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. There are other options as well. Check out the article to see more. Relevant Content - PHP Associative Arrays…

How to Iterate JSON Arrays in PHP Using a Recursive Function with GeoJSON Load and set your GeoJSON content into a PHP variable Use json_decode to convert the JSON content into a php multidimensional array Create a custom recursive function to iterate the JSON content Run a while loop inside the custom function and call itself when it has children Run a foreach loop on your root array from your geojson content Create a new RecursiveArrayIterator class inside the loop Call your custom recursive function and pass in your RecursiveArrayIterator class Continue working and processing your GeoJSON array PHP Code Example: Loop Through a Multidimensional JSON Array using recursion and a foreach loop with GeoJSON //Fetches the GeoJSON array. $geojson = file_get_contents("sampleGeoJSON.json",false); //Converts GeoJSON into an associative array. $geojson_array = json_decode($geojson,true); //A recursive function to traverse the GeoJSON array. function traverseGeoJSON($iterator) { //If there is a property left. while (…
