Search for value in array of associative arrays using php

Question

How to find the array which contains moo == 'gyu'?

$arr = [
  ['moo' => 'abc', 'foo' => 1], ['moo' => 'gyu', 'foo' => 2] ...
]

I know that should be answered already but unfortunately I wasn't able to find an example.

Thank you.

@Varun.Kumar I need to find an array by pair `key=='moo' , value==$something` — Bat Man, Sep 22 '18 at 11:11
@AmiraBedhiafi That doesn't seem to be similar at all. He knows the key is `-moo`. — Barmar, Sep 22 '18 at 11:14
If you are sure about the value then you can refer this:- https://stackoverflow.com/questions/6488422/how-to-match-value-in-php-array-and-then-find-key-value — Varun.Kumar, Sep 22 '18 at 11:16

Use array_filter() to to find target array. In callback function check value of moo index.

$newArr = array_filter($arr, function($item){
    return $item['moo'] == 'gyu';
});

Also you can use array_reduce() that return target array in result.

$newArr = array_reduce($arr, function($carry, $item){
    $item['moo'] == 'gyu' ? $carry = $item : "";
    return $carry;
 });

Check result in demo

You have to used array_search() function for that.

if(array_search('gyu', array_column($arr, 'moo')) !== False) {
    echo "FOUND";
} else {
    echo "Not Found";
 }
