Php Mysql InnoDB ve MyISAM farkları

Burhan KARADERE — Wed, 18 Jan 2012 06:44:36 +0000

InnoDB ve MyISAM

Olaya MyISAM yönüyle bakarsak;

MyISAM daha ziyade okuma (select) yapılan tablolarda tercih edilir çünkü InnoDB gibi farklı tablolarla ilişki kurmadığından daha hızlı şekilde okuma yapılabilir.
MyISAM full text search özelliğine sahiptir.
Transaction desteği yoktur; bu nedenle hızlı çalışsa bile yaptığınız işlemleri geri alamazsınız; veri bütünlüğü yoktur.
Bir kayıt eklenirken veya update edilirken tüm tabloyu kilitlediği için fazla insert-update edilecek tablolarda performansı düşüktür.
Farklı kaynaklarda farklı rakamlar verilse de sakladığınız veri yaklaşık 2GB’ı geçtiği zaman performansı gözle görülür şekilde düşer.
Foreign key desteği yoktur.
Tasarlanması kolaydır.

InnoDB yönüyle bakarsak;

Transaction desteği vardır, veri bütünlüğü yönüyle MyISAM’dan çok daha avantajlıdır.
Foreign Key desteği vardır.
Veri tabanı tasarımı daha zordur.
Full text search özelliği yoktur.
Insert ve Update işlemlerinde sadece kayıt yapılan satırı kilitleyip tüm tabloyu kilitlemediği için daha performanslıdır.
MyISAM’a göre daha fazla sistem kaynağına ihtiyaç duyar.

Frontpage 2003 ile Php kullanımı. Using PHP with FrontPage 2003

Burhan KARADERE — Thu, 10 Nov 2011 07:42:45 +0000

Merhaba arkadaşlar hala frontpage kullanyorsanız benim gibi vazgeçemiyorsanız 2003 frontpage ile php yazmanın yolu aşağıdaki gibidir.

koay gelsin .

Microsoft kaynak / source : http://office.microsoft.com/en-au/frontpage-help/using-php-with-frontpage-2003-HA001109299.aspx

This article was adapted from Microsoft Office FrontPage 2003 Inside Out by Jim Buyens. Visit Microsoft Learning to learn more about this book.

You can use PHP to build sophisticated and complex Web applications and external and internal business channels, such as e-commerce sites, corporate portals, and intranets. Microsoft offers an alternative to scripting with PHP — ASP.NET — which is described in more detail later in this article. As might be expected, FrontPage supports the Active Server Pages (ASP) and ASP.NET technologies more completely than it does PHP. However, if you reconfigure certain settings, FrontPage and PHP can work together.

What is PHP?

PHP is a server-side scripting language (scripting language: A simple programming language designed to perform special or limited tasks, sometimes associated with a particular application or function.) that you can embed into HTML when you create dynamic Web pages. PHP is an open-source product that you can use, alter, and redistribute without charge. Originally PHP stood for Personal Home Page tool, but over time it has evolved to stand for PHP: Hypertext Preprocessor.

In general, dynamic Web pages are pages that interact with users, so that each site visitor sees customized information. In the case of PHP, dynamic also means that data is pulled from a database. Dynamic Web applications are prevalent in commercial (e-commerce) sites, where the content displayed is generated from information that is accessed from a database or other external source.

PHP’s syntax is similar to that of C and Perl, making it easy to learn for anyone with basic programming skills. PHP supports only partial encapsulation (such as support for declaring methods and fields in the class) and partial polymorphism (no overloading, no abstraction). With PHP, there is no concept of private, public, or protected functions in classes as well as in the overloading.

Create pages that contain PHP scripts

When you use PHP with FrontPage 2003, you create the overall Web page design and insert any fixed elements by using Design view in FrontPage. You can then write the HTML code that contains the variable portion of each PHP response in Code view. Of course, when you are laying out the Web page design, you may want to create placeholders to indicate where the variable output should appear, so that you can easily locate where you want to add the PHP script.

PHP scripts must reside in an executable directory. For reasons of security and resource consumption, many server administrators tightly control access to such directories. If you do not administer your own Web server, you need permission from the server administrator to run server-side scripts.

Change settings in FrontPage 2003

Before you can use PHP with FrontPage 2003, you must make the following changes to settings in FrontPage:

Disable features that require the FrontPage Server Extensions

If the Web server that runs your PHP pages has the FrontPage Server Extensions from Microsoft installed, do the following:

On the Tools menu, click Page Options, and then click the Authoring tab.
Under FrontPage and SharePoint technologies, clear the SharePoint Services and Browse-time Web Components check boxes.

Disable features that create ASP or ASP.NET code

If the Web server that runs your PHP pages can also run ASP, do the following:

On the Tools menu, click Page Options, and then click the Authoring tab.
Under Browsers, clear the Active Server Pages check box.

Enable and use ASP-style <% %> code delimiters

Do the following:

Open the php.ini (php.ini: The master configuration file for PHP that you can customize to help you control the way PHP works on your site.) file on the Web server, and set asp_tags="1".
Use ASP-like <% and %> tags instead of the tags. This stops FrontPage from reformatting your PHP code.

Note As an alternative, you can use tags instead of tags.

