How to Filter PHP Associative Arrays with Code Examples in 2023
How to Filter PHP Associative Array Code Example You will want to use the array_filter function on a PHP associative array to filter correctly. Many times, your array may also be multi-dimensional. We recommend creating a unique array filter function using a recursive pattern. Here's a sample code snippet from the article. // Option 1: Using a array_filter function function filterStudentsBySemesterOne($students_data) { return array_filter($students_data, function($v) { return $v["Semester"] > 5; }); } // Option 2: Filter associative arrays using an iterative approach (not recommended) function filterStudentsBySemester($data, $semester) { // Do some logic to determine whether we can return true. $filtered_arr = []; foreach($data as $k => $v) { if( $v["Semester"] > $semester ) { $filtered_arr[$k] = $v; } } return $filtered_arr; } This code is an example of an iterative approach.
