PHP Development Services for Website

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 Objects

Basic object-oriented programming functionality was added in PHP 3 and improved in PHP 4.
This allowed for PHP to gain further abstraction, making creative tasks easier for programmers using the language. Object handling was completely rewritten for PHP 5, expanding the feature set and enhancing performance.
In previous versions of PHP, objects were handled like value types. The drawback of this method was that code had to make heavy use of PHP’s “reference” variables if it wanted to modify an object it was passed rather than creating a copy of it. In the new approach, objects are referenced by handle, and not by value.

 

Implementations

The original, only complete and most widely used PHP implementation is powered by the Zend Engine and known simply as PHP. To disambiguate it from other implementations, it is sometimes unofficially called “Zend PHP”. The Zend Engine compiles PHP source code on-the-fly into an internal format that it can execute, thus it works as an interpreter. It is also the “reference implementation” of PHP, as PHP has no formal specification, and so the semantics of Zend PHP define the semantics of PHP. Due to the complex and nuanced semantics of PHP, defined by how Zend works, it is difficult for competing implementations to offer complete compatibility.

 

Licensing

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 group@php.net. You may indicate that your software works in conjunction with PHP by saying “Foo for PHP” instead of calling it “PHP Foo” or “phpfoo”.

 

Development and community

PHP includes various free and open-source libraries in its source distribution, or uses them in resulting PHP binary builds. PHP is fundamentally an Internet-aware system with built-in modules for accessing File Transfer Protocol (FTP) servers and many database servers, including PostgreSQL, MySQL, Microsoft SQL Server and SQLite (which is an embedded database), LDAP servers, and others. Numerous functions familiar to C programmers, such as those in the stdio family, are available in standard PHP builds.

 

Installation and configuration

There are two primary ways for adding support for PHP to a web server – as a native web server module, or as a CGI executable. PHP has a direct module interface called Server Application Programming Interface (SAPI), which is supported by many web servers including Apache HTTP Server, Microsoft IIS, Netscape (now defunct) and iPlanet. Some other web servers, such as OmniHTTPd, support the Internet Server Application Programming Interface (ISAPI), which is a Microsoft’s web server module interface. If PHP has no module support for a web server, it can always be used as a Common Gateway Interface (CGI) or FastCGI processor; in that case, the web server is configured to use PHP’s CGI executable to process all requests to PHP files.

 

Security

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;[103][104] 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.[111] 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.
