PHP - output values of a variable

I am a newbie to php. I am working on a existing wordpress site. I want to print the values of a variable $post as output. What is the equivalent of Java's System.out.print in php.

While googling i found the same, system.out.print for php but its not working.

-- Thanks

You can use echo to print something: docs

$_POST is an array, if you want to examine its value for debug purposes use var_dump (docs):

var_dump($_POST);

To access array's elements, use square brackets: $_POST['index']. PHP arrays may be associative, which means they are indexed not only by numbers, but also by strings. $_POST is a pure associative array, indexed only with strings.

To print POST parameter called username use this code:

echo $_POST['username'];

or

echo($_POST['username']);

Both will work because echo is not a function, but a language construct (see docs linked above).

PHP's echo construct is probably what you want.

<?php echo $_POST['variable']; ?>

where variable is the name of the form element.

printf("var = %s", $var);

or

echo $var;

or (for objects, arrays, etc)

print_r($_POST);

or 

var_dump($_POST);

Check php.net for more!
