PHP Syntax




PHP Environment Start – End

syntax is a way to representation of PHP script.
Basically it gives the primary idea to specify the code format.
It also specify the area of a written code.
There are three ways to start PHP environment.

The most commonly and effective  PHP  syntax:

<?php
 echo "welcome to the world of php"; 
 ?>
In the given Example
It begin with (< ?php) and End with(? >).
echo statement is used to print the given string. Mandatory closing in(“ABCD”)double quotes.
Terminate the script with semicolon because semicolon is known as terminator.

Short or short-open tags look like this:

 <? 
 echo "welcome to the world of php";
 ?>
In the given above example..
We use Short tags. start and end with () respectively.
Declare the statement in between (), to display the output on browser
short open tags smoothly works on XAMPP server but Face problem on wamp server
if you are using  WAMP Server First you have to Set the short_open_tag setting in your php.ini file to on
HTML script tags:
<script language="PHP">
        echo "welcome to the world of php";
</script>
HTML script is also declare to start PHP environment.
