You can embed a variable into a double quoted string like my first example  or you can use concantenation the period  like in my second example   echo   lt a href   http   www whatever com  param   gt Click Here lt  a gt     echo   lt a href  http   www whatever com      param      gt Click Here lt  a gt     Notice that I escaped the double quotes inside my first example using a backslash

I recommend using the short   instead of    If you do so  you wont longer have to escape the double quote        In that case you would write  echo   lt a href  http   www whatever com     param     gt Click Here lt  a gt      But look onto nicolaas  answer  what you really should do  to learn how to produce cleaner code

You can do it a number of ways  depending on the type of quotes you use    echo   lt a href  http   www whatever com  param  gt Click here lt  a gt    echo   lt a href  http   www whatever com   param   gt Click here lt  a gt    echo   lt a href  http   www whatever com      param      gt Click here lt  a gt    echo   lt a href   http   www whatever com  param   gt Click here lt  a gt      Double quotes allow for variables in the middle of the string  where as single quotes are string literals and  as such  interpret everything as a string of characters -- nothing more -- not even  n will be expanded to mean the new line character  it will just be the characters   and n in sequence   You need to be careful about your use of whichever type of quoting you decide   You can t use double quotes inside a double quoted string  as in your example  as you ll be ending the string early  which isn t what you want   You can escape the inner double quotes  however  by adding a backslash   On a separate note  you might need to be careful about XSS attacks when printing unsafe variables  populated by the user  out to the browser

There s a shorthand-type way to do this that I have been using recently  This might need to be configured  but it should work in most mainline PHP installations  If you re storing the link in a PHP variable  you can do it in the following manner based off the OP    lt html gt     lt body gt       lt  php        link    http   www google com         gt       lt a href   lt     link   gt   gt Click here to go to Google  lt  a gt     lt  body gt   lt  html gt    This will evaluate the variable as a string  in essence shorthand for echo  link

Well  for starters  you might not wanna overuse echo  because  as is the problem in your case  you can very easily make mistakes on quotation marks   This would fix your problem   echo   lt a href   http   www whatever com  param   gt Click Here lt  a gt      but you should really do this   lt  php    param    test     gt   lt a href  http   www whatever com  lt  php echo  param    gt   gt Click Here lt  a gt
