How can i concatenate the following css string in php without creating another variable or breaking the string?

Question

I have the following code:

$el = "<div style='padding: $padding'></div>";

The problem is i cannot write

$el = "<div style='padding: $paddingpx'></div>";

because $paddingpx would then be another variable.

And this will produce a wrong css value

$el = "<div style='padding: $padding px'></div>";

because if $padding = 20 then '20 px' is wrong and should be '20px'.

How do i concatenate 'px' to the above code. Note that the variable $padding is a value that i will receive from the $_POST action. I would like to know how i can concatenate 'px' with the padding style value without creating any further lines of code of breaking the string like so.

$el = "<div style='padding: $padding"."px".'></div>";

Thank you, MMK.

The whole purpose of this question is to address the concatenation problem and put everything in a single line of code without breaking the string. And the answer to it is curly braces around the PHP variable like so "<div style='padding: {$padding}px'></div>"; Thank you all. MMK — MMK

Add a curly brace like

$el = "<div style='padding: {$padding}px'></div>";

Any scalar variable, array element or object property with a string representation can be included via this syntax.

@Eugen Is not copy paste man, is the easiest way to do it. You don't invent PHP.

This code works as well.
There is some ways to using php code in other php string that contents are html.

$el = "<div style='padding: ".$padding."px'></div>";
