Description of problem:
When using the prepare() command of the DB object from PEAR, the
statement is parsed incorrectly, and '?' components are not identified.
When debugging thruogh PEAR's source, I found the error to be created
on line 990 of DB/comon.php. The cause for this appears to be in line
780 of the same file, where print_r($tokens) shows the expected
contents for $tokens (an array of strings), however the simple code:

foreach ($tokens as $t) echo $t;

gives me "Array Array Array Array Array" (for a 5-component query)
This is a rather weird behavior, which may indice an internal PHP bug.
Also, previous version(4.3.9-3) had the exact same code for this
function, and worked perfectly, indicating that the problem may not be
in PEAR itself.

Version-Release number of selected component (if applicable):
php-4.3.10-3.2

How reproducible:
Always

Steps to Reproduce:
1. Execute the following, changing the query and database DSN to a
database you already have:
<?
    require_once('DB.php');
 
    // Convenience debug function
    function db_check_pretty_die($o) {
        if (DB::isError($o)) {
            die('<BR><span style="color: red;">'
                .' <span style="font-weight: bold;">Error
message:</span> '.$o->getMessage().'<BR>'
                .' <span style="font-weight: bold;">User info:</span>
'. $o->getUserInfo().'<BR>'
                .'</span><BR><BR>'
                .'<span style="font-size: 16px; font-weight:
bolder;">Backtrace:</span><BR>'
                .'<pre>'.print_r(debug_backtrace(),true).'</pre>');
        }
    }
 
    // Connect to database
    $dsn = "pgsql://user:pass@/db";
    $db = DB::connect($dsn, true);
    db_check_pretty_die($db);
    $db->setFetchMode(DB_FETCHMODE_ASSOC);
                                                                     
          
    // This is where the incorrect values are detected
    $st = $db->prepare('SELECT * FROM data WHERE iddatum=? AND hidden=?');
    $data = array(1234, false);
     
    // This is where the error is reported, when count($data) doesn't
match
    //the number of detected question marks
    $res = $db->execute($st, $data);
    db_check_pretty_die($res);
    $row = $res->fetchRow();
 
?>

Actual Results:  The following output was shown:
-------------
Error message: DB Error: mismatch
User info: Array Array Array Array Array


Backtrace:

Array
(
    [0] => Array
        (
            [file] => /var/www/html/test.php
            [line] => 28
            [function] => db_check_pretty_die
        )

)
-----------


Expected Results:  The query should be executed and a row should be
retrieved from the result set.

Additional info:

Didn't happen in 4.3.9-3.
