Anhang J. List of Parser Tokens
Various parts of the PHP language are represented internally by types like
T_SR. PHP outputs identifiers like this one in parse errors, like
"Parse error: unexpected T_SR, expecting ',' or ';' in script.php on line 10."
You're supposed to know what T_SR means. For everybody who doesn't
know that, here is a table with those identifiers, PHP-syntax and
references to the appropriate places in the manual.

if you get a parse error saying that there was an unexpected
T_ENCAPSED_AND_WHITESPACE, you've probably got an array within double
quoted strings being parsed incorrectly.
For example:
$foo =
$_GET['foo'];
echo "foo is $foo"; // works
fine
However,
echo "foo is $_GET['foo']"; // parse
error
Inside double-quoted strings, an identifier found within
square brackets (after a variable, of course) is parsed as a string index.
This identifier must be either a string, another variable, or a number.
Since the single-quote around foo doens't fit (to the parser, anyway) any
of these tokens, you get the parse error.
To remove the error,
remove the single quotes, OR use the curly-brace syntax (recommended, as
it's required for more complex substitution anyway).
echo "foo
is {$_GET['foo']}"; // works
echo "foo is $_GET[foo]";
// also works

echo "foo is $_GET[foo][2]"; // don't works
echo "foo is
{$_GET['foo'][2]}"; // works
echo "foo is
".$_GET[foo][2]; // works if "foo" is not a defined
constant

I got a "T_ENCAPSED_AND_WHITESPACE" parse error on one of my php
files, and did not understand why.
When I read your post about
this, I first of all tried the {} brackets idea, but found that it did not
work. I then removed all instances of [' '] and replaced them with [ ].
Then it worked.
