Customized Merge Array Function

[Rockey Killer]

Hey friends today while I was coding i found a issue with merge array function

PHP Code:

array_merge($array1,$array2); 


This is the function you can read the further documentation here

http://php.net/manual/en/language.types.array.php

Now While I was coding , here is my code

PHP Code:

$array1 = array(
    '1' => 'one',
    '2' => 'two',
    '3' => 'three',
    '4' => 'four'
    );
$array2 = array();
foreach($array1 as $key => $v) {
    $array2[$v] =  $key;
    };
$newarray  = array_merge($array1,$array2);
foreach($newarray as $key => $v) {
    echo $key."    ".$v."\n";
    }; 


Result that I got was

Code:

0    one
1    two
2    three
3    four
one    1
two    2
three    3
four    4

Now you can see the index and key have changed and now 0[/code] is written in-front of one , obviously I wasn't expecting that but i can hardly find any solution for this . So I decided to write my own function for merging two arrays.

PHP Code:

function mergearray($array1,$array2) {
    $array3 = array();    
    foreach($array1 as $key => $v) {
        $array3[$key] =  $v;
    };
    foreach($array2 as $key => $v) {
        $array3[$key] =  $v;
    };
    return $array3;
    }; 


You can use that function to merge two arrays now you can see my full code here

PHP Code:

$array1 = array(
    '1' => 'one',
    '2' => 'two',
    '3' => 'three',
    '4' => 'four'
    );
$array2 = array();
foreach($array1 as $key => $v) {
    $array2[$v] =  $key;
    };
$newarray = mergearray($array1,$array2);
foreach($newarray as $key => $v) {
    echo $key."    ".$v."\n";
    };

function mergearray($array1,$array2) {
    $array3 = array();    
    foreach($array1 as $key => $v) {
        $array3[$key] =  $v;
    };
    foreach($array2 as $key => $v) {
        $array3[$key] =  $v;
    };
    return $array3;
    }; 


and this one works perfectly . Here is the output

[code]
1 one
2 two
3 three
4 four
one 1
two 2
three 3
four 4
[code]

Now you can see that output has corrected

No one ever promised me that the path I have chosen will be easy and no one ever promise me to accompany me . So i have to figure out the solutions of my own and the day I will quit will be the day when I will die.
