PRINT(3)								 1								  PRINT(3)

print - Output a string

SYNOPSIS
       int print (string  $arg)

DESCRIPTION
	Outputs $arg.

       print is not actually a real function (it is a language construct) so you are not required to use parentheses with its argument list.

PARAMETERS
	      o $arg
		- The input data.

RETURN VALUES
	Returns 1, always.

EXAMPLES
       Example #1

	      print examples

	      <?php
	      print("Hello World");

	      print "print() also works without parentheses.";

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

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

	      print "escaping characters is done "Like this".";

	      // You can use variables inside a print statement
	      $foo = "foobar";
	      $bar = "barbaz";

	      print "foo is $foo"; // foo is foobar

	      // You can also use arrays
	      $bar = array("value" => "foo");

	      print "this is {$bar['value']} !"; // this is foo !

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

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

	      print <<<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;
	      ?>

NOTES
       Note

	      Because this is a language construct and not a function, it cannot be called using variable functions.
