A critical part of application design is the way in which an application will be used and the reactions it will generate from users. The User Interface (UI) and User Experience (UX) is important in all application development, but especially in small, highly personal, hand-held devices that are depended upon often and typically used on the go.
When the UI and UX is right, your web & app will deliver a smoothly flowing, intuitive, productive, highly positive experience that will make users want to use it again and again.
PineSucceed’ team of acclaimed UI/UX designers define success as transforming application functionalities into a richly satisfying experience for users. Our designers create User Interfaces that are beautiful, easy to use, and easy to understand in any scale–from elegant, single-purpose microsites to powerful mobile or desktop-class applications.
PHP is free software released under the PHP License, which stipulates that:
Products derived from this software may not be called “PHP”, nor may “PHP” appear in their name, without prior written permission from email@example.com. You may indicate that your software works in conjunction with PHP by saying “Foo for PHP” instead of calling it “PHP Foo” or “phpfoo”.
In 2017, 3% of all vulnerabilities listed by the National Vulnerability Database were linked to PHP; [original research?] historically, about 30% of all vulnerabilities listed since 1996 in this database are linked to PHP. Technical security flaws of the language itself or of its core libraries are not frequent (22 in 2009, about 1% of the total although PHP applies to about 20% of programs listed). Recognizing that programmers make mistakes, some languages include taint checking to automatically detect the lack of input validation which induces many issues. Such a feature is being developed for PHP, but its inclusion into a release has been rejected several times in the past.
There are advanced protection patches such as Suhosin and Hardening-Patch, especially designed for web hosting environments.

The PHP interpreter only executes PHP code within its delimiters. Anything outside its delimiters is not processed by PHP, although non-PHP text is still subject to control structures described in PHP code. The most common delimiters are to close PHP sections. The shortened form <? also exists. This short delimiter makes script files less portable, since support for them can be disabled in the local PHP configuration and it is therefore discouraged; there is no recommendation against the echo short tag , in XHTML and other XML documents, creates correctly formed XML processing instructions.
This means that the resulting mixture of PHP code and other markup in the server-side file is itself well-formed XML.
Variables are prefixed with a dollar symbol, and a type does not need to be specified in advance. PHP 5 introduced type hinting that allows functions to force their parameters to be objects of a specific class, arrays, interfaces or callback functions. However, before PHP 7.0, type hints could not be used with scalar types such as integer or string.
Unlike function and class names, variable names are case sensitive. Both double-quoted (“”) and heredoc strings provide the ability to interpolate a variable’s value into the string.
PHP treats newlines as whitespace in the manner of a free-form language, and statements are terminated by a semicolon. PHP has three types of comment syntax: /* */ marks block and inline comments; // or # are used for one-line comments.
The echo statement is one of several facilities PHP provides to output text.
In terms of keywords and language syntax, PHP is similar to the C style syntax. if conditions, for and while loops, and function returns are similar in syntax to languages such as C, C++, C#, Java and Perl.
