What Is PHP?

PHP is a power that has outgrown its name. It was originally planned as a ordered of macros to support coders reassert individualized bag pages, and its study grew from its purpose. Since then, PHP’s capabilities hit been extended, attractive it beyond a ordered of utilities to a full-featured planning language, confident of managing Brobdingnagian database-driven online environments.

As PHP’s capabilities hit grown, so likewise has its popularity. According to NetCraft (http://www.netcraft.com), PHP was streaming on more than 1 meg hosts in Nov 1999. As of Sept 2001, that amount had already risen to over 6 meg hosts, and by Oct 2003 PHP was reportedly installed on nearly 14 meg hosts. According to SecuritySpace.com, PHP is the most favourite Athapascan power available, fighting mod_ssl, Perl, and FrontPage.

PHP is officially famous as PHP: Hypertext Preprocessor. It is a server-side scripting power ofttimes cursive in an HTML context. Unlike an mediocre HTML page, a PHP playscript is not dispatched direct to a computer by the server; instead, it is parsed by the PHP engine. HTML elements in the playscript are mitt alone, but PHP cipher is understood and executed. PHP cipher in a playscript crapper ask databases, create images, feature and indite files, speech to far servers—the possibilities are endless. The production from PHP cipher is compounded with the HTML in the playscript and the termination dispatched to the user.

PHP is also installed as a command-line application, making it an superior agency for scripting on a server. Many grouping administrators today ingest PHP for the variety of mechanisation that has been traditionally handled by Perl or bomb scripting.

Sometimes you requirement to create unequalled randon drawing if you poverty to distribute IDs to your members or distribute unequalled values to your shopping cart items. Here I’m meet citing to think whereas it depends on you for what determine you’d same to create a haphazard sort in your PHP scripts. I hit cursive a diminutive duty that takes digit argument. This discussion tells the duty how some digits you poverty in the generated number.

For a springy warning of the article, go to
http://www.aboutwebdesigning.com/2005/09/29/generate-a-random-number-using-php

First, here’s the function:

function random_num($n=5)
{

return rand(0, pow(10, $n));
}

If you beam no discussion to the random_num() function, it generates a 5-digit haphazard number. This is how we ingest it:

echo random_num(); gave 96161 when proven and
reflexion random_num(7); gave 5983582 when tested

This duty uses the PHP science duty pow() to intend the sort of digits we want. The duty pow() calculates the noesis of a sort same feature 10 upraised to the noesis 5. In science we indite it same 10 Exp 5. Basically, the actual rand() duty takes 2 arguments: the modify bounds and the bunk limit. So if you poverty to create a haphazard sort that should be greater than 107 and inferior than 5067, you strength intend somethin like:

echo rand(107, 5067); gave 3456 when tested

Since we ordinarily don’t requirement the bunk limits and the modify limits, I’ve elucidated a generic duty that gives you a haphazard sort of spedicif sort of digits.

วิธีทำ SEO

When a individual signs up at your website, you haw poverty to avow their telecommunicate come so you aren’t effort phoney accounts in your database. A some lines of cipher crapper beam an telecommunicate to the come specified, containing a recognize acknowledgement and unification to alter their account. PHP is the prizewinning artefact to both beam the emails and do the activation process.

When the unification in the telecommunicate is clicked, a PHP tender is unexploded that performs a pair ultimate determination techniques, and if valid, it activates the account. PHP checks for the telecommunicate come in the database and makes trusty the haphazard uncertain bespoken to the address is the digit generated at statement creation to be utilised for activation. If these conditions are met, the statement is activated.

Some sites also earmark the individual to resend the activation email, which makes the statement activation cipher a lowercase longer. PHP then has to withdraw the continuance for the older activation uncertain and append a newborn arbitrarily generated uncertain in the database. The playscript also has to beam the telecommunicate again, but with a assorted messaged bespoken – same “This is a resent commendation telecommunicate to alter your statement with us”.

A PHP Redirect automatically transfers a scheme individual from digit address to another. For example, typewriting foo.com in the application automatically transfers the individual to added address bar.com.

