A PHP is a hypertext preprocessor and it is widely used scripting language, which was designed for the purpose of web development for producing dynamic web pages. For this same purpose, a PHP code is embedded inside the HTML source document. The web server along with a processor module, which generates web page, will interpret this document. Knowing how to run PHP can be useful for people using the scripting language.
PHP is a general-purpose programming language, a PHP code will be processed by an interpreter application inside the command line. This will be done while performing the desired operation of the operating system and producing a program output from the standard channel of output. PHP can function as the graphical language as well. This PHP is available as a processor for most of the modern web servers and as a standalone interpreter for some of the operating systems and platforms for computing. PHP is a scripting language, which is well suited for the server-side web developers where this PHP runs on the web server. A PHP code is always executed on the runtime of PHP, for creating dynamic web page content. Sometimes it is used for the command-line scripting and the client side applications for GUI. PHP can be easily deployed on any of the web server, operating systems and platforms and one can use it for managing the relational database system. The PHP group allows the use of this software for free and will give complete source to the user for building, customizing and extending the language for their own use.
A PHP on the primary level will act as a filter, it will take input from the file or stream containing text and outputs on another stream of data and the output will mostly be in HTML. According to the National Vulnerability Database all the vulnerabilities will be stored in the computer software. Most of the vulnerabilities that are related to PHP can be easily exploited remotely. They can let the crackers to come in and destroy or steal data from the data source, which is linked to the web server. These vulnerabilities can increase if one does not follow the programming rules. There can be technical security flaws inside the language or the core libraries may not be frequent causing vulnerability in the language. One must recognize that the programmers cannot be trusted and some of the languages will have the taint checking for detecting the lack of validation. This similar feature is being developed for PHP, but the inclusion of release has been rejected many times in the past.
For hosting PHP application on a server, it will require a constant and careful attention for dealing the security risks. There are some advanced protection patches like Suhosin and Hardening patches, which are designed for the environment of web hosting. PHP has many base functions and ‘n’ number of via extensions. All these functions are always well documented on the PHP site; however, the built-in library will have a huge variety of inconsistencies and naming conventions. Currently PHP has no functions for threading the program although, it does support the operation of multiprocess programming on the system of POSIX. Here are some simple steps on how to run PHP.
How to run PHP file without the extension .PHP
- First you will have to open the FTP file, which is the file transfer protocol. Open this program and start typing your username and password for logging inside the root directory of the website. Now you will have to locate the .htaccess file and then download it on your computer. If you do not find the .htaccess file inside the root directory, then you will have to open the text editor and make a file named ‘web.htaccess’.
- Now you can open the file .htaccess or the new file that you have just created. At the end, beneath the code you will find this file, start typing ‘addtypeapplication/x-httpd-PHP.htm.html’ and then press the ‘enter’ button.
- Start typing ‘addhandler x-httpd-PHP.htm.html’ on a new line. Save the file properly and then you can close the text editor.
- Now, you will have to upload the file from the FTP program, in the root directory, by overwriting the existing file .htaccess if required. If you have created the ‘web.htaccess’ file, then upload that file and right click on the file, select the option ‘rename’. You will have to delete the web portion from the name so that it only reads .htaccess, and then you can click ‘ok’.
- Open the web browser and direct this file to any HTML or HTM page where you wish to execute the PHP code. The new .htaccess file will start working immediately or the code may start after sometime, depending on the service of your web hosting. If you are hosting your own web browser, then restart it for starting the PHP code in HTML or HTM files.
Tips and Warnings:
- Always remember to back up your .htaccess file before you start making any changes in it.
- You will have to rename the ‘web.htaccess’ file to ‘.htaccess’ after you have uploaded it on the web server.
- If you have an existing file .htaccess then add the new file to this, but always remember that you must not overwrite the existing file or the other settings might stop working. You must always be careful with your .htaccess file and take help from your host if you are facing any problems.
- Anything inside your HTML files, which starts with <? will be executed in the PHP file format. If it is present in your file due to some other reasons, like for XML tag, then you will have to echo all the lines for preventing errors. For instance you can type this code
<?PHP echo ‘<?xml version=”1.0” encoding=”IUFF-8”?>’;?>
