]]> - System Requirements Check option should be used to ensure proper system behavior in the current environment.]]> + The System Requirements Check option should be used to ensure proper system behavior in the current environment.

+

+ PHP version 5.2.0 or above*
+ Use this PHP version or better to ensure normal website operation on every day basis. +

+

+ URL rewriting support
+ Allows to build nice looking SEO urls without specifying "/index.php" in each of them. +

+

+ Java template compression
+ When Java is installed on web server, then it's possible to use YUI Compressor + to minify HTML, CSS and JavaScript output of website. This allows to make websites, which opens even faster, then before. +

+

+ Memory caching support
+ When available use Memcached memory object caching system for data caching. + Will severely improve website performance under heavy load and page loading speed in general. +

+

+ Accessing remote resources (via cURL)
+ Allows to perform data retrieval from other websites (e.g. rss feeds) in background. Data retrieval internally is done + using cURL library, that must be installed on web server. +

+

+ XML document processing (via SimpleXML)*
+ In-Portal uses XML files to store module/theme meta data. This + library is used keep In-Portal + code clean as fast even, when processing XML files. +

+

+ Standard PHP Library (SPL)*
+ Usage of this library guarantees memory + efficient way to manage files and data structures across In-Portal. +

+

+ TrueType font support (via Freetype)*
+ This library allows to use TrueType fonts inside produced images. In particular it's used for Captcha code generation. +

+

+ GD Graphics Library 1.8 or above*
+ This library is used to perform various manipulations (e.g. resize, crop, etc.) + on user-uploaded images. +

+

+ JPEG images support*
+ Support image manipulations on user-uploaded images *.jpg and *.jpeg file extensions. +

+

+ Database connectivity (via MySQL)*
+ In-Portal uses MySQL database as it's persistent data storage. +

+

+ JSON processing support*
+ JSON data format is used to implement AJAX + approach and perform complete page reload only, when necessary. +

+

+ Memory requirements changing on the fly
+ In-Portal requires at least 16 megabytes of memory to operate normally. However some resource consuming + operations (like link validation) might consume more memory, then usual. To ensure, that such operations + never fail In-Portal changes maximally allowed memory limit on the fly. See + memory_limit setting + for more info. +

+

+ Prevent script errors in production environment
+ Prevents any errors to be shown on website, that might happen due incorrect web server configuration. See + display_errors setting + for more info. +

+

+ Change error detalization level
+ Ensures, that all error types are shown in development environment and none in production environment. See + error_reporting setting + for more info. +

+

+ Web server timezone is explicitly set*
+ Web server timezone must be set explicitly to ensure correct date/time calculations and display across the website. + See date.timezone + setting for more info. +

+

+ Needed super-global arrays registered
+ Internally In-Portal relies on super-global array (e.g. $_SERVER, $_POST, etc.) presense inside a script. To make that happen + variables_order setting must contain + following letters: "G", "P", "C", "S". +

+

+ Script output buffering enabled*
+ Output buffering is needed to allow usage of GZIP compression of page output. See + output_buffering + setting for more info. +

+

+ Cookies enabled
+ However In-Portal can work without cookies (by adding ?sid=XXXXXXXX into each page url), but it's strongly + advised to use cookies-enabled web browser for better user expirience. +

+

+ JavaScript enabled
+ JavaScript might not be required on Front-End (depends on used theme), but it must be enabled in web browser + during installation and Admin Console usage. +
