Question

I want to count the curly brackets in a PHP source code, so i can eventually find the end of a method/function in the given source code.

I was adviced to use the token_get_all() function for this job. But for some reason it isn’t splitting the given source into tokens.

I’m using the following code to test it:

<?php
$str = 'class someClass{
    public $var1;
    private $var2 = null;

    public function func1 ( $someVar )
    {
        echo $someVar;
    }

    public function func2 ( )
    {
        return false;
    }
}';

$bla = token_get_all ( $str );

echo '<pre>';
print_r ( $bla );
echo '</pre>';
?>

But this results in:

Array
(
    [0] => 311
    [1] => class someClass{
    public $var1;
    private $var2 = null;

    public function func1 ( $someVar )
    {
        echo $someVar;
    }

    public function func2 ( )
    {
        return false;
    }
}
    [2] => 1
)

So right now i’m kinda stuck with this. Why doesn’t the token_get_all() tokenize the given source code..?

Answer 1

Because the parser starts in HTML context (just like PHP itself), so the entire string you have passed to token_get_all is actually a single HTML token. You need to add <?php at the start of your $str.
