PHP File Creation Tips

PHP files may contain text, HTML and script blocks. But remember, PHP file has the following extensions:

  • .php
  • .php3
  • .phtml

You must have to use any of the three extensions. Most new program, don't care it and they face problems. So, remember, any types of PHP file must be .php or .php3 or .phtml extensions.

For example, if you write a "Hellow World" program using php, then the file name may look like the followings:

  • Hello_World.php

Where to Loacate PHP Files

All the PHP files are resided into htdocs folder. If you successfully installed PHP, Apache server then in your installation directory, you will find a folder named as htdocs. All of your PHP files must be located in that folder.

PHP Script's Basic Starting and Ending Tips

All PHP code block starts with a <?php tag and ends with ?> tag. This is the standard tags. Some servers also support shorterhand tags (<? for starting tag and ?> for ending tag). But it's a best idea to use the standarded tag set (i.e. <?php and ?> for starting and ending tag) .



// php code block


PHP Script's Commenting Tips

Sometimes, you need to insert comment into your code. To insert comment use " // " for single line comment and for multiple lines comment use " /* " and " */ " and put the comment block in between them.



// single line comment

   multiple lines of comment
   multiple lines of comment



PHP Code Line Ending Tips

Each code line in PHP must be ended with a semicolon ( ; ). This semicolon is actually a separator and it is used to distinguish one set of instructions form another sets of instructions.

The new programmer often do mistake to put a semicolon at the end of the code line and may find undesirable output. So, always to put semicolon in each line code end.



    echo "Hello World!!";


PHP Variables Tips

All PHP variables must starts with a $ sign. Variables are used for storing values, such as numbers, strings or function results. New programmer very often do mistakes to put the sing of each variables and if they do then the code may not work. After the $ sign, the variable name located. Variable name has some naming rules:

  • Variable names must be started with any letter or an underscore (" _ ")
  • Variable names can contain only alpha-numeric characters (a-z, A-Z, 0-9) and underscore (" _ ")
  • No space is allowed into the variable names

Example of variables:

  • $a
  • $my_number
  • $my_string
  • $x1

String is used to store and manipulate a piece of text. All the strings of PHP are located between " and ".


    echo "Hello World!!";
