How to get an array of specific "key" in multidimensional array without looping [duplicate]
(4 answers)
Closed 8 years ago.
In PHP, is there any built-in array function that I could use to change an array...
From:
Array (
[0] => Array
(
[item_id] => 1
)
[1] => Array
(
[item_id] => 3
)
[2] => Array
(
[item_id] => 2
)
)
To:
Array
(
[item_id] => Array ( [0] => 1, [1] => 2, [2] => 3 )
)
Thanks for your help.
Even if you cant find a built-in function, you can write a small loop. Although im sure this can also be done with array_map
foreach($yourArray as $subArray)
{
$newArray["item_id"][]=$subArray["item_id"];
}

[started] => 1

)
[2] => Array
(
[0] => 96500
[1] => 96503
[2] => 96506
[3] => 96509
[4] => 96512
[5] => 96515
)
[3] => Array
(
[0] => 96501
[1] => 96504
[2] => 96507
[3] => 96510
[4] => 96513
)

[3] => 96511
[4] => 96514
)
)
[name] => Test
[name_or_email] =>
[submitbtn] => 1
)
assuming your variable is $studentsResult (which contains the whole array you have posted)
in that case:
foreach($studentsResult['studentid'] as $studentId => $studentValues){
$tempStudents[$studentId] = join(',',$studentValues);
}
and then $tempStudents is what you're probably looking for\
If, however all those IDs needs to be under that ONE student, then you haven't said where is the ID, but you can follow the answer on flattening the array in one of the comments or do:
$tempStudents = [];
foreach($studentsResult['studentid'] as $someId => $studentValues){
$tempStudents = array_merge($tempStudents,$studentValues);
}
echo join(',',$tempStudents);

Try this.
$object = json_decode(json_encode($array));
or you can also do this.
$object = (object) $array;
Here's a demo.

PHP reindex array? [duplicate]

How do you reindex an array in PHP but with indexes starting from 1?

I need to display array in sequence
my array
Array
(
[0] => test#yahoo.com
[1] => rans#yahoo.com
[2] => maria#gmail.com
[3] => lspap#gmail.com
[6] => sage#yahoo.com
[7] => rlope#hotmail.com
[13] => alyssa#gmail.com
)
I want output like following
Array
(
[0] => test#yahoo.com
[1] => rans#yahoo.com
[2] => maria#gmail.com
[3] => lspap#gmail.com
[4] => sage#yahoo.com
[5] => rlope#hotmail.com
[6] => alyssa#gmail.com
)
Now my question is how can display array like above sequence in PHP?
use array_values to reindex an array
$array = array_values($array);
To display the values in sequence use a foreach loop as so
foreach($array as $arr){
echo $arr."\n";
}
to store the values with new indexes or keys use
array_values($array);
