How can the array_column function be utilized to manipulate array structures in PHP?

The array_column function in PHP can be utilized to extract a single column from a multi-dimensional array. This can be useful for manipulating array structures by simplifying them or extracting specific data for further processing. By using array_column, you can easily access and work with specific data within arrays without having to iterate through them manually. 

// Example of using array_column to manipulate array structures
$students = [
    ['name' => 'John', 'age' => 20, 'grade' => 'A'],
    ['name' => 'Jane', 'age' => 22, 'grade' => 'B'],
    ['name' => 'Alice', 'age' => 21, 'grade' => 'A'],
];

// Extracting just the names of the students
$studentNames = array_column($students, 'name');

print_r($studentNames);
