at the end it is saying bool.false when I run the script.

This is my code as I thought I followed along with the instructor. <?php $name = 'Tj'; $string_one = "Learning to display \"Hello $name!\" to the screen.\n"; $string_one = 'Learning to display'; $string_one.='" Hello '; $string_one.= $name; $string_one.= '!" to the screen.'; //$string_one = $string_one . "\n"; //prepend to a string //$string_one = 'I am ' . $string_one; echo $string_one;

$isReady = true; //var_dump($isReady); $isReady = false; //var_dump($isReady);

//var_dump(1 + "2");

$a = 10; $b = '10';

//var_dump($a == $b); //var_dump($a === $b);

var_dump($string_one == 'Learning to display "Hello Alena!" to the screen.'); ?>

Hi TJ,

Please see the formatting guidelines in the Markdown Cheatsheet to make your code more readable. It can be tricky to debug otherwise.

But the reason the var_dump is returning false is because your conditional expression evaluates to false.

You have defined $name = 'Tj' at the beginning of the script, but you are checking for "Alena" as the value of $name in your var_dump call.

Lengthy strings that have been concatenated over a number of lines can get confusing and it is easy to miss things. But when comparing variables and values, everything needs to be exactly correct.

Hope this helps.
