I have an array that looks like this:
Array
(
[0] => stdClass Object
(
[user_id] => 10
[date_modified] => 2010-07-25 01:51:48
)
[1] => stdClass Object
(
[user_id] => 16
[date_modified] => 2010-07-26 14:37:24
)
[2] => stdClass Object
(
[user_id] => 27
[date_modified] => 2010-07-26 16:49:17
)
[3] => stdClass Object
(
[user_id] => 79
[date_modified] => 2010-08-08 18:53:20
)
)
and what I need to do is print out the user id's comma seperated so:
10, 16, 27, 79
I'm guessing it'd be in a for loop but i'm looking for the most efficient way to do it in PHP
Oh and the Array name is: $mArray
I've tried this:
foreach($mArray as $k => $cur)
{
echo $cur['user_id'];
echo ',';
}
which others have suggested.
However I keep getting this error:
Fatal error: Cannot use object of type stdClass as array in.
I think it's because this array is not a typical array so it requires some different syntax?
Each array element is a (anonymous) object and user_id
is a property. Use the object property access syntax (->
) to access it:
foreach($mArray as $k => $cur)
{
echo $cur->user_id;
echo ',';
}
foreach ($mArray as $cur){
echo $cur->user_id;
}
you can do it this way since you are working with objects
Use this if you want to avoid the trailing comma (,
).
$ids = array();
foreach ($array as $obj){
$ids[] = $obj->user_id;
}
echo join(', ', $ids);
Pretty close...
foreach($mArrray as $k => $cur)
{
echo $cur->user_id.', ';
}
