i am new to array. Hope you can help me. i have 2 array. Let say:
array 1 = [[50,60],[70,80]]
array 2 = ["Fire", "Marine"]
array 1 index : Array([0]=>Array ([0]=>50 [1]=>60) [1]=>Array ([0]=>70 [1]=>80))
array 2 index : Array ([0]=> Fire [1]=>Marine)
How i can insert array 2 into array 1 like output below :
Output that i want like below:
array 3 = [["Fire",50,60],["Marine",70,80]]
array 3 index = (Array([0]=>Array ([0]=>Fire [1]=>50 [2]=>60) [1]=>Array ([0]=>Marine [1]=>70 [2]=>80))
Thanks
array_unshift() Prepend one or more elements to the beginning of an array, that you want in your child array. http://codepad.org/ufRe2qiz
$arr1 = array( array(50, 60), array(70, 80) );
$arr2 = array("Fire", "Marine");
$arr3 = array();
$i = 0;
foreach( $arr1 as $child ){
array_unshift( $child, $arr2[$i] );
$arr3[] = $child;
$i++;
}
print_r( $arr3 );
Array
(
[0] => Array
(
[0] => Fire
[1] => 50
[2] => 60
)
[1] => Array
(
[0] => Marine
[1] => 70
[2] => 80
)
)
Try this code
<?php
//original array1
$array1=array(
0=>array(0=>50,1=>60),
1=>array(0=>70,1=>80)
);
//original array2
$array2=array(0=>'Fire',1=>'Marine');
//new array
$array3=array();
foreach($array1 as $key=>$val)
{
$array3[$key]=$val;
array_push($array3[$key],$array2[$key]);
}
print_r($array3);
?>
Output : Array ( [0] => Array ( [0] => 50 [1] => 60 [2] => Fire ) [1] => Array ( [0] => 70 [1] => 80 [2] => Marine ) )
It should work give a try!!
array_push() prepend an element at the end of the array, but OP want add element on the beginning of array so you have to use array_unshift()
use array_map() function
$array1 = array(array(50,60),array(70,80));
$array2 = array("Fire", "Marine");
function mergebyindex($a, $b){
$temp = array();
$temp[] = $a;
if(is_scalar($b)){
$temp[] = $b;
} else {
foreach($b as $k => $v ){
$temp[] = $v;
}
}
return $temp;
}
echo '<pre>'; print_r(array_map('mergebyindex',$array2, $array1));
I would rethink your programming logic to be honest, juggling array's like that gets incredibly messy when you hit larger scale tasks (ESPECIALLY in mapping).
in PHP you can easily push things to the end of an array by:
$arr1[] = 'val1';
$arr1[] = 'val2';
same as:
$arr1 = array('val1','val2');
If you don't care about array positioning, you could do something like:
$arr2 = array(50,70); //original array
$arr2[] = 'marine';
would give:
$arr2 = array(50,70,'marine');
Otherwise look into PHP Array Shift, PHP Array Unshift and PHP Array Pop
