A Structured Document
To create a PHP page start with a text editor.

To properly structure a page, begin and end the document with:

<?php


?>

php Extention
If you have PHP inserted into your HTML and want the web browser to interpret it correctly, then you must save the file with a .php extension. Instead of index.html, it should be index.php if there is PHP code in the file.

Semicolons
Every statement in PHP ends with a semicolon.

Comments
PHP support three kinds of comment tags :

//
This is a one line comment
#
This is a Unix shell-style comment. It's also a one line comment
/* ..... */
Use this multi line comment if you need to.

Variables
A variable is a means of storing a value, such as text string "Hello World!" or the integer value 4. After varibles are initialized they can be reused throughout your code. In PHP you define a variable with the following form:

$variable_name = Value;

If you forget that dollar sign at the beginning, it will not work. Also, variable names are case-sensitive, so use the exact same capitalization when using a variable. The variables $a_number and $A_number are different variables.

There are a few rules that you need to follow when choosing a name for your PHP variables.

PHP variables must start with a letter or underscore "_".
PHP variables may only be comprised of alpha-numeric characters & underscores. a-z, A-Z, 0-9, or _ .
Variables with more than one word should be separated with underscores. $my_variable
Variables with more than one word can also be distinguished with capitalization. $myVariable

echo
The PHP function echo is a means of outputting text to the web browser.

echo "Hello world";

String Creation Heredoc

$my_string=<<<MY_STRING
Saint Anns School<br />
129 Pierrepont Street<br />
Brooklyn, NY 11201
MY_STRING;

There are a few very important things to remember when using heredoc:

Use <<< and some identifier that you choose to begin the heredoc. In this example MY_STRING is the identifier.
Repeat the identifier followed by a semicolon to end the heredoc string creation. In this example that was MY_STRING;
The closing sequence MY_STRING; must occur on a line by itself and cannot be indented!

Another thing to note is that when you output this multi-line string to a web page, it will NOT span multiple lines. To insert a carriage RETURN you need to use the <br /> tags contained inside the string. Here is the output made from the code above:
