You should use either single quotes or double quotes in any associative
index. You do not need to use them for numeric indices.
$_SESSION['x_Email']
$_POST['loginName']
$form_html['button']
$count[1]
$item[7]
Don't forget that variables will not expand within single quotes. Use
double quotes if you have a variable in your associative index.
$_POST["filename{$i}"]
Again, not really an issue for numeric indices.
$input[$c]

Please note that an unquoted array key is now deprecated syntax. See

RE: [PHP] echo and Session Variables
Well, a stray define('myvar','foo') somewhere would make a mess of that.
It is safer to use $myarray['myvar']. Inside a quoted string you of
course shouldn't use the ''

RE: [PHP] echo and Session Variables
The single quotes in $_SESSION['myvar'] are not necessary. You're
reading an associative array in which a string is acting as a pointer to
the index.
Example..
$myarray = array ('myvar' => 'myvalue');
echo $myarray[myvar]; // prints out 'myvalue'

The issue is with the syntax you're using to refer to arrays within double
quotes.
echo "value=\"{$_SESSION[x_Email]}\"";

[PHP] echo and Session Variables
I was just wondering if there's a way to use echo with session variables. When I try to do this: it gives me this error: Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in /home/storings/public_html/uslogin.php on line 134 Am I doing something wrong or is there a better way to do this? I know that I could use printf() but is there a way to do it with echo and is accessing the session variables with $_SESSION[] the "right" way to do it?
