    Glue together variable and string

    How do I glue together a variable with a string?

    $suffix = "px";

    $height = 14;

    I need to print "14px" widthout any whitespace inbetween 14 and px. How
    do I do it?

      The double-quotes are pointless here, but otherwise correct.

      If you wanted to use double quotes, an alternative is:

      $thc = "$suffix$height ";

      The OP should read: http://uk.php.net/manual/en/language.types.string.php

          So, bad replies should go uncorrected? Hopefully both the OP, and the person
          who replied with a nearly correct but not quite right answer, learned
          something.

          What's the point in self-destructing replies, by the way?

              opportunities that we answer and answer and answer and answer......... .

              give someone a fish he eats today - teach him to fish and he eats for a
              lifetime.

              Pointing out where the docs are can be an invaluable lesson. I have not
              yet come across a problem I can solve myself by simply RTM ( and google
              doesn't hurt).

                  Just pointless.

                  Using double-quotes in that scenario will just increase the parsing time. If
                  you want to concatenate two (mixed) variables into one string, just use the
                  "." operator. That will make an implicit variable casting of any numeric
                  (integer or float) variables to string, with no need to use any quotes or
                  explicit casting:

                  $thc = $height . $suffix;

                  And, BTW: KISS.
