1Why on Earth would you do that? The only reason is to execute user input and that opens you up, if you are a beginner, as it seems you are, to a world of pain.CodeAngry– CodeAngry2014-05-15 09:44:42 +00:00Commented May 15, 2014 at 9:44

You need to use a ternary operator.
Example:
$html = 'blabla' . ($a == $b ? 'write something' : 'or something else');

You don't even know what he's trying to do. How can you give an answer?

He's trying to add an if statement in the middle of a string. This is the best way to do it (according to me).
MrWhite
You will need to put parentheses around the ternary statement, otherwise you will not get the expected result. In the above code (without parentheses),
'blabla' . ($a == $b) is seen as the expression (not ($a == $b)), since . (string concatenation) has a higher precedence than ?: (ternary).use append again to string and use == to compare like
$html = 'blabla';
if($a == $b){
$html .='yes';
}
or use ternary operator like @Viktor Svensson answer

Hi.. I need that IF function inside the html variable
You probably want to do something like this.
<?php
$html = 'Your order was ';
if ($order->status === 'success') { // I don't know just doing something random
$html .= ' successful';
} else {
$html .= ' unsuccessful';
}