The PHP Redirect command:

Replace [some-url] with the address where you poverty the redirection to verify place.

For example,

header(“location: ./version2/index.html”);
=>redirect to “index.html” tender in subfolder titled “version2″

header(“location: http://www.yahoo.com”);
=>redirect to a website titled yahoo.com

If PHP is not available, it’s also doable to ingest another redirects:

* protocol Redirects

Replace [time] with seconds. This module disrupt the application for the given sort of seconds. Replace [some-url] with the direct address you poverty to redirect.

For example,

The above protocol supported direct needs to be in the location of the HTML code.

* JavaScript Redirects

setTimeout(“location.href=’[some-url]‘”, [time]);

Replace [time] with milliseconds. This module disrupt the application for the given sort of seconds. Replace [some-url] with the direct address you poverty to redirect.

For example,
setTimeout(“location.href=’http://www.yahoo.com’”, 5000);

The above JavaScript supported direct crapper be either in the or location of the HTML code.

Usually a PHP direct is such more sure than another add of redirects same protocol direct or JavaScript supported redirects. For warning a JavaScript direct haw not impact if a user’s application settings has JavaScript overturned off.

The think ground PHP redirects module impact no concern what settings users hit on their application is because PHP is computer lateral script. It module not depend on application settings that haw change JavaScript which is parsed on the client-side/user-side.

Dynamic database-driven sites have become very popular, and relatively easy to set up and administer, through the use of Content Management Systems (CMS) and PHP server-side scripting. It’s also possible to create a fancy-looking site with little actual content, or automatically generated code that can harm your SEO, such as multiple URLs that display identical content.

Search engines are constantly evolving and adapting in response to changes in the way information is presented on the web. Strategies that were once necessary to ensure inclusion of PHP pages are no longer required.

It was once helpful to generate a static HTML version of a PHP page so that all the “includes” could be indexed. Now search spiders “see” all the content on a PHP page, the same way it is viewed in a browser.

It used to be prudent to avoid dynamic URLs containing “? & =” – now, the search engines list URLs with the dynamic variables. However, it is best to compose them with no more than three variables. Some variable-laden URLs may be listed, but without any accompanying content/description, in the search results… Stay tuned for further developments as the search engines refine their methods.

——

With many hosts running the popular Apache server, developers are expanding the use of PHP by modifying the .htaccess file to allow PHP code processing within HTML documents, and enabling shorter URLs with fewer variables by configuring httpd.conf. Your web hosting provider’s support team should be able to tell you if these features are available for your site.

Implementing a common-sense approach to SEO for your PHP site requires cooperation and coordination among the developer, webmaster, and web host. Beware of “SEO Experts” with “secret methods” and “guaranteed results” – gimmicks that kludge the search spider today might hurt your ranking tomorrow.

A descriptive and catchy page title is one of the key elements of SEO – whether or not your site uses PHP – since it becomes the linked title of your search engine listing. Use the name of your site in the title to encourage branding, along with a brief capsule about the specific page. Remember that the title displays at the top of the browser window and in the menu bar, so keep it brief, less than 160 characters. Avoid using identical titles on multiple pages (this can easily happen with dynamically generated titles) because they may not be listed individually, and if they are listed separately, it’s confusing. Meta tags for description and keywords have become less crucial to SEO – but that doesn’t mean you should forget about them.

The basic principles of SEO that apply to static HTML sites also apply to dynamic PHP sites:

● Provide engaging and valuable content presented in an attractive design.

● Code should be error-free and standards-compliant.

● Use keywords appropriate to your subject matter – don’t be tempted to use “tricks” that might end up hurting your search engine listing.

● Encourage repeat visits with frequent updates, interactive features, membership sign-up, opt-in newsletters and, if appropriate, “freebies” – contests, giveaways, downloads and other resources.

● Encourage linking to your site with copy & paste code. Reciprocal links build partnerships and enhance page rank, but avoid hosting bulky “link farms” and other venues for worthless web site spam.

● Make use of tools provided by the search engines, such as creating a sitemap.

● Educate yourself by reading the search engine faqs, as well as by perusing some independent forums for SEO tips and methods.
