[SOLVED] Backslashing in PHP

greens85 · July 20, 2009

Hi all,

I have the following code, I'm just wondering how I go about backslashing the quote so that it will display the name of the person logged in:

   <label>You are logged in as "<?php echo $_SESSION['username'] ?>"</label>   <a href="logout.php">Logout?</a>

obviously theres more code to it than this, but this is the line in question.... all this code is displayed via and echo statement, but it wont display the session name. I know this is because it isnt backslashed, but im not sure how to do this correctly...

can anyone help?

thanks

this is inside a bigger echo statement? you need to do it like this then:

echo '   <label>You are logged in as "'.$_SESSION['username'].'"</label>   <a href="logout.php">Logout?</a>';

If what rhodesa pointed out is not the case, then:

1) did you start session_start();?

2) does $_SESSION hold a variable username?

3) session name is not $_SESSION['username'];

Hi Rhodesa,

Yes it is inside a bigger echo statement, I tried the code you provided but it then starts to highlight as as a php keyword along with hightlighting the ampersands and also the < and />

I have provided the whole code, so hopefully to make it easier for you to see whats going on:

For large blocks of HTML you should just stop and start PHP...it makes things so much easier:

By the way, rhodesa, you missed that there was no semi-colon after $_SESSION['username']

By the way, rhodesa, you missed that there was no semi-colon after $_SESSION['username']

while it's good to use a semi-colon there, in this particular case it's optional
