Echo

<?php 
echo "Hello World"; 

echo "This spans 
multiple lines. The newlines will be 
output as well"; 

echo "This spans\nmultiple lines. The newlines will be\noutput as well."; 

echo "Escaping characters is done \"Like this\"."; 

//You can use variables inside of an echo statement 
$foo = "foobar"; 
$bar = "barbaz"; 

echo "foo is $foo"; // foo is foobar 

// Using single quotes will print the variable name, not the value 
echo 'foo is $foo'; // foo is $foo 

// If you are not using any other characters, you can just echo variables 
echo $foo;          // foobar 
echo $foo,$bar;     // foobarbarbaz 

echo <<<END 
This uses the "here document" syntax to output 
multiple lines with $variable interpolation. Note 
that the here document terminator must appear on a 
line with just a semicolon no extra whitespace! 
END; 

// Because echo is not a function, following code is invalid. 
($some_var) ? echo('true'): echo('false'); 

// However, the following examples will work: 
($some_var) ? print('true'): print('false'); // print is a function 
echo $some_var ? 'true': 'false'; // changing the statement around 
?> 

echo() also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. 
I have <?=$foo?> foo.
