动态PHP数组结构

Question

So I want to get all of the links of the images in my database:

$findMyImages = "SELECT link FROM images WHERE model_id ='{$me['id']}'";
$imageResult = mysql_query($findMyImages) or die (mysql_error());

$result_array = array();
while($row = mysql_fetch_array($imageResult))
{
    $result_array[] = $row;
}

print_r($result_array);

The print_r(); returns this:

Array ( 
    [0] => Array (
        [0] => http://scoutsamerica.com/uploads/529746_10200706796941357_1747291081_n.jpg 
        [link] => http://scoutsamerica.com/uploads/529746_10200706796941357_1747291081_n.jpg
    )
    [1] => Array (
        [0] => http://scoutsamerica.com/uploads/64311_10200924054292655_1770658989_n.jpg 
        [link] => http://scoutsamerica.com/uploads/64311_10200924054292655_1770658989_n.jpg
    )
)

I'm looking for something similar to:

Array ( 
    [0] => http://scoutsamerica.com/uploads/529746_10200706796941357_1747291081_n.jpg 
    [1] => http://scoutsamerica.com/uploads/64311_102n_image.jpg 
    [2] => http://scoutsamerica.com/uploads/face.jpg
    [3] => http://scoutsamerica.com/uploads/another_image.jpg 
)

How can I do that?

Answer 1

Its because you are adding the result array to a new array. Simply select the information you want from the result array and place that in a new array.

For example:

while($row = mysql_fetch_array($imageResult))
{
    $result_array[] = $row[0];
}

OR:

while($row = mysql_fetch_array($imageResult))
{
    $result_array[] = $row['link'];
}

Answer 2

Attach element by element:

$result_array[] = $row[0];
// $result_array[] = $row[1]; this is the one you want to get rid of

Answer 3

Specify you just want numeric, not both:

$row = mysql_fetch_array($imageResult, MYSQL_NUM)[0];

or if you are on an older version of php:

$row = mysql_fetch_array($imageResult, MYSQL_NUM);
$row = $row[0];

The default is:

array mysql_fetch_array ( resource $result [, int $result_type = MYSQL_BOTH ] )

You see in brackets it says both, which tells it to give you both associative and numeric. You have to specify which one you want if you do not want that.
