PhP MultiDimensional Array fetching - php

Question

I am not really familiar on how php handles array, in .NET I can access array using this method
array[x][y];
My question is:
I am retrieving records from the database and returning it to the $res_merchant_field
$res_merchant_field = $this->CI->merchantfield_model->merchantfield_list( $str_where );
and $res_merchant_field will be populated with this record:
Array
(
[0] => stdClass Object
(
[MFID] => 1
[MFName] => Bill No
[FTID] => 1
[DTID] => 1
[MFRequired] => 1
[MFDefaultValue] =>
[MFDueDate] => 0
[MFToBePaid] => 0
[MFMaxLength] => 12
[MFOrderNo] => 1
[MFStatus] => 1
)
[1] => stdClass Object
(
[MFID] => 2
[MFName] => Gallons Consumed
[FTID] => 1
[DTID] => 2
[MFRequired] => 1
[MFDefaultValue] =>
[MFDueDate] => 0
[MFToBePaid] => 0
[MFMaxLength] => 5
[MFOrderNo] => 2
[MFStatus] => 1
)
[2] => stdClass Object
(
[MFID] => 3
[MFName] => Amount Due
[FTID] => 3
[DTID] => 1
[MFRequired] => 1
[MFDefaultValue] =>
[MFDueDate] => 0
[MFToBePaid] => 1
[MFMaxLength] => 15
[MFOrderNo] => 3
[MFStatus] => 1
)
)
How can I access and fetch the record from that array with this condition:
it will look through all the array find specific index, lets say index 0 which is MFID,
after getting the MFID and comparing it with another variable, if it is true,
it will get the DTID for that array MFID.
example:
get MFID = 1, the DTID will be 1, if I get the MFID = 3, the DTID will be 1.
or how can I access the array like $array[x][y]?
Thanks in advance.

Answer 1

The problem is that the second level is not an array but instead an object, to access a property you will have to use this format.
$array[$x]->$y;
Unfortunately you cannot access a property by an index do o get the MFID of the 0th Item you will need to say
$array[0]->MFID;
