Php comparing muliple values in multidimensional arrays with another multidimensional array

Question

I have a multidimensional array

Simple example array

[0]=>array(2) {
["slug"]=>string(12) "exampleslug1"
["tax"]=>string(11) "exampletax1"}
[1]=>array(2) {
["slug"]=>string(12) "exampleslug2"
["tax"]=>string(11) "exampletax2"}
[2]=>array(2) {
["slug"]=>string(12) "exampleslug2"
["tax"]=>string(11) "exampletax3"}

Now i want to check another multidimensional array for both values.

So for example. I want to check if the slug is "exampleslug2" and the tax = "exampletax2" So in this case it should return false/true/false.

Ive tried in_array but i can't seem to get that to work for multidimensional. Can anyone help me out with a solution for checking multiple values in the multidimensional array to be the same as in a second multidimensional array.

If it try something like

if (!in_array($termSlug, $externalTermSlugs['slug']) && !in_array($termTax, $externalTermSlugs['tax']) ) {}

It adds everything multiple times, what i want to have is that it adds everything once unique and doesn't overwrite if it already exists.

How about in_array([ "slug" => $termSlug, "tax" => $termTax ], $externalTermSlugs)? Also array_unique($externalTermSlugs, SORT_REGULAR) will deduplicate without any checks needed — apokryfos

try this code

<?php
$arr = array( 0 => array("slug"=>"exampleslug1","tax"=>"exampletax1"),
             1 => array("slug"=>"exampleslug2","tax"=>"exampletax2"),
             2 => array("slug"=>"exampleslug2","tax"=>"exampletax3"));
foreach($arr as $key => $value){
    if($value['slug']=="exampleslug2" && $value['tax']=="exampletax2"){
        echo "true"."<br>";
    }else{
        echo "false"."<br>";
    }
}
?>

Thnx i ended up using something like your code. I'm doing a foreach to set the value if it exists, en then underneath if the value is not set to run my script ( i needed it to happen if the code didn't exist yet)

foreach($arr as $key => $value) {             if ($value === ['slug' => $termSlug, 'tax' => $termTax]) {                 $alreadySet = true;                 continue;             }         }
