In this article we will show you the solution of PHP remove element from array by value, in PHP, array_search () and unset () can be used to remove an element by value from an array.

In the array_search () function, a given value is searched for and the array's first matching key is returned if it exists in the array, or false otherwise.

// Use the unset () function to delete
// elements

// Display the array element
print_r($arr);
?>
