如何使用PHP从多个值等于x的数组中选择数据？

Question

How can I use PHP, to select all membership plans where 'type_id' = x and level_id = x or term_id = x? For example, I want to return all Single (type_id = 1) and Basic (level_id = 1) membership plans. I'm trying to avoid additional SQL queries, as the data is already stored in an array, it's just not easy for me to lookup the data I want.

I'm also trying to avoid a ton of foreach loops. For example, I recently tried the following which sort of works... but what if I have more types than I do levels. There has to be a better way, right?

<?php
$available_types = array();
$available_levels = array();
foreach ($membership_plans as $plan) {
    $available_levels[$plan->level_id] = $plan->level_name;
    $available_types[$plan->type_id] = $plan->type_name;
}
$available_types = array_unique($available_types);// Unique Types
$available_levels = array_unique($available_levels);// Unique Levels
foreach ($available_levels as $level_id => $level_name) {// foreach level
    foreach ($available_types as $type_id => $type_name) {// list each type with level
        echo $level_name.' - '.$type_name;
        // find plans tht match type and level
        foreach ($plans as $plan) {
            // More code goes here, but it didn't work out
        }
    }
}
?>

I have a membership plan array that looks like the following:

Array

    [0] => stdClass Object
        (
            [id] => 1
            [type_id] => 1

Answer 1

You probably want to use array_filter

array_filter(
  $arr, 
  function($v) {
    return (
      $v->type_id == 'x' 
      && ($v->level_id == 'x' || $v->term_id == 'x')
    )
  }
 )

if the x needs to be variable you have the use function($v) use ($var) { And maybe its better to check if the type_id exists.
