    In any computer programming, variable interpolation is the process of evaluating an expression or string literal containing one or more variables, yielding a result in which the variables are replaced with their corresponding values in memory.

    This is , in simple, use of variable for printing or evaluation.
    Answer is same for all programming languages including PHP.

    Languages that support variable interpolation include Perl, PHP, Ruby, Tcl, and most Unix shells. In these languages, variable interpolation only occurs when the string literal is double-quoted, but not when it is single-quoted. The variables are recognized because variables start with a sigil (typically "$") in these languages.

    Variable interpolation is adding variables in between a string data.PHP will parse the interpolated variables and replace the variables with its value while processing the string data.

    the interpolated variables and replace the variable with its value while processing the string data. The variable parsing is allowed with the string data enclosed with double quotes or with heredocs.
