Original way of writing, returning a certain column or several columns of the array

The code just released in the latest version of php can save a lot of work, and you don’t have to go to foreach

//Get record data
//This is the latest array function of PHP
$records = array(
 array(
 'id' => 0,
 'pre' => ; 2,
 'next' => 6,
 ),
 array(
 'id' => 1,
 'pre' => 13,
 'next' => 18,
 ),
 array (
 'id' => 3,
 'pre' => 3,
 'next' => 8,
 ),
 array(
 'id' => 4,
 'pre' => 0,
 'next' => 5,
 )
);

$all_pre = array_column($records, 'pre');
//Print out all predecessor nodes
print_r($all_pre);
?> ;
