Значення, що повертаються
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.

Приклад #1 token_get_all() example
<?php
$tokens = token_get_all('<?php echo; ?>');
foreach ($tokens as $token) {
if (is_array($token)) {
echo "Line {$token[2]}: ", token_name($token[0]), " ('{$token[1]}')", PHP_EOL;
}
}
?>

Приклад #2 token_get_all() incorrect usage example
<?php
$tokens = token_get_all('/* comment */');
foreach ($tokens as $token) {
if (is_array($token)) {
echo "Line {$token[2]}: ", token_name($token[0]), " ('{$token[1]}')", PHP_EOL;
}
}
?>
Поданий вище приклад виведе щось
схоже на:
Line 1: T_INLINE_HTML ('/* comment */')
Note in the previous example that the string is parsed as
T_INLINE_HTML rather than the expected
T_COMMENT. This is because no open tag was used in the
code provided. This would be equivalent to putting a comment outside of the
PHP tags in a normal file.
Приклад #3
token_get_all() on a class using a reserved word example
<?php
$source = <<<'code'
<?php
class A
{
const PUBLIC = 1;
}
code;
$tokens = token_get_all($source, TOKEN_PARSE);
foreach ($tokens as $token) {
if (is_array($token)) {
echo token_name($token[0]) , PHP_EOL;
}
}
?>
Поданий вище приклад виведе щось
схоже на:
T_OPEN_TAG
T_WHITESPACE
T_CLASS
T_WHITESPACE
T_STRING
T_CONST
T_WHITESPACE
T_STRING
T_LNUMBER
Without the
TOKEN_PARSE flag, the penultimate
token (
T_STRING) would have been
T_PUBLIC.
