token_get_all — Split given source into PHP tokens
说明
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 解析器代号列表, or use token_name() to translate a token value into its string representation.
参数

-
The PHP source to parse.
返回值
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.
范例
Example#1 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 */'));
?>
