How to use single quotes in single quotes?

Question

Can someone explain how to make this code work?

echo '<div id="panel1-under">Welcome <?php echo "$_SESSION['username']"; ?></div>'; 

I tried to remove single quotes ( echo '<div id="panel1-under">Welcome <?php echo "$_SESSION[username]"; ?></div>'; ) but it does not work.

Answer 1

 echo "<div id=\"panel1-under\">Welcome ".$_SESSION['username']."</div>"; 

or

 echo '<div id="panel1-under">Welcome '.$_SESSION['username'].'</div>'; 

Short description:

• You do not need to re-open the tags inside the String echo ("...")
• What I did here is pass the "Greetings" string, combined with $ _SESSION ['username'] and "" (which the statement does.)

• PHP is even smart enough to detect variables inside a PHP string and evaluate them:

  $ variablename = "Andrew";

  echo "Hello $ variablename, welcome";

=> Hello Andrew, welcome

Additional Information: PHP.net - echo

Answer 2

You need to combine strings and variables.

 echo '<div id="panel1-under">Welcome ' . $_SESSION['username'] . '</div>'; 

Answer 3

Variable expansion does not work inside single quotes. You can do it:

 echo "<div id=\"panel1-under\">Welcome {$_SESSION['username']}</div>"; 

or

 echo '<div id="panel1-under">Welcome ' . $_SESSION['username'] . '</div>'; 

Answer 4

In single quotes, variable names are not parsed, as in double quotes. If you want to use single quotes here, you will need to use the string concatenation operator,. :

 echo '<div id="panel1-under">Welcome <?php echo "'.$_SESSION['username'].'"; ?></div>'; 

By the way, the answer to the question in the header is that to use a literal single quote inside a single quote string, you avoid the single quote using a backslash:

 echo 'Here is a single-quote: \''; 

Answer 5

Generally speaking, to use a single quote inside a string using a single quote as a delimiter, just avoid a single quote inside a string

 echo 'That\ all, folks'; 

It is not clear what the purpose of your code is.

 echo '<div id="panel1-under">Welcome <?php echo "$_SESSION['username']"; ?></div>'; 

Since you are already using PHP code, <?php echo not required. If you are trying to display the contents of a session variable, you can use

 echo '<div id="panel1-under">Welcome ' . $_SESSION['username'] . '</div>'; 

Answer 6

Use the following code

 $data = $session['user']; echo "a big string and $data thats simple"
