token_get_all
Split given source into PHP tokens
(PHP 4 >= 4.2.0, PHP 5)
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.
For a list of parser tokens, see Appendix S, List of Parser Tokens, or use token_name() to translate a token value into its string representation.
Return Values
An array of token identifiers. Each individual token identifier is either
a single character (i.e.: ;, .,
>, !, etc...),
or a three element array containing the token index in element 0, the string
content of the original token in element 1 and the line number in element 2.
Examples
Example 2559. token_get_all() examples
<?php
$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 */'));
?>
