPress. WordPress is a company that is dedicated to helping their customers set up professional websites quickly and easily. There are numerous advantages to using WordPress as your web hosting platform. It offers a huge variety of template design options that enable a layperson to construct a professional website in just a few hours. Another benefit is that WordPress is search engine optimized, which means that your website will be prominently displayed in the search engine results. Daarbenewens, WordPress allows you to quickly update your visitors through an RSS feed option.

Since WordPress is relatively easy to use and is very popular, there are thousands of plug-ins that allow you to customize your website design. WordPress is truly magical in allowing people who don’t know programming to design a great website. For example, if there is a specific function that you want your website to carry out, you can download the appropriate plug-in and activate it on your website by going to your WordPress account administration tab. With so many options available to WordPress users, the ability to creatively design a unique website is unparalleled.

For the best web hosting, WordPress is the gold standard. Because of the SEO that is already incorporated into the WordPress platform, the customer’s search engine ranking will be higher than it would be with many other website hosting sites. In order to keep your search engine results at a high ranking level, it is important to frequently update your website with original content. Daarbenewens, when you post a sale or special event on your website, it will be found by the search engines more rapidly and your ranking will increase, so that you are closer to the top of the search engine results. This in turn will generate more traffic to your site and broaden your prospective customer base.

Another great aspect of WordPress is that it has a built-in RSS feed. An RSS feed is an efficient way for your visitors to be regularly updated about your activities. When new content has been added to your site or you have posted a new blog entry, the visitors who subscribe to your RSS feed are immediately notified via e-mail by WordPress. This function will save you a lot of time because the program does the work of updating your visitors for you.

Among the numerous web hosting sites, there are many advantages to using WordPress to design and host your website. The program is very user-friendly and quite customizable to fit your market niche. Daarbenewens, WordPress is already search engine optimized, so you will benefit from being highly-ranked in the search engine results. If you want to take a look at some websites that are designed with WordPress, here are a few excellent examples: The Department of Environmental Science at the University of Virginia, Ford Motor Company and Outreach Magazine.

If you are engaged in an online marketing campaign, consider utilizing the magic of WordPress. The platform will enable you to construct a great website with ease. With a professional website that you can update easily, you will be able to stay ahead of the competition and increase your market share

PHP Error Nesting Level Too Deep Recursive Dependency

March 12th, 2010

I’ve installed PHP 5.2 at one of my testing computers today and a couple of bits of code that previously worked fine in version 5.1.6 threw fatal errors in the new version. The error message was “Nesting level too deep – recursive dependency?” and it took a little time

to track down the root of the problem. Here’s what I’d done wrong.

In PHP there are two comparison operators, == and ===. It’s generally known that the first is not strict about type but the second is. So, for example

echo ( false == 0 ); // true

echo ( false === 0 ); // false

– 0 is an integer and false is a boolean

My problem arose from using non-strict typing with objects.

$a = new MyObj();
$b = new MyObj();
if( $a == $b )
…

I hadn’t considered what I was doing with this code. When comparing two objects using the non-strict comparison operator (==) PHP compares all the properties of the objects and if they match the objects are deemed to be equal. If they don’t match they are not equal. In effect, we have a recursive comparison of all the properties of each object, and all their properties, ens. until we reach basic data types like strings and integers.

If, egter, we use strict comparison (===), PHP will check whether the two objects are exactly the same object, not just objects with the same properties.

class MyObj
{
public $p;
}

$a = new MyObj();
$b = new MyObj();
$c = new MyObj();
$a->p = 1;
$b->p = 1;
$c->p = 2;
echo ( $a == $c ); // false
echo ( $a == $b ); // true
echo ( $a === $b ); // false

The problem arises if you have circular references in your objects properties. So, for example

class MyObj
{
public $p;
}
class OtherObj
{
public $q;
}

$a = new MyObj();
$b = new OtherObj();
$a->p = $b;
$b->q = $a; // the circular reference: $a->p->q === $a

$c = new MyObj();
$d = new OtherObj();
$c->p = $d;
$d->q = $c;// another circular reference: $c->p->q === $c

echo ( $a == $c ); // Fatal error:
Nesting level too deep – recursive dependency?

In order to compare $a to $c, PHP must compare their properties. So the logic in PHP goes something like this: $a == $c if $a->p == $c->p if $a->p->q == $c->p->q if $a->p->q->p == $c->p->q->p etc. indefinitely.

PHP 5.1 seemed to smooth over the problem somehow (probably after a certain level of recursion it simply returned false) – and usually it worked out fine. PHP 5.2 correctly produces the fatal error above.

Once you know the problem, the solution is easy – use strict comparison.

echo ( $a === $c ); // false (and no error)

The strict comparison will simply check whether the two objects are at the same location in memory and so doesn’t even look at the values of the properties.

N.B. The same problem can arise when using the negated comparison operators (use !== instead of !=) and when using in_array (use in_array’s third parameter to indicate strict comparison).

