token_get_all
(PHP 4 >= 4.2.0, PHP 5)
token_get_all -- Split given source into PHP tokens
Description
array
token_get_all ( string source)
token_get_all() parses the given source
string into PHP language tokens using the Zend engine's lexical scanner.
The function returns an array of token identifiers. Each individual token
identifier is either a single character (i.e.: ;,
., >, !, etc...),
or a two element array containing the token index in element 0, and the string
content of the original token in element 1.
For a list of parser tokens, see 附录 P, or use
token_name() to translate a token value into its string
representation.

<?php
$tokens = token_get_all('<?php'); // => array(array(T_OPEN_TAG, '<?'));
$tokens = token_get_all('<?php echo; ?>'); /* => array(
array(T_OPEN_TAG, '<?php'),
array(T_ECHO, 'echo'),
';',
array(T_CLOSE_TAG, '?>') ); */
/* Note in the following example that the string is parsed as T_INLINE_HTML
rather than the otherwise expected T_COMMENT (T_ML_COMMENT in PHP <5).
This is because no open/close tags were used in the "code" provided.
This would be equivalent to putting a comment outside of <?php ?> tags in a normal file. */
$tokens = token_get_all('/* comment */'); // => array(array(T_INLINE_HTML, '/* comment */'));
?>
