I am having a hard time getting my strings to match in my if statement. What am I missing?
<?php
$name = 'Alena';
$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);
//($string_one == 'Learning to display "Hello Alena!" to the screen.');
if ($string_one == 'I am Learning to display "Hello Alena!" to the screen.') {
echo 'the values match';
} elseif ($string_one == "") {
echo '$string_one is empty';
} else {
echo 'the values DO NOT match';
}
?>
Thanks,

Either add a newline on line 29, or remove line 8, either will allow them to match.

Front End Web Development Techdegree Graduate 21,177 PointsThanks a lot Steven!!! That worked perfectly!!! Here is the updated code:
<?php
$name = 'Alena';
$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);
//($string_one == 'Learning to display "Hello Alena!" to the screen.');
if ($string_one == 'I am Learning to display "Hello Alena!" to the screen.' . "\n") {
echo 'the values match';
} elseif ($string_one == "") {
echo '$string_one is empty';
} else {
echo 'the values DO NOT match';
}
?>

Front End Web Development Techdegree Graduate 21,177 PointsHi Steven,
I have added a new line on line 29, but I am having the same problem.
Here is the code that I have:
I have also tried concatenating the string with a new line and I still have the same problem.
What am I missing?
Thanks,

231,236 PointsWhen using single quotes, the escape sequence is not recognized. So
'\n'
actually contains two characters, a backslash and a normal letter "n".If you use double quotes (
"\n"
) as you did on line 8, you'll get a single newline character and a match.
