Mongodb \ BSON \ Regex Php:执行类似匹配 [英] Mongodb\BSON\Regex Php: Perform Like Match

问题描述

我看到了以下链接:

https://docs.mongodb.com/php-library/current/tutorial/crud/#regular-expressions https://docs.mongodb.com /manual/reference/operator/query/regex/#perform-a-like-match

在mongo终端正则表达式"/giov/i"上找到:

On mongo terminal regex "/giov/i" Found:

• Mariogiovanni
• 乔瓦尼

在

$cursor = $collection->find([
    'description' => new MongoDB\BSON\Regex(' /giov/', 'i'),

]);

什么也没有回来.为什么?我尝试在该社区找到一些解决方案，但是什么也没有

nothing coming back. Why? I try some solution find on this community but nothing

推荐答案

删除正则表达式定界符，因为它们未在MongoDB\BSON\Regex中使用:

Remove the regex delimiters since they are not used in MongoDB\BSON\Regex:

$cursor = $collection->find([
    'description' => new MongoDB\BSON\Regex('giov', 'i'),

]);

如果您遵循第一个参考，答案是非常明显的链接:

以下示例列出了zips集合中的文档，其中城市名称以"garden"开头，而州为德克萨斯州.

The following example lists documents in the zips collection where the city name starts with "garden" and the state is Texas:

<?php

$collection = (new MongoDB\Client)->test->zips;

$cursor = $collection->find([
    'city' => new MongoDB\BSON\Regex('^garden', 'i'),
    'state' => 'TX',
]);

foreach ($cursor as $document) {
   printf("%s: %s, %s\n", $document['_id'], $document['city'], $document['state']);
}
