php get variable names from an array/object


I have some output from a mysql  database query and when I do a print_r I get something like this:

    [0] => stdClass Object
            [order_date] => 2015-03-17
            [name] => some name
            [branch] => Some branch
            [total] => 11.40

    [1] => stdClass Object
            [order_date] => 2015-03-17
            [name] => Some other name
            [branch] => Some other branch
            [total] => 31.20

    [2] => stdClass Object
            [order_date] => 2015-03-12
            [name] => Last one
            [branch] => Last branch
            [total] => 37.20

what i want to do is get the names of the fields (order_date,name,branch,total)
how can i get them through code?

just so that I can use the names as headers...

You have an array of objects, so you'll need to loop through the array to access each object, and then get the properties of the object. Assume your array is called $data:

foreach ($data as $record):
    echo $record->order_date;
    echo $record->name;
    echo $record->branch;
    echo $record->total;

hi, sorry if i confused anyone...

i know how to get the data, it's the field names I want to access, in order to auto generate a table with them as headings...

like this.... kind of

| order_date | branch | name | total
| 01-01-2015 | some | some | 100

Sorry - just realised I mis-read what you needed. To get the actual property names you can use the get_object_vars():

Again, assuming your array is called $data:

$fieldNames = get_object_vars($data[0]);

Open in new window

You will then have an array of fields, and you can loop them like so:

foreach ($fieldNames as $field => $value):
    echo $field;
