How to combine backslash between two variables?

Question

I want to combine a backslash between two variables when passing them in function arguments so that they form a file path.

turbo_function($variable1.\.$variable2, $otherargument);

I'm sure the backslash should be escaped. I tried wrapping it in quotation marks and double quotes.

How to compile backslash with variables successfully?

Answer 1

Remove backslash with backslash!

Like this..

turbo_function($variable1."\\".$variable2, $otherargument);

Answer 2

• It must be a string
• This is an escape character, so it must be escaped inside the string.

Such:

$variable1 . "\\" . $variable2

Answer 3

, . :

$concatinatedVar = $variable1."\\".$variable2;
turbo_function($concatinatedVar , $otherargument);
