I have two arrays:
array(1,2,3,4,5)
array(10,9,8,7,6)
Final array Needed:
array(0=>1:10,1=>2:9,2=>3:8,3=>4:7,4=>5:6)
I can write a custom function which would be quieck enough!! But i wanted to use a existing one so Is there already any function that does this in php? Pass the two input arrays and get the final array result? I read through the array functions but couldn't find any or combination of function that would provide me the result
No built in function but really there is nothing wrong with loop .. Just keep it simple
$c = array();
for($i = 0; $i < count($a); $i ++) {
$c[] = sprintf("%d:%d", $a[$i], $b[$i]);
}
or use array_map
$c = array_map(function ($a,$b) {
return sprintf("%d:%d", $a,$b);
}, $a, $b);
Try this :
$arr1 = array(1,2,3,4,5);
$arr2 = array(10,9,8,7,6);
$res = array_map(null,$arr1,$arr2);
$result = array_map('implode', array_fill(0, count($res), ':'), $res);
echo "<pre>";
print_r($result);
output:
Array
(
[0] => 1:10
[1] => 2:9
[2] => 3:8
[3] => 4:7
[4] => 5:6
)
array_fill ... implode would do just fineAnd especially: https://www.php.net/manual/en/function.array-combine.php
Also, I don't quite understand the final array result? Do you mean this:
array (1 = 10, 2 = 9, 3 = 8, 4 = 7, 5 = 6)
Because in that case you'll have to write a custom function which loops through the both arrays and combine item[x] from array 1 with item[x] from array 2.
<?php
$arr1=array(1,2,3,4,5);
$arr2=array(10,9,8,7,6);
for($i=0;$i<count($arr1);$i++){
$newarr[]=$arr1[$i].":".$arr2[$i];
}
print_r($newarr);
?>
Use array_combine
array_combine($array1, $array2)
1:10or1,10?
