PHP 使用 preg_match 進行多維數組搜索

Question

我的目標是使用 Preg Match 在多維數組中搜索（只是我的 SQL 中的 LIKE 運算符搜索），我嘗試了所有可能的方法，我知道但對我沒有任何效果。 我當前的搜索代碼效果很好，但只有完全匹配，我想只從數組中搜索標題和類別，以便它與短語%Action%匹配並提取可能的值或數組

這是我的 PHP 代碼

function searchMultiDimensionalArray($array, $key, $value) {
    $results = array();
    if (is_array($array)) {
        if (isset($array[$key]) && $array[$key] == $value)
            $results[] = $array;
        foreach ($array as $subarray)
            $results = array_merge($results, searchMultiDimensionalArray($subarray, $key, $value));
        }
    return $results;
 }

這是演示數組數組

調用 function

//Find title with extact match
$finder_title = searchMultiDimensionalArray($array_data, 'title', 'Road Fury');
//Find category which isn't working
$find_cat = searchMultiDimensionalArray($array_data, 'category', 'Action');

Answer 1

您好，使用函數式編程方法查看此解決方案：

<?php

function searchMultiDimensionalArray($array, $key, $value) {

    if(!is_array($array)) {
        return preg_match("/$value/i", $array);
    }

    return array_filter($array, function($item) use ($key, $value){
       return  (isset($item[$key]) && !is_array($item[$key]) && preg_match("/$value/i", $item[$key])) 
       || searchMultiDimensionalArray($item, $key, $value);
    });
}
