PHP多行正则表达式

Question

大家好，我正在尝试为PHP创建一个正则表达式，以使我能够获取报价和作者。如果一切都是一行，那么我就使它工作了，但是将其放到多行中的那一刻，它就停止了工作。我究竟做错了什么？

(\[quote\])(.*)(\|)(.*)(\[\/quote\])

[quote]造船厂的沉默，街道上的沉默，哈根波特的船闸和码头将在您睡觉时抢劫您。|流行的儿童韵律

[quote]让您沉睡。|流行的儿童韵[/ quote]

Answer 1

使用s修饰符（如果在正则表达式分隔符之后附加）。另外，.*通过添加一个使您的非贪婪?：

preg_match_all("~\[quote\](.*?)\|(.*?)\[/quote\]~s", $s, $results,  PREG_SET_ORDER);

输出在$results：

[
    [
        "[quote]Silence in the boatyard, Silence in the street, The Locks and Quays of Haganport Will rob you while you sleep.|-popular children's rhyme[/quote]",
        "Silence in the boatyard, Silence in the street, The Locks and Quays of Haganport Will rob you while you sleep.",
        "-popular children's rhyme"
    ], [
        "[quote]Silence you sleep.|-popular children's rhyme[/quote]",
        "Silence you sleep.",
        "-popular children's rhyme"
    ]
]
