Not sure what's wrong with my code?

<?php $name = 'Umar'; $string_one = "Learning to display \"Hello $name\" to the screen."; $string_one = 'Learning to display "Hello ' . $name . " to the screen."; //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($string_one == 'Learning to display "Hello Umar" to the screen.'); if ($string_one == 'Learning to display "Hello Umar" to the screen'); { echo 'The values mathch'; } elseif ($string_one == "") { echo '$string_one is empty';

there were a couple of things the single quotes mixed with double quotes, as you were breaking the string it would then throw an error.

your variable:

$string_one = "Learning to display "Hello $name"\ to the screen.";

updated variable: I would output the variable with concatenation, so you add single quotes around the double quotes:

$string_one = "Learning to display " . '"' . 'Hello' . ' ' . $name . '"' . " to the screen.";

Also it won't match as the string output in in $string_one has a full stop in it where in the conditional it doesn't. The following conditional will be commented out due to it being on the same line as the var_dump():

There is also one more thing to be weary of and that is the conditional ending with a semi colon before the curly bracket which will need to be removed.

//var_dump($string_one == 'Learning to display "Hello Umar" to the screen.'); if ($string_one == 'Learning to display "Hello Umar" to the screen');

Updated code below to help you see the picture:

<?php 

$name = 'Umar'; 


$string_one = "Learning to display " . '"' . 'Hello' . ' ' . $name . '"' . " to the screen.";

//$string_one = 'Learning to display "Hello ' . $name . " to the screen."; //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($string_one == 'Learning to display "Hello Umar" to the screen.');

if ($string_one == 'Learning to display "Hello Umar" to the screen.') {

    echo 'The values mathch'; 

} elseif ($string_one == "") { echo '$string_one is empty';

} else { echo 'The values DO NOT match'; }
