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.

T_ENCAPSED_AND_WHITESPACE is whitespace which intersects a group of tokens. For example, an "unexpected T_ENCAPSED_AND_WHITESPACE" error is produced by the following code:

<?php
$main_output_world
= 'snakes!';
echo(
'There are' 10 $main_output_world);
?>

Note the missing concatenation operator between the two strings leads to the whitespace error that is so named above. The concatenation operator instructs PHP to ignore the whitespace between the two code tokens (the so named "encapsed" data"), rather than parse it as a token itself.

The correct code would be:

<?php
$main_output_world
= 'snakes!';
echo(
'There are' . 10 . $main_output_world);
?>

Note the addition of the concatenation operator between each token.

T_ENCAPSED_AND_WHITESPACED is returned when parsing strings with evaluated content, like "some $value" or this example from the Strings reference page:

<?php
echo <<<EOT
My name is "$name". I am printing some $foo->foo.
Now, I am printing some
{$foo->bar[1]}.
This should print a capital 'A': \x41
EOT;
?>

This last example is tokenized as:
T_ECHO
  echo
T_WHITESPACE
  %20 (a space character)
T_START_HEREDOC
  <<
T_ENCAPSED_AND_WHITESPACE
  My name is "
T_VARIABLE
  $name
T_ENCAPSED_AND_WHITESPACE   
  ". I am printing some
T_VARIABLE   
  $foo
T_OBJECT_OPERATOR   
  ->
T_STRING   
  foo
T_ENCAPSED_AND_WHITESPACE   
  . Now, I am printing some
T_CURLY_OPEN   
  {
T_VARIABLE   
  $foo
T_OBJECT_OPERATOR   
  ->
T_STRING   
  bar
(terminal)
  [
T_LNUMBER   
  1
(terminal)
  ]
(terminal)
  }
T_ENCAPSED_AND_WHITESPACE   
  . This should print a capital 'A': \x41
T_END_HEREDOC
  EOT
(terminal)
  ;
