Hi Jeyaseelan
You can use the following function for string image

$vFontName //#-- You can give font name like FRSTGRDR.TTF but this font available in Your server.... then only you can write a text,no need to install this font just put a font in separate folder and give a path this is enough..

Thanks

Hi,

Installation of mcrypt extensions on Windows

After installing PHP and a web server on Windows, you will probably want to install some extensions for added functionality. You can choose which extensions you would like to load when PHP starts by modifying your php.ini. You can also load a module dynamically in your script using dl().

The DLLs for PHP extensions are prefixed with php_.

Many extensions are built into the Windows version of PHP. This means additional DLL files, and the extension directive, are not used to load these extensions. The Windows PHP Extensions table lists extensions that require, or used to require, additional PHP DLL files. Here's a list of built in extensions:

In PHP 4 (updated PHP 4.3.11): BCMath, Caledar, COM, Ctype, FTP, MySQL, ODBC, Overload, PCRE, Session, Tokenizer, WDDX, XML and Zlib

In PHP 5 (updated PHP 5.0.4), the following changes exist. Built in: DOM, LibXML, Iconv, SimpleXML, SPL and SQLite. And the following are no longer built in: MySQL and Overload.

To Download mycrypt from http://files.edin.dk/php/win32/mcrypt/libmcrypt.dll and copy to C:\php\extensions\php_mcrypt.dll

The default location PHP searches for extensions is C:\php4\extensions in PHP 4 and C:\php5 in PHP 5. To change this setting to reflect your setup of PHP edit your php.ini file:

You will need to change the extension_dir setting to point to the directory where your extensions lives, or where you have placed your php_*.dll files. For example:

extension_dir = C:\php\extensions

Enable the extension(s) in php.ini you want to use by uncommenting the extension=php_*.dll lines in php.ini. This is done by deleting the leading ; from the extension you want to load.

// change the following line from ...
;extension=php_mcrypt.dll

// ... to
extension=php_mcrypt.dll

After that check the phpinfo.php

Regards,
sivaraman.

Hi Siva,
I hope that you have provided enough information to know the better captcha installation for windows server for PHP.

Thank you
