how to retrive all object array with one value? - php

Question

This question is a follow up from this Now for my follow up question I also have this object on page:
Array
(
[registrants] => Array
(
[0] => Registrant Object
(
[title] => D C
[link] => **********
[id] => ***************
[updated] => 2013-03-06T12:11:49-05:00
[lastName] => C
[firstName] => D
[email] => *********
[personalInformation] => PersonalInformation Object
(
[cellPhone] =>
[label] =>
[addr1] =>
[addr2] =>
[addr3] =>
[city] =>
[state] =>
[postalCode] =>
[province] =>
[country] =>
[phone] =>
)
[businessInformation] => BusinessInformation Object
(
[fax] =>
[website] =>
[blog] =>
[company] =>
[jobTitle] =>
[department] =>
[label] =>
[addr1] =>
[addr2] =>
[addr3] =>
[city] =>
[state] =>
[postalCode] =>
[province] =>
[country] =>
[phone] =>
)
[customInformation1] => Array
(
)
[customInformation2] => Array
(
)
[registrationStatus] => REGISTERED
[registrationDate] => 2013-03-06T12:11:49-05:00
[guestCount] => 0
[paymentStatus] => NA
[orderAmount] =>
[currencyType] =>
[paymentType] =>
[costs] => Array
(
)
)
[1] => Registrant Object
(
[title] => Test Test
[link] => ****
[id] => *************
[updated] => 2013-03-06T12:47:47-05:00
[lastName] => Test
[firstName] => Test
[email] => ***************
[personalInformation] => PersonalInformation Object
(
[cellPhone] =>
[label] =>
[addr1] =>
[addr2] =>
[addr3] =>
[city] =>
[state] =>
[postalCode] =>
[province] =>
[country] =>
[phone] =>
)
[businessInformation] => BusinessInformation Object
(
[fax] =>
[website] =>
[blog] =>
[company] =>
[jobTitle] =>
[department] =>
[label] =>
[addr1] =>
[addr2] =>
[addr3] =>
[city] =>
[state] =>
[postalCode] =>
[province] =>
[country] =>
[phone] =>
)
[customInformation1] => Array
(
)
[customInformation2] => Array
(
)
[registrationStatus] => REGISTERED
[registrationDate] => 2013-03-06T12:47:47-05:00
[guestCount] => 0
[paymentStatus] => NA
[orderAmount] =>
[currencyType] =>
[paymentType] =>
[costs] => Array
(
)
)
)
[nextLink] =>
)
So following the same theory I am retriving the values like this:
<?php echo $Registrant->lastName; echo $Registrant->firstName; echo $Registrant->email; ?>
but this only retrieves the first lastname and firstname from [0] => Registrant Object not from 1 => Registrant Object how to i get all of the first names and last names?
Thank everyone for there interest and there time.
Kind regards
Chris

Answer 1

To explain your scenario a bit further than other answers.
You have an array of (Registrant) objects here. This is actually an associative array (as all PHP arrays) with indices from 0 - 1.
$registrantObjects[0] // would give first Registrant object
$registrantObjects[1] // would give second Registrant object
You can access them both. But if you want to iterate the array (i.e. going over all elements and do the same for each one), you should use a loop.
PHP has a nice foreach loop for this use case:
foreach ($registrantObjects as $registrant) {
// $registrant is a Registrant object here
echo $registrant->lastName;
}
You could also try this:
foreach ($registrantObjects as $index => $registrant) {
// $registrant is a also Registrant object here
// But we have a variable $index, too. It represents the current 'key'
// We have a normal (numbered) array thus the keys are [0..1]
echo $registrant->lastName;
}
And both loops are equal to this for loop:
for ($i = 0, $len = count($registrantObjects); $i < $len; $i++) {
// $registrantObjects[$i] gives a Registrant object
}

Answer 2

Lets say the object you printed is "$RegistrantObjects"
You can do the following thing :
foreach ($RegistrantObjects as $registrant)
{
echo $registrant->lastName;
}
Within the foreach, the $registrant object will be accessible the same way that you code accesses it.

Answer 3

Try the below code;
<?php
foreach($Registrant as $reg) {
echo $reg->firstname;
echo $reg->lastname;
}
?>
