About

PHP is a scripting language designed to fill the gap between SSI (Server Side Includes) and Perl, intended for the Web environment. Its principal application is the implementation of Web pages having dynamic content. PHP has gained quite a following in recent times, and it is one of the frontrunners in the Open Source software movement. Its popularity derives from its C-like syntax, and its simplicity. The newest version of PHP is 7.0 and it is heavily recommended to always use the newest version for better security, performance and of course features.

If you've been to a website that prompts you to login, you've probably encountered a server-side scripting language. Due to its market saturation, this means you've probably come across PHP. PHP is even used to run sites such as Wikibooks. PHP was designed by Rasmus Lerdorf to display his resume online and to collect data from his visitors.

Basically, PHP allows a static webpage to become dynamic. “PHP" is an acronym that stands for "PHP: Hypertext Preprocessor". The word "Preprocessor" means that PHP makes changes before the HTML page is created. This enables developers to create powerful applications that can publish a blog, remotely control hardware, or run a powerful website such as Facebook or Wikipedia. Of course, to accomplish something such as this, you need a database application such as MySQL.

About

The PHP Data Objects extension is currently included by default with installations of PHP 5.1. It is available for users of PHP 5.0 through PECL, but does not ship with the base package.

PDO uses features of PHP that were originally introduced in PHP 5.0. It is therefore not available for users of PHP 4.x and below.

PHP Data Objects has a number of significant differences to the MySQL interface used by most PHP applications on PHP 4.x and below:

• Object-orientation. While the MySQL extension used a number of function calls that operated on a connection handle and result handles, the PDO extension has an object-oriented interface.

• Database independence. The PDO extension, unlike the MySQL extension, is designed to be compatible with multiple databases with little effort on the part of the user, provided standard SQL is used in all queries.

• Connections to the database are made with a Data Source Name, or DSN. A DSN is a string that contains all the information necessary to connect to a database, such as 'MySQL:dbname=test_dB'.

About

A cache is a collection of duplicate data, where the original data is expensive to fetch or compute (usually in terms of access time) relative to the cache. In PHP, caching is used to minimize page generation time. PHP basically has two main types of caching: 'output caching' and 'parser caching'. PHP 'output caching' saves a chunk of data somewhere that can later be read by another script faster than it can generate it. 'Parser caching' is specific feature. PHP is a scripting language and code is not compiled or optimized to a particular computer. Every PHP file must be parsed and that takes time. This type of time minimization is 'parser caching'.

About

Sessions allow the PHP script to store data on the web server that can be later used, even between requests to different PHP pages. Every session has a different identifier, which is sent to the client's browser as a cookie or as a $_GET variable. Sessions end when the user closes the browser, or when the web server deletes the session information, or when the programmer explicitly destroys the session. In PHP, it's usually called PHPSESSID. Sessions are very useful to protect the data that the user wouldn't be able to read or write, especially when the PHP developer doesn't want to give out information in the cookies as they are easily readable. Sessions can be controlled by the $_SESSION superglobal. Data stored in this array is persistent throughout the session. It is a simple array. Sessions are much easier to use than cookies, which helps PHP developers a lot. Mostly, sessions are used for user logins, shopping carts and other additions needed to keep browsing smooth. PHP script can easily control the session's cookie which is being sent and control the whole session data. Sessions are always stored in a unique filename, either in a temporary folder or in a specific folder, if a script instructs to do so.

An easy to use ViewPager that adds an awesome set of custom swiping animations. Just change your ViewPagers to JazzyViewPagers and you're good to go! If you're looking at the name of the library and thinking "... so what does jazz have to do with it?" I'd like to direct you to the following definition that I found in a dictionary: jazz someone or something up: to make someone or something more exciting or sexy; to make someone or something appeal more to contemporary tastes. The aim of this library is to do exactly this: jazz up the normal, everyday ViewPager

I've included a pretty barebones apk to show what the TransitionEffect.Tablet animation does. The example app will get better, but this is just to get something in your hands quickly :D! This project was inspired by CyanogenMod's Trebuchet launcher. Animations Available The JazzyViewPager's animations are encapsulated in TransitionEffect. I'll be adding more, but if you can think of anything in particular, let me know by filing an "Enhancement" in the Issues section. public enum TransitionEffect { Standard, Tablet, CubeIn, CubeOut, Flip, Stack, ZoomIn, ZoomOut, RotateUp, RotateDown, Accordion } You can select your animation by calling private JazzyViewPager mJazzy; / ... / mJazzy.setTransitionEffect(TransitionEffect.); Modifying your PagerAdapter Due to the limitations of the ViewPager class (which JazzyViewPager is built upon) in order to get the animations to work correctly for more than 3 Views, you'll have to add the following to the instantiateItem method of your PagerAdapter. private JazzyViewPager mJazzy; / ... */ @Override public Object instantiateItem(ViewGroup container, final int position) { Object obj = super.instantiateItem(container, position); mJazzy.setObjectForPosition(obj, position); return obj; } Once your Object is registered with the JazzyViewPager, you're good to go!

fastmod is a fast partial replacement for a tool to assist you with large-scale codebase refactors, and it supports most of codemod's options. fastmod's major philosophical difference from codemod is that it is focused on improving the use case "I want to use interactive mode to make sure my regex is correct, and then I want to apply the regex everywhere". For this use case, it offers much better performance than codemod. Accordingly, fastmod does not support codemod's --start, --end, or --count options, nor does it support anything like codemod's Python API.

Examples

Let's say you're deprecating your use of the tag. From the command line, you might make progress by running: fastmod -m -d /home/jrosenstein/www --extensions php,html \ '(.*?)' \ '${2}' For each match of the regex, you'll be shown a colored diff and asked if you want to accept the change (the replacement of the tag with a ` tag), reject it, or edit the line in question in your $EDITORof choice. NOTE: Whereascodemoduses Python regexes,fastmoduses the Rust slightly different regex syntax and does not support look around or backreferences. In particular, use${1}instead of\1to get the contents of the first capture group, and use$$to write a literal $in the replacement string. See the regex crate's A consequence of this syntax is that the use of single quotes instead of double quotes around the replacement text is important, because the bashshell itself cares about the$character in double-quoted strings. If you must double-quote your input text, be careful to escape$characters properly! fastmodalso offers a usability improvement overcodemod: it accepts files or directories to process as extra positional arguments after the regex and substitution. For instance, the example above could have been rewritten as fastmod -m --extensions php,html \ '(.*?)' \ '${2}' \ /home/jrosenstein/www This makes it possible to usefastmodto process a list of files from somewhere else if needed. Note, however, thatfastmoddoes its own parallel directory traversal internally, so doingfind ... | xargs fastmod ...may be much slower than usingfastmod` by itself.

Requirements

fastmod is primarily supported on macOS and Linux. fastmod has also been reported to work reasonably well on Windows. The major portability concerns are 1) the use of $EDITOR with a fallback and 2) the console UI, which is descended from codemod's ncurses-based text coloring & screen clearing
