Purpose:

 

Array_intersect function takes two or more arrays and returns values that are same with first array.

 

Code:

 

1.    <?php

2.    $names1=array(0=>"Tahreem",1=>"Rizwan",2=>"Anwar");

3.    $names2=array(3=>"Tahreem",4=>"Rizwan",5=>"Misbah");

4.    print_r(array_intersect($names1,$names2));

5.    ?>

 

Output:

 

 

Array ( [0] => Tahreem [1] => Rizwan )

 

 

Explanation:

 

 

On line 2 and line 3 we have declared two arrays $names1, $names2 and initialize it. On line 4 we have passed both of the arrays to array_intersect function that compares both of the arrays for the same elements it prints the same elements of the array.
