PHP怎么实现正则匹配所有括号中的内容
PHP实现正则匹配所有括号中的内容的方法:首先创建一个PHP文件;然后输入PHP正则匹配代码,如:“preg_match_all($strPattern, $strSubject, $arrMatches);”;最后运行该文件即可。
PHP怎么实现正则匹配所有括号中的内容?
正则表达式:(?<=【)[^】]+
注:以匹配中文括号中内容为例,如果匹配非中文括号,则需要在括号前增加转义符
PHP实现示例:
<?php $strSubject = "abc【111】abc【222】abc【333】abc"; $strPattern = "/(?<=【)[^】]+/"; $arrMatches = []; preg_match_all($strPattern, $strSubject, $arrMatches); var_dump($arrMatches);
执行结果:
~ » php mytest/test_preg.php iwaimai@bogon array(1) { [0]=> array(3) { [0]=> string(3) "111" [1]=> string(3) "222" [2]=> string(3) "333" } }
解析:
1、(?<=【)
第一个表达式是一个『非获取匹配』,即匹配括号,但并不获取括号;
2、[^】]+
第二个表达式中[]匹配单个字符,^】代表除了】的字符,+是限定符代表匹配前面子表达式一次或多次,即匹配除了】的连续多个字符;
组合起来即实现了预期效果~
