just put    a  Link1    b  Link2     in your pass php and you will get your answer and do a double quotation in your link php    echo   lt a href  pass php link      a      gt Link 1 lt  a gt

All the above answers are correct  but I noticed something very important  Leaving a space between the variable and the equal sign might result in a problem  For example    variablename  value

You re passing link  a and link  b in the hrefs for A and B  respectively  They are treated as strings  not variables  The following should fix that for you   echo   lt a href  pass php link      a      gt Link 1 lt  a gt        and  echo   lt a href  pass php link      b      gt Link 2 lt  a gt      The value of  a also isn t included on pass php  I would suggest making a common variable file and include it on all necessary pages

In your link php your echo statement must be like this   echo   lt a href  pass php link      a     gt Link 1 lt  a gt    echo   lt a href  pass php link      b      gt Link 2 lt  a gt      Then in your pass php you cannot use  a because it was not initialized with your intended string value   You can directly compare it to a string like this   if   GET  link       Link1     Another way is to initialize the variable first to the same thing you did with link php  And  a much better way is to include the  a and  b variables in a single PHP file  then include that in all pages where you are going to use those variables as Tim Cooper mention on his post  You can also include this in a session
