Question

我正在寻找php中的正则表达式，而没有达到我的目标... 这是我的字符串：

$params =  [
        AdsInsightsFields::IMPRESSIONS,
        AdsInsightsFields::INLINE_LINK_CLICKS,
        AdsInsightsFields::SPEND,
        AdsInsightsFields::CLICKS,
        AdsInsightsFields::IMPRESSIONS,
        AdsInsightsFields::REACH,
        AdsInsightsFields::GENDER_TARGETING
    ];

    $cursor = $this->Entity->getInsights($params, ['end_time' => (new \DateTime('now'))->getTimestamp()]);

我想用引号将带有换行符的句段检索，而不用引号将不带换行符的段检索出来。

这是我当前的REGEX：

$string = 'xxxxxxxxxxxx "segment

to

recovered with line breaks" xxxxx "other segment without line break" xxxx';

你能把我带走吗？

使用积极的前瞻匹配换行符：

$string = 'xxxxxxxxxxxx "segment

to

recovered with line breaks" xxxxx "other segment without line break" xxxx';

preg_match_all('/"(?=[^"]*\R)[^"]*"/', $string, $match);
print_r($match);

(?=[^"]*\R)部分确保比赛中有换行符。

输出：

Array
(
    [0] => Array
        (
            [0] => "segment

to

recovered with line breaks"
        )

)
