echo "Hello world!";

- This will output "Hello world!". The echo statement can be used to display various arrays, functions etc. HTML can also be embedded in an echo statement, replace any double-quotes that HTML would use with single-quotes.

print "Hello world!";

- The print statement is almost identical to the echo statement.

 

$foo = "Billy";
echo "My name is $foo.";

- This echo statement will output "My name is Billy.". It makes use of a variable.

 

$array['0'] = "Billy";
$array['1'] = "Sally";
echo "My name is $array['0'], my sister's name is $array['1'].";

- This echo statement will output "My name is Billy, my sister's name is Sally.". It makes use of variable arrays ($array[key]).

 

If you are still interested in learning some more PHP, feel free to wander over to http://www.tizag.com to pick up some more basic knowledge. If you would like to learn how to use more advanced PHP, wander over to http://www.php.net and take a look at the manual. Good luck!

Commenting

Requesting

<?php
$variable_get = $_GET['variable']; //requesting url configuration: index.php?variable=value
$variable_post = $_POST['variable']; //requesting form configuration, sent by form method post
$variable_req = $_REQUEST['variable']; //requesting from both get/post, will find one, and use that one
$variable_ses = $_SESSION['variable']; //session variable, define by $_SESSION['variable'] = "value";
$variable_coo = $_COOKIE['variable']; //cookie variable, define by using setcookie();
$variable_ser = $_SERVER['REMOTE_ADDR']; //will return user's IP using the server request method
?>

 

Arrays

<?php
$array = array(); //array with no values

$array[] = "value1"; //will set the 0 key to the $array variable

$array2 = array('value1','value2','value3'); //array with 3 true values
?>

 

Echo/Print

Difference between the two:

Even though print() and echo() are essentially interchangeable most of the time, there is a

substantial difference between them. While print() behaves like a function with its own

return value (although it is a language construct), echo() is actually a language construct that

has no return value and cannot, therefore, be used in an expression.

 

Using Echo/Print

<?php
echo constant; //will echo constant unless constant is defined
echo "string"; //will echo string with usage of double quotes
echo 'string'; //also a string using single quotes
echo $variable; //will echo the value of the variable $variable

//print
print constant; //will print constant unless constant is defined
print "string"; //same
print 'string'; //same
print $variable; //same
?>
