PHP programs are saved in a file with extension “.php” ( we can use it in .html files also , that I will explain other posts ).
PHP scripts will be in between <?php and ?> tags.
<?php is the starting tag ( where our php program in the page starts ) and ?> ending tag ( where our php program ends ).
PHP programs are embedding in between html codes and we can use the html codes inside our php programs also.
Basically a PHP program page will look like
<h1>How a PHP program look like<h1>
/* Here is a block of PHP codes in page */
<h2> HTML portions </h2>
/* Here is another block of PHP code /*
Here we can see that we can use any number of blocks of PHP codes with a mixture of HTML codes in a page with starting and ending tags of PHP.