Configure PHP file extensions to open in Design view

On the Tools menu, click Options, and then click the Configure Editors tab.
In the Extensions list, locate and select the file extension that you want to use.
In the Editors list, select FrontPage (Open as HTML).
Click Make Default.

If the extension that you want does not appear, you must add it.

How?

Click the New Extension button (or press ALT+N), located above the Extensions list.
In the Open With dialog box, type the file extension that you want in the Extension box.
Select FrontPage (Open as HTML), and then click OK.

ASP.NET — an alternative to PHP

If you are using PHP with FrontPage and find that it prevents you from accomplishing what you want in your Web site, you might consider using ASP.NET instead.

ASP.NET is part of the Microsoft .NET Framework, which is a feature of Microsoft Windows®. Unlike PHP, ASP.NET is not a language or a parser but rather a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.

Microsoft ASP.NET pages run on the server like PHP and generate markup, such as HTML, WML, or XML, which is sent to a desktop or to mobile applications. ASP.NET provides a robust, object-oriented, event-driven programming model for developing Web pages, while still maintaining the simplicity that PHP developers are accustomed to.

ASP.NET applications are based on a robust Object Oriented Programming (OOP) paradigm rather than a scripting paradigm. This allows for more advanced OOP features, such as inheritance, encapsulation, and reflection.

If you are considering migrating to ASP.NET, in most cases it is not very complex for simple to small applications. Due to underlying architectural differences as well as the ASP.NET OOP paradigm, more sophisticated and complex applications must be well planned to take advantage of the more rigorous separation of display from logic and data in ASP.NET, as well as its time-saving, built-in functionality that significantly reduces the amount of code necessary to perform comparable tasks.

Php tr tükçe karakter sorunu, array de tr karakter sorunu giderme, replace to charset

Burhan KARADERE — Mon, 26 Sep 2011 10:53:21 +0000

Merhaba arkadaşlar klasik php de tr sorunu çıldırtır insanı, bunun sebebi standar charset table dünyada oluşturulurken bizim çok bilmiş mühendislerin veya devletimizin ilgili kurumunun bu standartın oluşturulma sırasındaki toplantılara gitmemesi önemsemesi bizim yıllarca bu sorunu yaşamamıza , sebep olması buda biz türklerin çilesi

sorunu normalde

head ekleyip deneyin olmadı bunu deneyin

olmadı php sayfasının en başına bunu sadece birkere kullanın include lar var ise

olmadı db connectondan sonra alttaki donusturuculeri deneyin.

$db_con = mysql_connect($dbhost, $dbuser, $dbpass) or die (‘Error connecting to mysql’);

mb_internal_encoding(‘UTF-8′);
mysql_query(‘SET NAMES UTF8′);
mysql_query(“SET CHARACTER SET utf8″);

// mysql_query(“SET COLLATION_CONNECTION = ‘utf8_turkish_ci’”);
mysql_query(“SET COLLATION_CONNECTION = ‘utf8_general_ci’”);

hala olmadı ise en ilkel yöntem strin değiştirme ile karakter değiştireceğiz.

$gelendata = “Ey türk Gençliği”;
$trharfler = array(‘Ç’, ‘ç’, ‘Ğ’, ‘ğ’, ‘ı’, ‘İ’, ‘Ö’, ‘ö’, ‘Ş’, ‘ş’, ‘Ü’, ‘ü’);

$trkodharfler = array(‘& Ccedil;’, ‘& ccedil;’, ‘& #286;’, ‘& #287;’, ‘& #305;’, ‘& #304;’, ‘& Ouml;’, ‘& ouml;’, ‘& #350;’, ‘& #351;’, ‘& Uuml;’, ‘& uuml;’);

$degismishali = str_replace($trharfler, $trkodharfler, $gelendata);

Not : blogda gosterebilmek için & sonra boşluk koydum kodun çalışması için & ‘den sonraki boşlukları simeniz gerekecek.

bunu function halne getirelim:

function TrDuzelt($gelendata ){

$trharfler = array(‘Ç’, ‘ç’, ‘Ğ’, ‘ğ’, ‘ı’, ‘İ’, ‘Ö’, ‘ö’, ‘Ş’, ‘ş’, ‘Ü’, ‘ü’);

$degismishali = str_replace($trharfler, $trkodharfler, $gelendata);

return $degismishali ;

}

Ajaxçılar için
// ajax problemlerinde
function AjaxTrDuzelt($newphrase) {
$newphrase = str_replace(“Ãœ”,”Ü”,$newphrase);
$newphrase = str_replace(“Åž”,”Ş”,$newphrase);
$newphrase = str_replace(“Äž”,”Ğ”,$newphrase);
$newphrase = str_replace(“Ã‡”,”Ç”,$newphrase);
$newphrase = str_replace(“Ä°”,”İ”,$newphrase);
$newphrase = str_replace(“Ã–”,”Ö”,$newphrase);
$newphrase = str_replace(“Ã¼”,”ü”,$newphrase);
$newphrase = str_replace(“ÅŸ”,”ş”,$newphrase);
$newphrase = str_replace(“Ã§”,”ç”,$newphrase);
$newphrase = str_replace(“Ä±”,”ı”,$newphrase);
$newphrase = str_replace(“Ã¶”,”ö”,$newphrase);
$newphrase = str_replace(“ÄŸ”,”ğ”,$newphrase);

return $newphrase;
