Is there a way to implode the values of similar objects contained in an array? I have an array of objects:
$this->inObjs
and I'd like a comma separated string of each of their messageID properties:
$this->inObjs[$i]->messageID
Is there an elegant way to do this or am I going to have to MacGyver a solution with get_object_vars or foreachs or something similar? Thanks for the help.
$allMessageID = '';
foreach ($this->inObjs as $objectDetail) :
$allMessageID[] = $objectDetail->messageID;
endforeach;
$allMessageID_implode = implode(",", $allMessageID);
echo $allMessageID_implode;
If you can modify the class, you can implement __toString:
class MyObject {
private $messageID = 'Hello';
public function __toString() {
return $this->messageID;
}
}
// ...
$objectList = array(new MyObject, new MyObject);
echo implode(',', $objectList);
// Output: Hello,Hello
$messageIDArray;
foreach($this->inObjs as $obj){
$messageIDArray[] = $obj->messageID;
}
$string = implode(',',$messageIDArray);
$messageIDArray = [];I usually make a Helper for this situation, and use it like this
function GetProperties(array $arrOfObjects, $objectName) {
$arrProperties = array();
foreach ($arrOfObjects as $obj) {
if ($obj->$objectName) {
$arrProperties[] = $obj->$objectName;
}
}
return $arrProperties;
}
Here is a two liner:
array_walk($result, create_function('&$v', '$v = $v->property;'));
$result = implode(',', $result);
Or:
array_walk($result, function(&$v, &$k) use (&$result) { $v = $v->name; } );
$result = implode(',', $result);
Where $v->property is your object property name to implode.
Also see array_map().
, &$k and use (&$result) here? Please revisit this post. I want to use this page to close another.
