Returns an array of PhpToken objects representing given code.

参数

code

The PHP source to parse.

范例

示例 #1 PhpToken::tokenize() example


<?php
$tokens = PhpToken::tokenize('<?php echo; ?>');

foreach ($tokens as $token) {
    echo "Line {$token->line}: {$token->getTokenName()} ('{$token->text}')", PHP_EOL;
}

以上例程会输出：

Line 1: T_OPEN_TAG ('<?php ')
Line 1: T_ECHO ('echo')
Line 1: ; (';')
Line 1: T_WHITESPACE (' ')
Line 1: T_CLOSE_TAG ('?>')

示例 #2 Extending PhpToken


<?php

class MyPhpToken extends PhpToken {
    public function getUpperText() {
        return strtoupper($this->text);
    }
}

$tokens = MyPhpToken::tokenize('<?php echo; ?>');
echo "'{$tokens[0]->getUpperText()}'";

以上例程会输出：

'<?PHP '
