check exist all value every single key in array? - php

Question

i have an $arrays array like this :
Array
(
[0] => Array
(
[0] => VUM
[1] => UA0885
)
[1] => Array
(
[0] => VUA
[1] => UA0885
)
)
i want to check if input value exist (VUA & UA0885), than not add it to this array.
Ex:
(VUA & UA0885) => not add
(VUB & UA0885) => add
(VUA & UA0886) => add
here is my code:
foreach($arrays as $array){
if($array[0] != $_REQUEST['tourcode'] || $array[1] != $_REQUEST['promocode']){
$arrays[] = array($_REQUEST['tourcode'],$_REQUEST['promocode']);
}
}
Tried use in_array too but it still add a duplicate to $arrays

Answer 1

You can iterate the array, check if the same values are found, and if not push the new values:
$tour = $_REQUEST['tourcode'];
$promo = $_REQUEST['promocode'];
$new = true; //default to true
foreach($arrays as $el){
if($el[0].'-'.$el[1] == $tour. '-' .$promo]){
$new=false;
break; //no need to continue
}
}
if($new) $arrays[]=[$tour,$promo];

Answer 2

foreach($arrays as $key => $array) {
if($array[0] == $_REQUEST['tourcode'] && $array[1] == $_REQUEST['promocode']) {
unset($arrays[$key]);
}
}

Answer 3

To check if there is an entry with tourcode AND promocode already in the array you can use something close to what you had:
function codeInArray($array, $tourcode, $promocode) {
foreach ($array as $entry) {
// check if we have an entry that has the same tour and promo code
if ($entry[0] == $tourcode && $entry[1] == $promocode) {
return true;
}
}
return false;
}
Then you can use it like this:
// run the function and see if its not in the array already
if (!codeInArray($arrays, $_GET['tourcode'], $_GET['promocode'])) {
// add the new entry to `$arrays`
$arrays[] = [
$_GET['tourcode'],
$_GET['promocode'],
];
}

Answer 4

As I understood changing your statement for !in_array might be the solution:
if (!in_array(array($_REQUEST['tourcode'],$_REQUEST['promocode']),$array))

Answer 5

<?php
$array = array(
0=>array(
0=>'VUM',
1=>'UA0885'
),
1=>array(
0=>'VUA',
1=>'UA0885'
)
);
$tour_code = trim($_REQUEST['tourcode']);
$promo_code = trim($_REQUEST['promocode']);
$filterarray = array();
$counter = 0;
foreach($array as $subarray){
foreach($subarray as $key => $value){
if(!in_array($tour_code , $subarray) || !in_array($promo_code , $subarray)){
$filterarray[$counter][] = $value;
}
}
$counter++;
}
print_r($filterarray);
?>
