php check value exist in multi array code example

Example 1: php check if any of multiple values in array

function in_array_any($needles, $haystack) {
   return !empty(array_intersect($needles, $haystack));
}

echo in_array_any( [3,9], [5,8,3,1,2] ); // true, since 3 is present
echo in_array_any( [4,9], [5,8,3,1,2] ); // false, neither 4 nor 9 is present

Example 2: php check if value exists in multidimensional array

// 1d array
in_array('something', $array);

// 2d array
array_column($multi_array, 'your_column');

/**
0 => ['hi'=>0, 'your_column'=>1, 'hi'=>0, 'your_column'=>3]
will be
[1, 3]
and then you can apply the in_array function on that new array ^
