inserting an array - php

Question

I have the following array that I want to insert into the table with the fields groupi_id, application_id and grant_id
the array is
array(
'ApplicationsGrant' => array(
'group_id' => array(
(int) 0 => '72',
(int) 1 => '72'
),
'application_id' => array(
(int) 0 => '1',
(int) 1 => '2'
),
'grant_id' => array(
(int) 0 => 56,
(int) 1 => 57
)
)
)
I want to insert the rows that every sub array goes with array key. so there will be 2 rows inserted in above case like this
insert into table (group_id. application_id, grant_id) Values (72, 1, 56);
insert into table (group_id. application_id, grant_id) Values (72, 2, 57);
howd I do that?

Answer 1

You can use Cake's Set::classicExtract() to pull out the values. I assume you know how to then save them to the DB.
http://book.cakephp.org/2.0/en/core-utility-libraries/set.html
In your case, something like (untested):
$result1 = Set::classicExtract($a, '{n}.{s}.{s}.0');
$result2 = Set::classicExtract($a, '{n}.{s}.{s}.1');
If you need the keys, you can extract those first:
$fields = Set::classicExtract($a, '{n}.{s}.{s}');

I have tried this one
$d = array(
'ApplicationsGrant' => array(
'group_id' => array(
(int) 0 => '72',
(int) 1 => '72'
),
'application_id' => array(
(int) 0 => '1',
(int) 1 => '2'
),
'grant_id' => array(
(int) 0 => 56,
(int) 1 => 57
)
)
);
for ($i=0; $i<count($d['ApplicationsGrant']['group_id']); $i++) {
echo $d['ApplicationsGrant']['group_id'][$i]."<br/>"; //outputs 72, 72
}
