In what situations would it be more efficient to handle data filtering in PHP rather than using SQL queries?

In situations where the data filtering requirements are complex and involve multiple conditions or calculations, it may be more efficient to handle the filtering in PHP rather than using SQL queries. This can reduce the complexity of SQL queries and improve performance by offloading some of the processing to the PHP application. 

// Example of filtering data in PHP rather than using SQL queries

// Assume we have an array of data that needs to be filtered
$data = [
    ['id' => 1, 'name' => 'John', 'age' => 25],
    ['id' => 2, 'name' => 'Jane', 'age' => 30],
    ['id' => 3, 'name' => 'Alice', 'age' => 22],
];

// Filter the data based on a condition (e.g. age greater than 25)
$filteredData = array_filter($data, function($item) {
    return $item['age'] > 25;
});

// Output the filtered data
print_r($filteredData);
