How to write classes in php code?

Question

PHP

I tried to display my divs via php, and everything would be fine, but only the first class in the div is taken into account. Those. if it looks like this:

if (isset($_POST['currentTier']) && strpos($_GET['type'], 'placements')===false) $description .= "<div id=details-2 class=col-12 col-xl-4 col-lg-12 mb-xl-5 mb-5><div class=d-flex b-skills><div class=height:70px;><div class=text-bold>Текущая лига:</div> <div class=text-primary> ".$tiers[$_POST['currentTier']]."</div></div></div></div></br>";

Then the first class will work at the output, and all classes that are registered after col-12 will not work.
In code it looks like this

Is there a way to make the other classes work?

Answer 1

We explain with a simple example how logical thinking can be used in programming.

$description = "<div id='details-2' class='col-12 col-xl-4 col-lg-12 mb-xl-5 mb-5'><div class='d-flex b-skills'><div class='height:70px;'><div class='text-bold'>";
echo $description,"\n";
echo addslashes($description);

We take our long-suffering word description and display it as it is. And - about a miracle! - all quotes are in place.
After that, we add the function of adding backslashes. And we see that they are added to the quotes .
From which we can make a logical conclusion that between the creation of the long-suffering description variable and the output of its contents to the screen, there is some shit code that, for some unknown reason, adds backslashes to it.
And discover for yourself the magic keys Ctrl-U
If you have problems with generating html, you need to look exactly what your code has generated , and not those beautiful things that the inspector diligently paints on it.

Quote all classes to single or double (need to be escaped)

if (isset($_POST['currentTier']) && strpos($_GET['type'], 'placements')===false) $description .= "<div id=details-2 class='col-12 col-xl-4 col-lg-12 mb-xl-5 mb-5'><div class='d-flex b-skills'><div class='height:70px;'><div class='text-bold'>Текущая лига:</div> <div class='text-primary'> ".$tiers[$_POST['currentTier']]."</div></div></div></div></br>";
