How Can I Efficiently Build Laravel Eloquent Queries with Multiple WHERE Clauses?

Building Queries with Multiple WHERE Clauses Using Laravel Eloquent

Consider the following scenario: you're utilizing Laravel's Eloquent query builder and need to create a query with multiple WHERE clauses targeting different conditions. While it's possible to do so with multiple where method calls, this approach can become repetitive and unwieldy.

To address this, Laravel provides several alternative options for constructing such queries more elegantly.

Using an Array of Conditions in where

As of Laravel 5.3, you can specify multiple conditions in an array passed to the where method:

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    // ...
]);

Using an Array in where

Before Laravel 5.3, you could also use an array to specify conditions in where:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];
$results = User::where($matchThese)->get();

Using orWhere

Alternatively, you can group conditions using orWhere:

$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

Resulting SQL Query

Using the orWhere method will generate a query similar to this:

SELECT * FROM users
WHERE (field = value AND another_field = another_value AND ...)
OR (yet_another_field = yet_another_value AND ...)

These techniques enable you to build queries with multiple WHERE clauses in a more concise and maintainable manner.