How to receive and parse emails using POP3 and PHP

March 1st, 2010

I would like to describe some methods on how to write the processor for incoming mail. I had to use such manipulation to parse e-mails received from various sources. This can be useful for writing your own spam filter system, answering machine or ticket system to receive applications by e-mail.

To implement the e-mail parser algorithm we need

connect and log-on to e-mail server
count the number of incoming letters
recive e-mail from the server using POP3 protocol
process the e-mail headers and body and make parsing
… implement any additional actions

Ok, there is very specific task for PHP coding, so we need hosting that supports external connection. I do not propose to write decision entirely because much has been realized by talented programmers already. For example, you can take a ready module which will allow accept e-mails from a remote server.

Thank’s to Manuel Lemos and his module (php class) which named pop3.php.

To connect that class to your code, you just need to use include or require command: require(“pop3.php”);


hostname=$hostname;
$result=$pop3_connection->Open();
 
// We are trying to open connection and display the result
echo $result;
// Trying to logon and display the error if any appear
$error=$pop3_connection->Login($user,$accesscode,$apop);
if ($error<>'Password error: Logon failure: unknown user name or bad password.') {echo $error; exit;}
// Now get the statistic how many emails are stored and the size of them $result=$pop3_connection->Statistics($messages, $size);
echo "$hostname contains  $messages of $size bytes.";
 
//..... There we can receive e-mails in the cycle and parse them.... //
 
// If nothing to do - we can close the connection
$error=$pop3_connection->Close(); //
echo $error;
?>

Now we know how to connect and log-on to the POP3 server and how to request the number of Inbox e-mails and them sizes. Next, we should receive each e-mail and parse the headers and body array.

Gratis MBOX te EML Converter

Dit is goed dat daar vandag nog programmeerders wat skryf uitstekende sagteware teen geen koste. Wat ek praat? Wil jou vertel hoe ek het nog 'n program vir my versameling moet-hê utilities. Apple MAC computers are widespread used in our office. Dit is die beleid van die maatskappy. Despite the policy

Apple MAC rekenaars is wydverspreid in ons kantoor. Dit is die beleid van die maatskappy. Ten spyte van die beleid van die maatskappy, ons baas verkies Windows en gebruik sy featured laptop. Wie moet die reëls te breek? Natuurlik die baas, the rest is not allowed 🙂 I must say that I share that preference, so ek het Windows geïnstalleer 7 na my huis laptop.

Ons prokureurs moet sommige ondersoeke van tyd tot tyd te slaag en hulle moet die korrespondensie van ons personeel hersien, maar hulle aanvaar slegs die lêers in die Outlook PST formaat.

In 'n vorige artikel Ek het geskryf oor ongelooflik nodige program Wizard Outlook Import, wat vir my 'n klomp van die tyd wanneer gered invoer EML lêers in Outlook. Die taak wat ek moes voltooi net sit my in skok. Dit is nodig om e-posse van ons werknemers te omskep in die Outlook .Pst lêer. Hoe kan ons onversoenbare dinge te versoen? Hoe om MAC OS kombineer met die Windows?

For a start I had to conduct an audit and found that our employees using various e-mail clients. There are just some of them: Turnpike, Mac Mail, Entourage, MailCopa, Thunderbird, Eudora, Berkeley Mail. The conversion task did not seem doable. Ek het besluit dat as 'n soektog nie onmiddellik bring my die oplossing, dan sal ek sê vir my baas dat die missie is onmoontlik. So ek het op soek na die frase “gevolg, Thunderbird, Mac pos, om EML gratis mbox PST” en die soektog was suksesvol, dit bewys iets wat ek nooit verwag. Verder, die woord VRY nie ooreenstem met my met die taak wat te doen gehad het. Stel jou my verbasing toe op die beskrywing bladsy van die ander een EML te PST converter, Ek het gevind dat die gratis mbox te EML converter.

Die sagteware review getoon dat ten spyte van die feit dat die program is gratis, dit het die ongelooflike potensiaal. Maar die posbus lêers formaat van verskillende programme wissel, the program was able accurately identify all meta signatures and correctly recognize the file format. I’m not kidding, all mailbox files Turnpike, Mac Mail, Entourage, MailCopa, Thunderbird, Eudora en Berkeley Mail were transformed into arrays of e-mail files in EML format. Having the Wizard Outlook Import at my hands allow me to import all eml files into Outlook PST.

Gratis MBOX te EML Converter works as a batch-processor. First you should select all necessary mbox files from which you want to retrieve eml messages. It is easy to select all files with the Shift key. After that, you need click the Processing button, point to the empty directory at your hard drive and wait for the result. The program processing all files sequentially, it creates a directory for each file and fill it with extracted eml files. In my geval het ek 'n baie posbus lêers wat in ooreenstemming met die gebruiker-name van ons mense is vernoem. Uiteindelik het ek het 'n baie dopgehou, elkeen het 'n gebruiker naam en vervat al ooreenstemmende EML lêers opgespoor van die posbus.
