Re: [PHP] Newbie: Array of objects iteration
I think you are just looking for the key in the wrong place. Try:
foreach ( $records as $record ) {
foreach( $record as $column=$value ) {
echo $column is $value\n;
}
}
You've got the columns names in each record, not in the global recorset.
Good luck ;-)

Asunto: [PHP] Newbie: Array of objects iteration
Hello all,
I'm grabbing all records from a table using:
$records = $stmt-fetchAll(PDO::FETCH_OBJ);
return $records;
In order to display the values we can do:
foreach ($records as $record)
{
echo $record-id;
echo $record-name;
}
However, I'd like to grab, also, the *column names*.
I've tried:
foreach ($records as $column=$value)
{
echo $column is $value\n;
}
But I get:
Catchable fatal error: Object of class stdClass could not be converted to
string
Can I have your help on how can I properly get the column values?
Regards,
Márcio

print_r($record); often helps - you can see what is actually returned
and check that you have names rather than numbers for the fields ;)
print_r($records); becomes a little large if you have a lot of results
so use with care :)

RE: [PHP] Newbie: Array of objects iteration
@LinuxManMikeC and all @All
Thanks. I was more or less aware of that possibility, however, please let me
share the big picture will you guys:
The main point is to access the properties name as well as values, of that
object, and put them on a xls file.
Instead of using mysql_num_rows, and mysql_num_files, and split and use a
bunch of loops I thought:
Maybe fetching as an object may help me doing this far better.
However, I'm having a hard time figuring out how to make the switch.
To be honest, I don't really know if iterate is the buzz word here, I
would like to understand a little bit more the following:
We have in our hands an Object returned by a Fetch_All w/ fetch_obj option
applied to it, that object, when I do var_dump, reveals himself as in
object, containing an array and, each key of that array corresponds the
column names of our table or tables we have previously fetched.
However, since we are working with an object, should we think differently
than if we were working with an array? If so, it is, in the fact, iteration,
the best option we have to put all properties and values into a xls file? Or
there are far better options for that?
@Lester
Yes, actually, I was having only one record on the database, but I believe
that is far to less. Since I was not been able to see if I was getting one
object, or several objects. That make me think of that. Thanks :) And
because of that, I was able (I hope) to properly understand Fernando
example:
@Fernando
foreach ( $records as $record ) {
foreach( $record as $column=$value ) {
echo $column is $value\n;
}
}
So the first foreach will iterate over each object of stdClass that
corresponds to each record of mysql data fetched, then, for each of them,
take the associative array key and the corresponding value...
Correct? :DDD
However, is this the right track to archive the goal stated above, or, they
are far better ways for doing so?
Regards,
Márcio

Correct about my example, although I'm not sure if you get each record as an
array or as an object. Anyway, you can iterate both.
And if you want to get the column names, I suppose you could use array_keys()
on the first record if you receive an array, or maybe get_object_vars() if it's
an objecs (note that with this you get an array with keys and values).
I've found PDOStatement-getColumnMeta(). There's a big fat warning saying this
is experimental, but you could take a look in case you need more data on the
columns.
Hope it helps.

Right now, I have something like this:
foreach ($objRecord as $record)
{
//we will have a new line.
$xls_file .=\n;
foreach ($record as $column=$value)
{
$xls_file .= $value.\t;
}
}
The only thing I need now, is to put on top, the column names, and I have
myself a xls file. YUpii!!
I just need the column names... I will take a look on those functions you
have mentioned.
Thanks a lot, :)

Update:
PDO::FETCH_OBJ
Returns an anonymous object with property names that correspond to the
column names returned in your result set.
I will give a shot on array_keys however, is there any method to access the
PROPERTIES NAMES of a given object?

Dear all, it's done. Can I call your help for the remain issues please, I'm sure they are easy to explain, and at some extend, common: http://pastebin.com/m691d3e66 Instead of saving to the database, if I do a print_r or a var_dump, I get the charsets quite ok. However, they do not appear properly in the xls file. I've tried to use utf8_encode but I was not sure where to apply it, and I end up with the same strange chars on the .xls file. If I write a meta tag containing charset information on the script that generates the file, I get headers already send message. I've tried to add Content-type: application/x-msdownload; *charset=UTF-8;* but no success either... Would a proper use of utf8_encode solve this? If so, where?
