How to extract a column from an array in PHP?
To extract a column from an array in PHP, we can use the array_column function.
For instance, we write
$samples = array(
array('page' => 'page1', 'name' => 'pagename1'),
array('page' => 'page2', 'name' => 'pagename2'),
array('page' => 'page3', 'name' => 'pagename3')
);
$names = array_column($samples, 'name');
to create the $samples array.
And then we call array_column with $samples and 'name' to return an array with the values with the 'name' key in each array.
