token_get_all — Split given source into PHP tokens
$source
[, int $flags
= 0
] )
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 Lista semnelor interpretorului, or use token_name() to translate a token value into its string representation.
source
The PHP source to parse.
flags
Valid flags:
TOKEN_PARSE
- Recognises the ability to use
reserved words in specific contexts.
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.

Example #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;
}
}
?>
Exemplul de mai sus va afișa ceva similar cu:
Line 1: T_OPEN_TAG ('<?php ') Line 1: T_ECHO ('echo') Line 1: T_WHITESPACE (' ') Line 1: T_CLOSE_TAG ('?>')
Example #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;
}
}
?>
Exemplul de mai sus va afișa ceva similar cu:
Line 1: T_INLINE_HTML ('/* comment */')
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.
Example #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;
}
}
?>
Exemplul de mai sus va afișa ceva similar cu:
T_OPEN_TAG T_WHITESPACE T_CLASS T_WHITESPACE T_STRING T_CONST T_WHITESPACE T_STRING T_LNUMBER
TOKEN_PARSE
flag, the penultimate
token (T_STRING
) would have been
T_PUBLIC
.
