Question

I am using this snippet below, how can i add a second equal statement with an “and” so something like ($onevariable === $othervariable) and ($2variable ===$2othervariable)

  if ( $onevariable === $othervariable ) {
  require("file.php");
  }

Answer 1

This is fairly straight-forward, it’s just how you already wrote in your question:

if ( ($onevariable === $othervariable) and ($2variable === $2othervariable) ) {
    require("file.php");
}

See as well Logical Operators (PHP).

Note: $2variable is not a valid variable name, as well isn’t $2othervariable because they start with a number. But I think you get the idea from the example code.
