counting foreach loop items - php

Question

i have the following array:
[2]=>
object(stdClass)#9 (4) {
["ID"]=>
string(32) "43c845f895a56fbe8aea9435ef8fa806"
["Type"]=>
string(8) "Campaign"
["Name"]=>
string(28) "An unmissable invitation for"
["Actions"]=>
array(5) {
[0]=>
object(stdClass)#10 (4) {
["Event"]=>
string(4) "Open"
["Date"]=>
string(19) "2013-05-07 17:00:00"
["IPAddress"]=>
string(12) "109.239.93.2"
["Detail"]=>
string(0) ""
}
[1]=>
object(stdClass)#11 (4) {
["Event"]=>
string(4) "Open"
["Date"]=>
string(19) "2013-05-07 09:01:00"
["IPAddress"]=>
string(12) "109.239.93.2"
["Detail"]=>
string(0) ""
}
[2]=>
object(stdClass)#12 (4) {
["Event"]=>
string(4) "Open"
["Date"]=>
string(19) "2013-04-30 22:29:00"
["IPAddress"]=>
string(14) "94.171.192.216"
["Detail"]=>
string(0) ""
}
[3]=>
object(stdClass)#13 (4) {
["Event"]=>
string(5) "Click"
["Date"]=>
string(19) "2013-04-30 17:43:00"
["IPAddress"]=>
string(12) "109.239.93.2"
["Detail"]=>
string(60) "http://www.rbh.co.uk/rbhevent/?name=[fullname]&email=[email]"
}
[4]=>
object(stdClass)#14 (4) {
["Event"]=>
string(4) "Open"
["Date"]=>
string(19) "2013-04-30 17:43:00"
["IPAddress"]=>
string(12) "109.239.93.2"
["Detail"]=>
string(0) ""
}
}
}
i am trying to count the events that are the same. So for example ["Event"] = Open =4 / ["Event"] = Click =1.
I am trying to achieve this via counting a foreach loop:
$i=0;
foreach($entry->Actions as $actions ) {
echo $i++;
}
Im not quite sure how to approach this? Can someone suggest a best practice?

Answer 1

$counts = array();
foreach($entry->Actions as $actions) {
if(!isset($counts[$actions->Event])) {
$counts[$actions->Event] = 0;
}
++$counts[$actions->Event];
}
print_r($counts);

Answer 2

<?php
$amounts = array(); // Events as key
foreach($entry->Actions as $actions)
{
if (isset($amounts[$actions["Event"]])) $amounts[$actions["Event"]]++;
else $amounts[$actions["Event"]] = 1;
}
print_r($amounts);
echo "<br>".$amounts["Open"];
?>
