preg_match()函数用于执行一个正则表达式匹配,检查模式是否在指定的字符串中出现。 $pattern = '/foo/'; $text = 'bar foo baz'; if (preg_match($pattern, $text)) { // 匹配成功的处理 } 使用匹配结果 preg_match()函数能够将匹配的结果保存在一个数组中,这允许你做进一步的处理或检查。 $pattern =...

The pcre2_match() options that are supported for JIT matching are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. The PCRE2_ANCHORED option is not supported at match time. If the PCRE2_NO_JIT op...
MATCH_LIMIT_DEPTH can otherwise be set to some different numeric # value (or even the same numeric value as MATCH_LIMIT, though no longer # defined in terms of the latter). # AC_ARG_WITH(match-limit-depth, AS_HELP_STRING([--with-match-limit-depth=N], [default limit on ...
PCRE2 provides some protection against this: see the pcre2_set_match_limit() function in the pcre2api page. There is a similar function called pcre2_set_depth_limit() that can be used to restrict the amount of memory that is used....

16. 17. 在上面的代码中,我们定义了一个正则表达式模式"a.*d",表示匹配以字母a开始,以字母d结束的字符串。然后,我们定义了一个待匹配的字符串"abcd"。接着,我们利用pcre2_match()函数进行正则表达式匹配,并将结果保存在result变量中。最后,我们根据匹配结果输出不同的提示信息。
