PHP Parse Error

[kbjradmin]

i keep getting this error:
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/kbjr/public_html/tays_sis/contact/process.php on line 22

this is the line in question (line 22):

$msg = "Name: $_REQUEST['name']\nEmail: $_REQUEST['email']\nPurpose: $purpose\n\nMessage:\n$_REQUEST['message']"; 

please help, tell me if you need more info.

ok, here are the first 22 lines in the script:

<?php

$sendtoAddress = "yourname@yourdomain.com";
$subject = "Message From Website";
$headerFrom = "messaging@yourdomain.com";    # set to "user defined" to display the address given in the form.

##################################################################################
##########    This page contains the processing data for the        ##########
##########    contact system. DO NOT MODIFY BEYOND THIS POINT.    ##########
##################################################################################

if ( $headerFrom == "user defined" ){
    $headerFrom = $_REQUEST['email'] ;
}

function sendMessage($sendtoAddress,$headerFrom){
    if ( $_REQUEST['purpose'] == "other" ){
        $purpose = $_REQUEST['other'] ;
    }else{
        $purpose = $_REQUEST['purpose'] ;
    }
    $msg = "Name: $_REQUEST['name']\nEmail: $_REQUEST['email']\nPurpose: $purpose\n\nMessage:\n$_REQUEST['message']";

With the simple syntax for variable interpolation in double-quotes, you don't delimit array indices with quotes:

$msg = "Name: $_REQUEST[name]\n[...]"

Generally speaking, when the parser complains about an "unexpected T_", (the T_ prefix denotes a token) in a case like this, I'd start looking for an extraneous or missing character.

You should read up on variable parsing in the strings section of the PHP manual.

One more edit ><

Make sure the variables are set before using them. I get this error if the variable is undefined.
Edit:
I'm still wrong...It looks like indexes are the problem. If you replace $_REQUEST[...] with any other variable, it works, it's just the associative index. $_REQUEST[0] works, $name works, just not $_REQUEST['name']

from php.net:

<?php
// These examples are specific to using arrays inside of strings.
// When outside of a string, always quote array string keys and do not use
// {braces}.

// Show all errors
error_reporting(E_ALL);

$fruits = array('strawberry' => 'red', 'banana' => 'yellow');

// Works, but note that this works differently outside a string
echo "A banana is $fruits[banana].";

// Works
echo "A banana is {$fruits['banana']}.";

// Works, but PHP looks for a constant named banana first, as described below.
echo "A banana is {$fruits[banana]}.";

// Won't work, use braces.  This results in a parse error.
echo "A banana is $fruits['banana'].";

// Works
echo "A banana is " . $fruits['banana'] . ".";

// Works
echo "This square is $square->width meters broad.";

// Won't work. For a solution, see the complex syntax.
echo "This square is $square->width00 centimeters broad.";
?>

Actually, "$y/n" is perfectly valid and $y will interpolate properly. The parser is greedy but won't take characters that form an invalid identifier, like '/'. In other cases where a variable name is immediately followed by valid identifier characters ($foo="foo"; "$foobar";), use brackets to delimit the variable name ($foo="foo"; "${foo}bar";) or use complex syntax:

$foo=new Thing('bar', 'bam');
"I made a {$foo->name()} for {$_REQUEST['name']}.";

Edit:
If you're wondering why I mention "$y/n", it's because it was in an earlier version of the above post.

thank you for the help, it works now.
