print

  • Printing output of a string of characters can be done in a variety of ways in Ruby. The equivalent of PHP’s print construct is Ruby’s print method.

    PHP

    print "Hello World";
// => Hello World

    Ruby

    print "Hello World"
# => Hello World

    Ruby also has the puts method, which will append a newline to the output.

    PHP

    print "Hello World\n";
// => Hello World

    Ruby

    puts "Hello World"
# => Hello World

    To inspect the value of a variable in Ruby we can use the p method. This is similar to performing a var_export in PHP.

    PHP

    $myVar = array("hello", "world");
var_export($myVar);  
// => array (0 => 'hello', 1 => 'world')

    Ruby

    my_var = ["Hello", "world"]
p my_var
# => ["Hello", "world"]
