Question

我有两个URL数组：ArrayA和ArrayB。我需要知道ArrayB的哪些URL（可能有多次出现相同的URL）与ArrayA的哪些URL（此处的URL是唯一的）相匹配。

我将通过foreach循环遍历ArrayB并尝试匹配网址。

ArrayA包含以下网址：

clients / {client_id} / projects / {project_id}
clients / {client_id}
活动/ {activity_id}
活动/ {activity_id} /编辑

ArrayB包含以下网址：

clients / 123 / projects / 23
clients / 5 / projects / 12
clients / 1
clients / 52
活动/ 52
活动/ 35
活动/ 52 /编辑
活动/ 35 / edit

我想将ArrayB中的每个URL匹配到ArrayA中的正确URL，并在找到匹配项后立即对其执行操作（因此无需保存任何内容）。 ArrayB中的一条路由始终仅与ArrayA中的一条路由匹配（因此n：1关系）。

$arrayA = getPossibleRoutes();
$arrayB = getActivatedRoutes();

// YOUR CODE

我希望创建一个foreach循环（最有可能嵌套的一个循环），该循环遍历ArrayA或ArrayB并在找到匹配项后立即执行操作。

Answer 1

尝试：

foreach($arrayA as $item){
        $patterns[$item] = preg_replace(['/(\{\w*\})/','/\//'],['\d+','\/'],$item);
}

foreach ($arrayB as $arr) {
        foreach($patterns as $route => $pattern){
                if (preg_match('/^'.$pattern.'$/', $arr))
                {
                        //the matched route is $route
                }
        }
}

Answer 2

您可以执行以下操作：

<?php
    $arrayA = [
    "clients/{client_id}",
    "activities/{activity_id}",
    "activities/{activity_id}/edit",
    "test/{test}/test",
    "random/random/{random_id}",
    "clients/{client_id}/projects/{project_id}",
    "unmatched/path",
];

$arrayB = [
    "clients/123/projects/23",
    "clients/5/projects/12",
    "clients/1",
    "clients/52",
    "activities/52",
    "random/random/1",
    "activities/35",
    "activities/52/edit",
    "test/1/test",  
    "activities/35/edit",
    "not_found_url/35"
];

foreach($arrayA as $arr) {
    $key = substr_count($arr, '/');
    $getFirstWord = explode("/",$arr);
    $sortedA[$getFirstWord[0]][$key] = $arr;

}

foreach($arrayB as $arr) {
    $getFirstWord = explode("/",$arr);
    if(array_key_exists($getFirstWord[0],$sortedA)) {
        $urls[$arr] = $sortedA[$getFirstWord[0]][substr_count($arr, '/')];
    }
}


foreach($urls as $key => $url)
  print_r($key." => ".$url."<br>");

?>

输出将是：

clients/123/projects/23 => clients/{client_id}/projects/{project_id}
clients/5/projects/12 => clients/{client_id}/projects/{project_id}
clients/1 => clients/{client_id}
clients/52 => clients/{client_id}
activities/52 => activities/{activity_id}
random/random/1 => random/random/{random_id}
activities/35 => activities/{activity_id}
activities/52/edit => activities/{activity_id}/edit
test/1/test => test/{test}/test
activities/35/edit => activities/{activity_id}/edit

编辑：此代码现在应该是动态的，对于任意数量的url /路径。它还支持未找到的URL和/或路径。编辑2：优化

将各种带有ID的网址与带有占位符的网址进行匹配
