Hi,

I spent an hour to understand why this simple code did not work for me:

// $functions: an array of the Db specific functions I care of.
// they are in form 'connect', 'query' etc...



$existing = get_defined_functions();
foreach($functions as $k=>$v) {
   $f = $dbms.$v;
   printf("%s $f<BR>", in_array($f, $existing['internal']) ? '+' : '-');
}



It did not return me anything at all, although it should.

The problem was:

get_defined_functions() returns a two dimensional array, in which all the values (functions) are having a (whitespace?) 'ORD(0)' at the end.

you can check it with this:



$func = get_defined_functions();

echo '<PRE>';
foreach($func['internal'] as $k=>$v) {
   printf("ASCII: '%d' \tvalue: '%s'\n", ord(substr($v, -1)), $v);
}
echo '</PRE>';



// the returns the following:

ASCII: '0' 	value: 'zend_version'
ASCII: '0' 	value: 'func_num_args'
ASCII: '0' 	value: 'func_get_arg'


and so on...

I believe that's a bug, no?
