php - 如何使用 RegEx 排除 [ ] 中的符号

Question

我正在使用 PHP preg_match_all，这是我目前所能得到的......

[A-Za-z+\W]+\s[\d]

唯一的问题是我需要\W 不是 "。

所以我试过:

[A-Za-z+[^\dA-Za-z"]\s?]+\s[\d]


[A-Za-z+]\s?+[^A-Za-z\d"]?\s[\d]

除其他外，它只是失败了，我真的不明白为什么。

编辑:

这是完整的正则表达式；

([A-Z][a-z]+\s){1,5}\s?[^a-zA-Z\d\s:,.\'\"]\s?
[A-Za-z+\W]+\s[\d]{1,2}\s[A-Z][a-z]+\s[\d]{4}

我把它分成两行，第二行以我发布的内容开头。

试图匹配的模式:

    India – Adulterated Tea Powder Seized 18 April 2011
    India – Importer of Haldiram’s Petha Sweet Cubes Issuing Voluntary Recall 26 April 2011
    India – Undeclared Gluten Found in Sweets by Canadian Authorities 27 April 2011
    India – Adulteration Found in Edible Oils 28 April 2011
    India – Viral Disease Affects Chili Crop in Goa 28 April 2011
NOT ---->   Chili – India: Goa”. 8 April 2011
    Ivory Coast – Potential Cocoa Quality Decline despite Sufficient Surplus 11 April 2011
    Japan – Sanuki Kanzume Co. and Failure to Comply with FDA Standards 27 April 2011
    Madagascar – Toxic Sardines 14 April 2011
    Madagascar – Update: Toxic Sardines 26 April 2011

Answer 1

您显示的模式匹配所有字母和非单词字符。唯一不包含在模式中的是数字，您也不想匹配双引号。

[^\d\"_]+\s\d

编辑:

我可能是错的，但从示例输入来看，您似乎只是在尝试匹配所有没有双引号的行。如果是这样的话，这样的事情就容易多了，我什至将日期与字符串的其余部分分开进行了分组。如果您不需要对 sting/date 进行分组，则只需删除所有括号。

<?php
error_reporting(E_ALL);
$str = "    India - Adulterated Tea Powder Seized 18 April 2011
    India - Importer of Haldiram’s Petha Sweet Cubes Issuing Voluntary Recall 26 April 2011
    India - Undeclared Gluten Found in Sweets by Canadian Authorities 27 April 2011
    India - Adulteration Found in Edible Oils 28 April 2011
    India - Viral Disease Affects Chili Crop in Goa 28 April 2011
    Chili - India: Goa\". 8 April 2011
    Ivory Coast - Potential Cocoa Quality Decline despite Sufficient Surplus 11 April 2011
    Japan - Sanuki Kanzume Co. and Failure to Comply with FDA Standards 27 April 2011

preg_match_all("/^([^\"]+?)(\d?\d\s[a-z]+\s\d{4})$/im", $str, $m);
echo '<pre>'.print_r($m, true).'</pre>';
?>
