I have a two arrays and need to get one from them. array_merge, array_map etc. Doesn't give right result.
$array1 = [1,2,3,4,5];
$array2 = [a,b,c,d,e];
I need $array3 = [[1,a], [2,b], [3,c]]...
What is the best way to get that result?
using array_map(null, $arr1, $arr2) you can achieve the result.
http://php.net/manual/en/function.array-map.php
php > $q = array_map(null, $array1, $array2);
php > print_r($q);
Array
(
[0] => Array
(
[0] => 1
[1] => a
)
[1] => Array
(
[0] => 2
[1] => b
)
[2] => Array
(
[0] => 3
[1] => c
)
[3] => Array
(
[0] => 4
[1] => d
)
[4] => Array
(
[0] => 5
[1] => e
)
)
The for loop approach is the following:
<?php
$array1 = [1,2,3,4,5];
$array2 = ['a','b','c','d','e'];
$array3 = array();
if(count($array1) == count($array2))
{
for($i = 0; $i < count($array1); $i++)
{
$array3[] = [$array1[$i],$array2[$i]];
}
}
else
{
die("SIZE MISMATCH");
}
echo '<pre>';
print_r($array3);
And the output is:
Array
(
[0] => Array
(
[0] => 1
[1] => a
)
[1] => Array
(
[0] => 2
[1] => b
)
[2] => Array
(
[0] => 3
[1] => c
)
[3] => Array
(
[0] => 4
[1] => d
)
[4] => Array
(
[0] => 5
[1] => e
)
)
