I've a multi-dimensional array titled $result. The contents of array are as follows :
//Output of print_r($result);
Array
(
[0] => Array
(
[0] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 333
)
[1] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 332
)
[2] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 294
)
[3] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 297
)
[4] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 296
)
[5] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 298
)
)
[1] => Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] =>
[event_id] => 334
)
)
[2] => Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 336
)
)
[3] => Array
(
[0] => Array
(
[rsvp_id] => 2
[is_liked] =>
[group_name] => Student Organisation
[event_id] => 239
)
)
)
Now I'm trying to iterate over the above array in foreach loop and printing the key value as follows :
foreach ($result as $i => $key) {
print_r($key); echo "<br>";
}
die;
It prints following output :
Array
(
[0] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 333
)
[1] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 332
)
[2] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 294
)
[3] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 297
)
[4] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 296
)
[5] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 298
)
)
<br>Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] =>
[event_id] => 334
)
)
<br>Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 336
)
)
<br>Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 336
)
<br>
You can observe from the above output that the last element
Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 336
)
is repeated.
The actual final array output should be as follows :
Array
(
[0] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 333
)
[1] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 332
)
[2] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 294
)
[3] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 297
)
[4] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 296
)
[5] => Array
(
[rsvp_id] =>
[is_liked] =>
[group_name] =>
[event_id] => 298
)
)
<br>Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] =>
[event_id] => 334
)
)
<br>Array
(
[0] => Array
(
[rsvp_id] => 1
[is_liked] =>
[group_name] => CHE100
[event_id] => 336
)
)
<br>Array
(
[0] => Array
(
[rsvp_id] => 2
[is_liked] =>
[group_name] => Student Organisation
[event_id] => 239
)
)
<br>
I'm not understanding why the last element([0][event_id] => 239) is not getting accessed and the last element([event_id] => 336) gets repeated.
Can you please help me in correcting the mistake I'm making in foreach loop iteration or any other mistake I'm making.
Thanks.
