Check array values in another array variable [duplicate] - php

Question

This question already has answers here:
Checking if ANY of an array's elements are in another array
(8 answers)
Closed 9 months ago.
I have 2 php array variables. Variables like below.
$arrIntPropertyIds = [ 1,2,3,4,5,6,7,8,9,10];
$arrIntRequestPropertyIds = [ 3, 5, 7];`
I want to check whether values of $arrIntRequestPropertyIds are in $arrIntPropertyIds without loop.
So I tried like below.
if( count(array_diff($arrIntPropertyIds,$arrIntRequestPropertyIds))==0 ) {
echo 'invalid property Id';
} else {
echo 'Valid property Id';
}
If all OR any of the value OR atleast 1 value is/are there in first array then it should show message 'invalid'.

Answer 1

All you have to do is change the order in which you present the arrays to the array_diff() function and then change the if accordingly
$arrIntPropertyIds = [ 1,2,3,4,5,6,7,8,9,10];
$arrIntRequestPropertyIds = [ 3, 5, 7];
if( count(array_diff($arrIntRequestPropertyIds, $arrIntPropertyIds))==0 ) {
echo 'Valid property Id';
} else {
echo 'invalid property Id';
}

Answer 2

Use array_diff. Simplest way to check this would be the following code
$containsValues = !array_diff($arrIntRequestPropertyIds, $arrIntPropertyIds);
Would return true or false

Answer 3

<?php
$arrIntPropertyIds = [ 1,2,3,4,5,6,7,8,9,10];
$arrIntRequestPropertyIds = [ 3, 5, 7];
$intersect = count(array_intersect($arrIntPropertyIds, $arrIntRequestPropertyIds));
if ($intersect == count($arrIntRequestPropertyIds)) {
echo '$arrIntPropertyIds include all of $arrIntRequestPropertyIds';
} elseif ($intersect > 0) {
echo '$arrIntPropertyIds include part of $arrIntRequestPropertyIds';
} else {
echo '$arrIntPropertyIds not include any of $arrIntRequestPropertyIds';
}
