Description:
------------
PDO debugDumpParams truncate query: 
http://stackoverflow.com/questions/29410151/why-pdo-debugdumpparams-truncate-query


Test script:
---------------
<?php
$dbh = new PDO('mysql:dbname=test;host=127.0.0.1', 'root');
$sth = $dbh->prepare("
    SELECT '
        Dumps the informations contained by a prepared statement directly on the output. It will provide the SQL query in use, the number of parameters used (Params), the list of parameters, with their name, type (paramtype) as an integer, their key name or position, and the position in the query (if this is supported by the PDO driver, otherwise, it will be -1).
        This is a debug function, which dump directly the data on the normal output.
        Tip:
        As with anything that outputs its result directly to the browser, the output-control functions can be used to capture the output of this function, and save it in a string (for example).
        This will only dumps the parameters in the statement at the moment of the dump. Extra parameters are not stored in the statement, and not displayed.
    '
");
$sth->execute();
$sth->debugDumpParams();

Actual result:
--------------

There should be an option to disable the truncation. And of course it should be possible to get the result as an array. At the moment the function is really useless for debugging.

php_stream_printf(), which writes these strings to the output buffer, has a maximum length for strings it interpolates. I switched to php_stream_write() for the query strings to resolve the issue. The fix was applied starting with PHP 7.0.
