Description:
------------
When mb_ereg is passed certain data types as the $pattern argument it
will return int(1), i.e. a successful match, when in fact it has not
matched. This is shown by setting the $regs argument and looking at the
returned array which only contains one element which is bool(false).
Reproduce code:
---------------
<?php
$unset_var = 10;
unset ($unset_var);
$inputs = array(NULL, null, false, FALSE, "", '', @$undefined_var,
@$unset_var);
$iterator = 1;
foreach($inputs as $input) {
if(@is_array($mb_regs)){
$mb_regs = '';
}
echo "\n-- Iteration $iterator --\n";
echo "Without \$regs arg:\n";
var_dump( mb_ereg($input, 'hello, world') );
echo "With \$regs arg:\n";
var_dump(mb_ereg($input, 'hello, world', $mb_regs));
var_dump($mb_regs);
$iterator++;
};
?>
