PHP compare two arrays and get the difference - php

Question

I have two arrays
$original = array(
array('fruit' => 'appel','color' => 'green'),
array('fruit' => 'Banana','color' => 'Yellow'),
array('fruit' => 'orange','color' => 'orange',)
);
and
$new = array(
array('fruit' => 'appel'),
array('fruit' => 'orange')
);
Now i want to compare the two arrays and print out the different one.
In this case i want to keep
array('fruit' => 'Banana','color' => 'Yellow')
When i use array_intersect_key
$original_new = array_intersect_key($new, $original);
it's deleting the array i want to keep.
I thought i do this:
$original_new = array_intersect_key($new, $original);
$original_new = array_diff($original_new, $original);
But this is of course not working.
Can somebody help me out whit this?

Answer 1

Using some loop and array. Check Online.
First make the array from $new array with the column only, and using the foreach loop over the $original array just check the fruit is in the $new array or not, if not than store the complete sub array in an array name $arr.
$arr = array();
$com = array_column($new, 'fruit');
foreach($original as $value){
if(!in_array($value['fruit'], $com)){
$arr[] = $value;
}
}
print_r($arr); //Array ( [0] => Array ( [fruit] => Banana [color] => Yellow ) )

Answer 2

Just to provide a different point of view,
You can get the solution using some array functions
you just need to get array_column fruit of $new array and same of $original array, get the array_diff of the 2 arrays, finally get the key ,
just try this:
$res = $original[key(array_diff(
array_column($original,'fruit'), array_column($new,'fruit')))];

Answer 3

You can do it without writing own code:
$res = array_intersect_key($original,
array_diff(array_column($original, 'fruit'),
array_column($new, 'fruit')));
demo

Answer 4

<?php
$a1=array("a"=>"red","b"=>"green","c"=>"2.00");
$a2=array("a"=>"red","b"=>"green","c"=>"2");
$r = array_diff_assoc($a1, $a2);
print_r($r);
You can use array_diff_assoc (PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)
But note that the comparison is strict (===)
The result for the code above:
Array
(
[c] => 2.00
)

Answer 5

(PHP 4 >= 4.0.1, PHP 5, PHP 7)
array_diff — Computes the difference of arrays
Compares array1 against one or more other arrays and returns the values in array1 that are not present in any of the other arrays.
$a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow");
$a2=array("e"=>"red","f"=>"green","g"=>"blue");
$result=array_diff($a1,$a2);
print_r($result);
This will return
Array ( [d] => yellow )
