How to Compare Two or More Array Values in PHP
Using the PHP array_diff() function compares the values of two or more arrays values. And returns a new array with unique values.
Now, i will take following examples using array_diff() function in php to compare two or more array values or elements of arrays in PHP; is as follows:
- Example 1 – Compare two arrays in PHP
- Example 2 – Compare Numeric Array in PHP
- Example 3 – Compare Three Arrays in PHP
Example 1 – Compare two arrays in PHP
Let you have two arrays with duplicate values in php. And want to remove the duplicate values from these arrays and create a new unique array in PHP; so you can use the following example using array_diff() in php; is as follows:
<?php
$array_one = array("first", "second", "third", "fourth", "five");
$array_second = array("first", "second", "third", "fourth");
$res = array_diff($array_one,$array_second);
print_r($res);
?>
Example 2 – Compare Numeric Array in PHP
Let you have two numeric arrays with duplicate values. And we will remove the duplicate values from these arrays and create a new unique array in PHP: ; so you can use the following example using array_diff() in php; is as follows:
<?php
$array_one = array(1, 2, 3, 4, 5, 6);
$array_second = array(1, 2, 3, 4);
$res = array_diff($array_one,$array_second);
print_r($res);
?>
Example 3 – Compare Three Arrays in PHP
Let you have more than two arrays with duplicate values. And we will remove the duplicate values from these arrays and create a new unique array in PHP: ; so you can use the following example using array_diff() in php; is as follows:
<?php
$array1 = array('a', 'b', 'c', 'd', 'e', 'f');
$array2 = array('a', 'b', 'g', 'h');
$array3 = array('a', 'f', 'i');
$res = array_diff($array1, $array2, $array3);
print_r($res);
?>
