Difference Between arra_merge and array_combine | Learning Curve- Perfect Tutorial for the beginers

Example: array_merge

<?php
//Example of array_merge


$firstarray=array("vasanthan"=>"software engineer","nazar"=>"Team Lead");
$secondarray=array("vasanthan"=>"Web Designer","Sreejith"=>"Project Manager");
$merge_result=array_merge($firstarray,$secondarray);
print_r($merge_result);

//Ouput will be like as below

/*Array
(
    [vasanthan] => Web Designer
    [nazar] => Team Lead
    [Sreejith] => Project Manager
)*/



?>

<?php

//Example of array_merge

$firstarray=array("vasanthan"=>"software engineer","nazar"=>"Team Lead");

$secondarray=array("vasanthan"=>"Web Designer","Sreejith"=>"Project Manager");

$merge_result=array_merge($firstarray,$secondarray);

print_r($merge_result);

//Ouput will be like as below

/*Array

(

[vasanthan] => Web Designer

[nazar] => Team Lead

[Sreejith] => Project Manager

)*/

here i used the same key for the both arrays. in firstarray i used “vasanthan” as key second array again used “vasanthan” as key. in output second array key is override the first array key.

Example array_combine

<?php
//Example of array_combine


$firstarray=array("vasanthan","nazar");
$secondarray=array("Software engineer","Project Manager");
$merge_result=array_combine($firstarray,$secondarray);
print_r($merge_result);

//Ouput will be like as below

/*
Array
(
    [vasanthan] => Software engineer
    [nazar] => Project Manager
)
*/

?>

<?php

//Example of array_combine

$firstarray=array("vasanthan","nazar");

$secondarray=array("Software engineer","Project Manager");

$merge_result=array_combine($firstarray,$secondarray);

print_r($merge_result);

//Ouput will be like as below

Array

(

[vasanthan] => Software engineer

[nazar] => Project Manager

)

In array_combine first array values as key and the second array values as value in the result array.
