Security card Storage
Copy CodeThe code is as follows:
$this->load->model (' Admin/m_mibao ');
$data = Array ();
Generate Random Horizontal axis
$rand _str = $this->_rand_str (10);
$arr = Array ();
for ($k =0; $k {
for ($i = 1; $i < 9; $i + +)
{
$rand = $this->_rand_num (3);
Assign to all code containers
$arr [$rand _str{$k}. $i] = $rand;
}
}
$data [' code '] = serialize ($arr); Put information into storage after serialization
$data [' letter '] = $rand _str;
Avoid repeating serial numbers
while (TRUE)
{
$data [' card_num '] = $this->_rand_num (20);
Determine if the serial number is duplicated
if ($this->m_mibao->has_card_num ($data [' card_num ']) = = = 0)
{
Break
}
}
$data [' add_time '] = time;
$data [' user_id '] = $uid;
echo $this->mibao->insert ($data);
Secret card image generation
Copy CodeThe code is as follows:
That's the coordinates.
Public function Show ($user _id)
