boldlistingssourcecode

I want to do a box like this

but the bold text doesn't appear.

Edited:

\documentclass{article}
\usepackage{listings,xcolor,etoolbox,lmodern}
\definecolor{verbgray}{gray}{0.9}
\newcommand*\prompt{}% empty default
\lstnewenvironment{sh}{%
  % redefine bash prompt:
  \def\prompt{user@linux:\textasciitilde\$\space}%
  \lstset{backgroundcolor=\color{verbgray},
    frame=single,
    framerule=1pt,
    basicstyle=\ttfamily,
    columns=fullflexible,
    escapechar=@
  }%
}{}
\begin{document}
    \begin{sh}
    @\prompt\space\textbf{date}@
    Thu Oct 25 13:51:54 EDT 2007
    \end{sh}
\end{document}

Here's a slightly modified version of what you wrote:

\documentclass{article}
\usepackage{lmodern}
\usepackage{listings,xcolor,etoolbox}
\definecolor{verbgray}{gray}{0.9}
\newcommand*\prompt{}% empty default
\lstnewenvironment{sh}{%
  % redefine bash prompt:
  \def\prompt{user@linux:\textasciitilde\$\space}%
  \lstset{backgroundcolor=\color{verbgray},
    frame=single,
    framerule=1pt,
    basicstyle=\ttfamily,
    columns=fullflexible,
    escapechar=@
  }%
}{}
% patch \lst@NewLine:
\makeatletter
\patchcmd\lst@NewLine
  {\hbox{}}% search
  {\hbox{}\prompt}% replace
  {}% success
  {}% failure
\makeatother
\begin{document}
    \begin{sh}
    @\textbf{date}@
    Thu Oct 25 13:51:54 EDT 2007
    \end{sh}
\end{document}

You need fonts which will allow bold when creating ttfamily. Hence the loading of

\usepackage{lmodern}

Alternate Solution:

You could also use the the courier font form ttfamily with bfseries or how to enable bold in fixed width font:

enter image description here

\documentclass[border=2pt]{standalone}
\usepackage{listings}

\lstset{language=C,
    basicstyle=\ttfamily,
    keywordstyle=\bfseries,
    showstringspaces=false,
    morekeywords={include, printf}
}

\begin{document}
\begin{lstlisting}
    /* Prints Hello World */

    #include <stdio.h>
    
    int main(void) {
       printf("Hello World!");
       return 0;
    }
\end{lstlisting}

\hrule
\renewcommand{\ttdefault}{pcr}
\begin{lstlisting}
    /* Prints Hello World */

    #include <stdio.h>
    
    int main(void) {
       printf("Hello World!");
       return 0;
    }
\end{lstlisting}
\end{document}

[Tex/LaTex] good definition for highlighting PHP code in listings

listings provides lots of options to color/customize the format of the style to your likings. Of course you should choose php as a language.

This may be a starting point:

\documentclass{article}
\usepackage{listings,xcolor}
\usepackage{inconsolata}

\definecolor{dkgreen}{rgb}{0,.6,0}
\definecolor{dkblue}{rgb}{0,0,.6}
\definecolor{dkyellow}{cmyk}{0,0,.8,.3}

\lstset{
  language        = php,
  basicstyle      = \small\ttfamily,
  keywordstyle    = \color{dkblue},
  stringstyle     = \color{red},
  identifierstyle = \color{dkgreen},
  commentstyle    = \color{gray},
  emph            =[1]{php},
  emphstyle       =[1]\color{black},
  emph            =[2]{if,and,or,else},
  emphstyle       =[2]\color{dkyellow}}

\begin{document}

\begin{lstlisting}
<?php
/* this is a stupid example */
$username = $_POST["username"];
$passwort = $_POST["passwort"];

$pass = md5($passwort);

// another comment
if($username=="Andavos" and
$pass=="fd0d9cdefd5d42dfa36c74a449aa8214")
   {
   echo "Herzlich Willkommen";
   }
else
   {
   echo "Login Fehlgeschlagen";
   }
?>
\end{lstlisting}

\end{document}
