Question

I have a simple PHP function that will grab information from a database based on a unique ID:

function oracleGetGata($query, $id="id") {
    global $conn;

    $results = array();
    $sql = OCI_Parse($conn, $query);
    OCI_Execute($sql);
    while ( false!==($row=oci_fetch_assoc($sql)) ) {
        $results[ $row[$id] ] = $row;
    }
    return $results;
}

So for example $array = oracleGetData('select * from table') would return:

[1] => Array
(
    [Title] => Title 1
    [Description] => Description 1
)
[2] => Array
(
    [Title] => Title 2
    [Description] => Description 2
)

This is fine, however, if I just want to return one record $array = oracleGetData('select * from table where id = 1') it returns the data like:

[] => Array
(
    [Title] => Title 1
    [Description] => Description 1
)

Not only am I unsure of how to reference this (there is nothing identifying the array) I’d also like to somehow change my function so if it just returns one record, it will just be a simple one dimensional array.

I’ve looked into the usual PHP array functions but can’t find anything that’ll help, nor an easy way of identifying how deep the array is.

Would really appreciate any help, thank you

Use array_pop():

$array = array_pop(oracleGetData('select * from table where id = 1'));

You will then get one single array:

Array
(
    [Title] => Title 1
    [Description] => Description 1
)

Instead of an array embedded in another one:

Array
(
    [] => Array
    (
        [Title] => Title 1
        [Description] => Description 1
    )
}
