I want to user two array value at the same time like arr1[0] and arr2[0] value at the same time length of these array is same in php

php compare two arrays for matches
php merge array values with same keys
php compare two array keys and values
php array_intersect multidimensional
php compare two arrays for not matches
php compare two arrays for equality
php array same key different value
$Arr1 = [343,353,353,646,757,8];

$Arr2 = [35,353,646,75,23,23];

I Want to loop through these array and get data like $Arr1[0] And $Arr2[0], and then $Arr1[1] and $Arr2[1].... like that how can i do that using php

You can approach this by using array_map

$a = array_map(null, $array1, $array2)


array_map(function($v1, $v2){echo $v1.'---'.$v2."\n";}, $Arr1, $Arr2);

Working example : https://3v4l.org/J6elq

array_diff - Manual, Of course you can check deeper dimensions by using array_diff($array1[0], $​array2[0]);. If you just need to know if two arrays' values are exactly the same (​regardless of but working with two arrays and modifying them at time, not returning an array as function my_array_diff($arr1, $arr2) { for ($i = 0; $i < $​size; $i++) Questions: I have these two arrays: one is filled with information from an ajax request and another stores the buttons the user clicks on. I use this code (I filled with sample numbers): var array1 = [2, 4]; var array2 = [4, 2]; //It cames from the user button clicks, so it might be disordered.

You could use a for loop:

for ($i = 0; $i < count($Arr1); $i++) {
    echo "{$i}: {$Arr1[$i]} {$Arr2[$i]}\n";

array_intersect - Manual, array_intersect() returns an array containing all the values of array1 that are Note: Two elements are considered equal if and only if (string) $elem1 yields the following: array(3) { [0]=> int(2) [1]=> int(4) [2]=> int(6) } array(3) { want to use this function with arrays which have sometimes the same value array (size​=3) 0  Given two arrays: arr1[0..m-1] and arr2[0..n-1]. Find whether arr2[] is a subset of arr1[] or not. Both the arrays are not in sorted order. It may be assumed that elements in both array are distinct.

Use a for loop or a foreach with index/key.


$count = max(count($arr1), count($arr2));
for($i = 0; $i < $count; $i++){
     echo $arr1[$i];
     echo $arr2[$i];


 foreach($arr1 as $key => $val){
     echo $val;
     echo $arr2[$key];

array_combine - Manual, Creates an array by using the values from the keys array as keys and the values from 5.4.0, Previous versions issued E_WARNING and returned FALSE for empty arrays. But if you need to keep all values, you can use the function below: Add empty strings to ensure arrays $a and $b have same number of elements i'm having two arrays of booleans: arr1 = [true, false, false, true] arr2 = [false, false, false ,true] I want to make a function that is returning true only if arr1 and arr2 contains true but only one true for each array. For example for the above arrays the function must return false. If the arrays are like this:

Check if two arrays are equal or not, Given two given arrays of equal length, the task is to find if given arrays are equal or not. Two arrays are said to be equal if both of them contain same set of elements, Input : arr1[] = {1, 2, 5, 4, 0}; arr2[] = {2, 4, 5, 0, 1}; Output : Yes Input : arr1[] arr2[] and check if count of every element in arr2[] matches with count in arr1[]. If you want to use this function with arrays which have sometimes the same value several times, it won't be checked if they're existing in the second array as much as in the first. So I delete the value in the second array, if it's found there:

Merge two sorted arrays, Given two sorted arrays, the task is to merge them in a sorted manner. arr2[] and one by one insert elements (like insertion sort) of arr3[] to arr1[]. This Method 2 (O(n1 + n2) Time and O(n1 + n2) Extra Space) Merge arr1[0..n1-1] and arr2[0..n2-1] into Otherwise do same with second array Inserting values to a map. Method 4 Efficient Approach(Hashing): Create a hash table where (key, value) tuples are represented as (sum, frequency) tuples. Here the sum are obtained from the pairs of 1st and 2nd array and their frequency count is maintained in the hash table.

How to merge 2 arrays alternatively..? - PHP, I want to generate arra3 which contains time followed by the value… Assuming that both arrays have the same length: I just make on esimple example: $arr1 = array(1, 3, 5); $arr2 = array(2, 4, 6); $new = array(); for ($i=0; $i<count($arr1); $i​++) Lose the for loop as it has no point, and change these lines If array arr1 initially contains the elements 0, 6, 0, 4, 0, 0, 2 in this order, what will arr2 contain refer execution of the code segment? (A) 6, 4, 2 (B) 0, 0, 0, 0, 6, 4, 2
